1. Overview
The Y952 is a project-configured electrical safety distribution box for construction sites, temporary installations, and other locations that require local circuit protection and traceable electrical events. It can combine protection devices with optional voltage, current, residual-current, temperature, circuit-status, alarm, and event-recording modules.
Local devices perform protection actions. Network services, the management platform, and the mobile app can report status and events, but they do not replace local protection.
Global power notice: Each cabinet is built for a specific project and destination market. Confirm the nominal voltage, frequency, phase and conductor arrangement, earthing system, prospective short-circuit current, upstream protection, and local compliance requirements before ordering or installation. The site supply must match the nameplate and approved documents.
Typical applications include construction power distribution, temporary facilities, high-risk work areas, and sites that require event records and remote notification.
2. Ordering Information
Y952 is the series designation. Circuit count, incoming arrangement, protection devices, monitoring modules, communication, and enclosure construction are project-specific.
Required Order Information
| Item | Required Details |
|---|---|
| Distribution Arrangement | Installation level, incoming method, circuit count, and upstream/downstream coordination |
| Site Supply | Nominal voltage, frequency, phase/conductors, earthing system, prospective short-circuit current, and upstream protection |
| Circuits and Loads | Rated current, load type, starting current, duty, and operating method |
| Protection | Overload, short circuit, residual current, overvoltage, undervoltage, phase loss, overtemperature, or other required functions |
| Monitoring | Voltage, current, residual current, temperature, circuit state, range, accuracy, and sampling interval |
| Actions and Reset | Circuit trip, local indication, notification, manual reset, and recovery rules |
| Events and Network | Required event fields, retention, export, platform access, notification channels, and offline behavior |
| Enclosure and Market | Material, dimensions, mounting, environment, local codes, certification, marking, and labeling |
The order confirmation defines the final scope. Monitoring, communication, alarms, display, and management functions are included only when specified.
| Scope | Description |
|---|---|
| Standard Architecture | Local protection, circuit-state management, abnormal-condition detection, and event recording |
| Optional Functions | Electrical monitoring, alarms, management access, remote notifications, and display components |
| Project Engineering | Protection combination, settings, action logic, reset process, enclosure, and site-specific adaptation |
3. Key Features

- Designed for construction sites and other high-risk temporary power applications
- Project-defined circuit protection and protection coordination
- Optional electrical and circuit-status monitoring
- Separate protection, local indication, remote notification, and reset actions
- Traceable records for faults, protection actions, handling, and recovery
- Optional platform access, mobile notifications, display, and data export
- Project records can include device data, settings, test results, and installation documents
4. Technical Specifications
Series Parameters
| Parameter | Specification |
|---|---|
| Product Type | Electrical safety distribution box |
| Input Supply | Project-specific AC supply; must match the nameplate and order confirmation |
| Frequency | Project-specific 50Hz or 60Hz rating |
| Circuit Count | Project-specific |
| Circuit Rating | Defined by the load list and installed devices |
| Protection Functions | Defined by the risk assessment and installed protection devices |
| Monitoring Functions | Defined by the selected monitoring modules |
| Alarm Methods | Local indication, audible/visual alarm, management notification, or a configured combination |
| Event Records | Fields, time source, retention, query, and export are project-specific |
| Communication | Optional; defined by the site network and management requirements |
| Enclosure | Material, dimensions, ingress protection, mounting, and temperature rating are project-specific |
Required Project Parameters
| Area | Parameters to Define |
|---|---|
| Power | Rated voltage, frequency, phase, conductors, incoming method, and earthing |
| Circuits | Quantity, rated current, load category, and breaker/contactor configuration |
| Protection | Function, setting, action time, breaking capacity, selectivity, and reset method |
| Monitoring | Measured value, range, accuracy, sampling interval, and alarm threshold |
| Events | Trigger, recorded fields, retention, query, export, and recovery state |
| Structure | Enclosure dimensions, material, ingress protection, mounting, and service clearance |
Do not publish fixed protection thresholds, action times, breaking capacity, or monitoring accuracy unless the installed components and test records support those values.
5. Protection, Monitoring, and Events
| Function | Requirement |
|---|---|
| Local Protection | Protection devices and control circuits act locally, independent of cloud availability |
| Monitoring | Monitoring identifies operating conditions and abnormal values; it does not replace a protection device |
| Notification | Local indicators, alarms, platform messages, or mobile notifications report configured events |
| Event Record | Records can include time, circuit, event type, measured value, action, handling status, and recovery |
| Reset and Recovery | The project must define manual or automatic reset conditions and the required safety checks |
Do not restore a tripped circuit remotely until personnel have verified that the fault and associated risk have been cleared.
6. Communication and Operating Boundaries
Network access can provide status viewing, abnormal-event notifications, event synchronization, and management-side traceability. The platform, app, interface, and notification channels depend on the delivered configuration.
When the network is unavailable:
- Local distribution and confirmed protection actions continue without cloud access.
- Remote notifications, management queries, and event uploads may be unavailable.
- Event storage, later upload, and identification of offline events must follow the approved project design.
Management functions support visibility and traceability. Protection settings, action times, breaking capacity, installation safety, and acceptance remain governed by the electrical design, component documents, and test records.
7. Mechanical, Installation, and Testing
- Verify the site supply, load list, earthing, upstream protection, and protection coordination before installation.
- Confirm the enclosure rating, ventilation, temperature, weather exposure, cable entry, and service clearance.
- Install and label power circuits, monitoring wiring, communication wiring, and earthing conductors according to the approved drawings.
- Do not perform live wiring, bypass protection devices, or change protection settings without authorization.
- Qualified personnel must install, set, test, and maintain the cabinet in accordance with local electrical codes.
- Test every configured protection function, local indication, notification, event record, reset method, and circuit state.
- Test insulation, earthing continuity, temperature rise where required, network loss, network recovery, and event synchronization.
Keep the final settings and test results with the project records.
8. Important Notes
- Product Positioning: The Y952 is a local electrical safety product, not merely a cloud-connected monitoring box.
- Protection Is Local: Cloud services and notifications do not replace installed protection devices.
- Monitoring Is Not Protection: Measuring voltage, current, residual current, or temperature does not imply a corresponding trip function.
- Notification Is Not Resolution: An alarm confirms that the system generated a message; personnel must still inspect and resolve the fault.
- Reset Requires Verification: Restore power only after the site procedure confirms that the fault and risk have been cleared.
- Parameters Must Be Defined: Do not claim fixed protection types, settings, action times, or breaking capacity until the delivered components and configuration are confirmed.
- Document Priority: The nameplate, order confirmation, approved drawings, protection-device documents, settings, test records, and destination-market compliance documents govern the delivered unit and installation.
