The Terasaki TemPower2 AR316H Digital Air Circuit Breaker is engineered for high-fault, mission-critical electrical networks requiring precise protection and full neutral isolation. Featuring a 4-pole design and fixed mounting type, this ACB is ideal for main incomers, generators, and transformer protection in industrial and large commercial facilities.
Rated at a 1600A frame size with an adjustable current setting range of 640A to 1600A, the AR316H provides flexibility for a wide range of system requirements. Its extra high AC breaking capacity of 100kA at 440VAC ensures exceptional fault-clearing performance, even in severe short-circuit conditions.
The integrated digital LSIG protection unit delivers accurate, stable, and selective protection against overloads, short-time faults, instantaneous faults, and earth faults. Fully compliant with IEC 60947-2, the Terasaki TemPower2 AR316H offers Ics = 100% of Icu and Icw = 100% of Icu, ensuring maximum system reliability and continuity of service.
