The
Terasaki TemPower2 AR316H 3-Pole Air Circuit Breaker is engineered for electrical installations exposed to extremely high fault levels. Featuring a
rated frame current of 1250A and an adjustable current setting range of
500A to 1250A, this ACB is ideally suited for
main incomers, generators, and transformer feeders in high-capacity power networks.
With an extra high AC breaking capacity of 100kA at 440VAC, the AR316H ensures fast and reliable interruption of severe short-circuit faults, protecting both equipment and personnel. Its LSIG electronic protection unit provides complete protection against overload, short-time, instantaneous, and ground faults.
Designed with a fixed mounting type and manufactured in accordance with IEC 60947-2, the Terasaki AR316H offers Ics = 100% of Icu and Icw = 100% of Icu, ensuring full service continuity and exceptional short-time withstand strength. Built-in trip memory and Terasaki’s proven engineering make this ACB a trusted solution for mission-critical power distribution.
