The Terasaki TemPower2 AR325H Digital Air Circuit Breaker is engineered for high-current, high-fault environments where intelligent protection and system reliability are essential. Featuring a 4-pole design and a rated current of 2500A, this ACB provides complete protection including neutral conductor protection, making it ideal for modern low-voltage power networks.
Equipped with a digital LSIG electronic trip unit, the AR325H delivers precise and configurable protection against overloads, short-time faults, instantaneous faults, and ground faults. Its extra high breaking capacity of 100kA at 440VAC makes it suitable for installations exposed to extreme fault levels.
Designed with a fixed mounting type and compliant with IEC 60947-2, the Terasaki AR325H offers Ics = 100% of Icu and Icw = 100% of Icu, ensuring maximum service continuity and fault-withstand strength. It is widely used in main incomer panels, data centers, utilities, hospitals, and heavy industrial facilities.
