The
Terasaki TemPower2 AR316H 3-Pole Air Circuit Breaker is engineered to protect electrical systems exposed to extremely high short-circuit levels. Rated at
1000A frame size with an adjustable current setting range of
500A to 1250A, this ACB is ideal for
main incomers, generators, and transformer feeders in heavy-duty power distribution networks.
Featuring an extra high AC breaking capacity of 100kA at 440VAC, the AR316H provides superior fault-clearing performance, ensuring equipment protection and operational continuity. Its LSIG electronic protection unit offers comprehensive coverage against overload, short-time, instantaneous, and ground faults.
Designed with a fixed mounting type and built to IEC 60947-2 standards, the Terasaki AR316H delivers Ics = 100% of Icu and Icw = 100% of Icu, guaranteeing maximum selectivity and short-time withstand capability. Built-in trip memory and Terasaki’s proven engineering make it a reliable solution for mission-critical power systems.
