Siemens 3VA2225-5HL32-0AA0 Molded Case Circuit Breaker 3P 250A 55kA

The Siemens 3VA2225-5HL32-0AA0 is a 3-pole molded case circuit breaker from the SENTRON range, providing line protection via an ETU320 trip unit with LI (overload and instantaneous short-circuit) function. Rated at In=250 A with a breaking capacity of 55 kA at 415 V (class M per IEC 60947), it operates on AC systems up to 690 V. Connection is via nut keeper kit on both sides, accepting flat-bar conductors up to 25 x 8 mm.
