IoT Smart Metering MCCB

MTM5M

The MTM5M smart MCCB is designed for low-voltage AC power grids (50Hz) with a rated insulation voltage of 1000V, current range of 100A~630A, and working voltage up to 400V. It offers energy distribution, protection against overload, short circuits, overvoltage, undervoltage, phase loss, and indirect contact protection to prevent fire hazards from ground faults caused by insulation damage.
