The APS iMCB™ (Smart Metering Circuit Breaker) is an advanced digital protection and monitoring device designed for modern electrical systems requiring high safety, intelligent supervision, and real-time energy management. Unlike traditional miniature circuit breakers, the iMCB integrates protection, metering, monitoring, automation, communication, and remote control into a single compact DIN-rail module.
Built on the MTS3 Smart Electric Safety Supervision and Power Management platform, the iMCB provides comprehensive electrical protection—including overload, short circuit, over/under-voltage, arcing, phase loss, unbalance, and high-temperature alarms. With built-in metering and communication capabilities, it offers full visibility of voltage, current, power, temperature, and energy (kWh) across main and branch circuits.
The iMCB is ideal for industrial, commercial, and infrastructure applications where safety, energy transparency, and predictive maintenance are essential.
What is an iMCB?
An iMCB (Intelligent Miniature Circuit Breaker) is a smart protection device that combines:
Circuit protection
Energy metering
Real-time monitoring
Fault detection & alarms
IoT communication
Remote control
Automation / timer functions
Event logging
It uses microcontroller-based electronic protection in combination with thermal–magnetic tripping. The iMCB is modular, DIN-rail mountable, and expandable with other MTS3 modules.
Core capabilities of the iMCB include:
Overload + short-circuit protection
Adjustable maximum current & power limits
High-temperature protection
Over/under-voltage detection
Arcing fault protection
Real-time metering of voltage, current, power, and kWh
Remote ON/OFF switching using APP or software
Integration via Wi-Fi, LAN, RS485, GSM/GPRS, NB-IoT, Zigbee, LoRa (through communication module)
The iMCB functions as both a protection device and a smart monitoring unit, enabling predictive maintenance and energy efficiency improvements.
