The
Terasaki TemPower2 AR332H 3-Pole Air Circuit Breaker is engineered for high-fault, high-current electrical networks where operational safety and system continuity are essential. With a
3200A frame size and an adjustable current setting range of
1280A to 3200A, this ACB is ideal for
main incomers, generator protection, transformer feeders, and heavy industrial panels.
Featuring an extra high AC breaking capacity of 100kA at 440VAC, the AR332H ensures rapid fault clearance even under extreme short-circuit conditions. Its LSIG electronic protection unit provides comprehensive protection against overloads, short-time faults, instantaneous faults, and ground faults.
Designed with a fixed mounting type and manufactured in accordance with IEC 60947-2, the Terasaki AR332H delivers Ics = 100% of Icu and Icw = 100% of Icu, ensuring superior selectivity and short-time withstand capability. Built-in trip memory and Terasaki’s proven engineering make this ACB a dependable choice for mission-critical power systems.
