Description

The HMC390 is a 3-pole, 100A MCB with a C-type tripping curve and a 15kA breaking capacity, designed for high-current three-phase sub-main protection in commercial and industrial distribution. The C-type characteristic provides greater tolerance for inrush currents from motors, transformers, and electronic equipment.
At 100A per pole and 4.5 DIN rail modules, the HMC390 is suitable for protecting feeders to downstream three-phase distribution boards or large three-phase loads in commercial premises. Flexible conductors up to 50mm² and rigid conductors up to 70mm² can be connected.
IP20 rated, RoHS compliant, and operational from -25°C to +70°C, the HMC390 is compatible with the full range of HMB/HMC auxiliary accessories including auxiliary contacts, shunt trips, and padlockable locking kits.
