The
Terasaki TemPower2 AR325H 3-Pole Air Circuit Breaker is engineered for high-current, high-fault electrical networks where safety and continuity are paramount. Rated at
2500A with an adjustable current setting range of
1000A to 2500A, this ACB is ideal for
main incomers, transformer feeders, and generator protection in large-scale installations.
Featuring an extra-high AC breaking capacity of 100kA at 440VAC, the AR325H ensures rapid fault interruption and protection of downstream equipment. The advanced LSIG electronic protection unit provides comprehensive protection against overload, short-time, instantaneous, and ground faults.
Designed with a fixed mounting type and built in accordance with IEC 60947-2, the Terasaki AR325H offers Ics = 100% of Icu and Icw = 100% of Icu, ensuring full selectivity and short-time withstand capability. With built-in trip memory and Terasaki’s proven engineering quality, this breaker is a trusted solution for mission-critical power systems.
