ABB SACET3N225 Three Phase Molded Case Circuit Breaker

ABB SACET3N225 is a three-pole molded-case circuit breaker in ABB's SACE Tmax T3N family, rated for 225 A and designed to protect three-phase distribution circuits from overloads and short circuits with a thermal-magnetic trip unit. It is suitable for AC systems up to 600 V, and its breaking capacity is specified as 25 kA at 480 V and 35 kA at 415 V, enabling protection for typical industrial fault currents while supporting coordination with downstream devices. The device is intended for use as main or feeder protection in switchgear and panelboards in industrial and commercial installations, and it conforms to the T3N frame size within the Tmax family, providing consistent trip characteristics with other Tmax MCCBs. Applications include protection of distribution feeders, motor circuits, and panelboard sections in manufacturing facilities, data centers, and processing plants where three-phase protection is required.
