Smart switch integrating protection, monitoring and control for LV branch and end circuits
The Massivene Smart Miniature Circuit Breaker is designed for smart LV branch and end circuits. It adds operating monitoring, IoT communications, energy metering and remote open/close control to the conventional miniature circuit breaker’s overload, short-circuit and earth-leakage protection.
The product mounts on a standard DIN rail and collects circuit voltage, current, leakage current, internal temperature, energy use and breaker status in real time. Connected to an upper-layer management system, it provides online sensing, abnormal-condition protection and remote control for LV end circuits.
Supports overload, short-circuit, earth-leakage, overvoltage, undervoltage, overtemperature and load-limit protection. Three-phase models add phase-loss protection and three-phase unbalance alarms.
Collects voltage, current, leakage current, internal temperature, energy use and open/closed status.
Supports remote automatic opening, closing and scheduled open/close control, with breaker status feedback.
Connects to a management platform through the applicable communications interface for device data acquisition, status monitoring and central management.
