Description

The HMB190 is a single-pole, 100A MCB with a B-type tripping curve and 15kA breaking capacity at 230V AC, designed for high-current circuit protection in commercial and industrial sub-main distribution. The 100A rating supports large single-phase branch circuits or sub-main feeders in commercial premises.
Like the HMB180, it occupies 1.5 DIN rail modules and accepts flexible conductors up to 50mm² and rigid conductors up to 70mm², with a tightening torque of 3.5–5.0Nm. Auxiliary contact and shunt trip accessories are available for remote monitoring or tripping.
RoHS compliant and IP20 rated, the HMB190 is designed for an extended operating temperature range of -25°C to +70°C, suitable for use in demanding indoor and outdoor distribution board environments.
