Product details

Its interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V — figures that govern selectivity and SCCR coordination in high-fault installations.

Maximum power loss is 96 W — relevant for enclosure thermal calculations when grouping multiple breakers on a DIN-rail or mounting plate.

Physical footprint: 138 mm wide, 248 mm high, 110 mm deep. The 3-pole frame fits standard MCCB mounting cutouts in SENTRON distribution boards and retrofit panels. Verify busbar spacing and lug kit compatibility with the existing assembly before committing the BOM line.
