The ETU310M is an electronic trip unit with adjustable overload and short-circuit settings. Minimum trip setting is 750 A, maximum is 6 000 A, giving a wide band for coordinating with downstream feeders or motor starting curves. Front IP40 protection means it is suited for enclosed panel mounting where no water ingress is expected.","metaTitle":"Siemens 3VA2450-0MS32-0AA0 SENTRON MCCB, 500 A, ETU310M","metaDescription":"Siemens 3VA2450-0MS32-0AA0 SENTRON molded case circuit breaker, 500 A continuous, ETU310M trip unit, 440 kA at 415 V.
