The
Terasaki TemPower2 Digital AR316H 4-Pole Air Circuit Breaker combines advanced digital protection with robust mechanical construction for high-current industrial and commercial installations. Designed with a
fixed mounting type, this ACB delivers precise overload, short-circuit, instantaneous, and earth fault protection via its
digital LSIG system.
Rated at 1000A with an adjustable current range of 500A to 1250A, and an extra high AC breaking capacity of 100kA, the AR316H ensures rapid fault clearing, protecting equipment and maintaining continuity of service in high-fault environments.
Compliant with IEC 60947-2, the Terasaki TemPower2 Digital ACB offers Ics = 100% of Icu and Icw = 100% of Icu, providing full short-time withstand capability and maximum selectivity. The built-in trip memory and digital interface simplify monitoring, diagnostics, and maintenance. Ideal for main incomers, generators, transformers, and critical distribution boards.
