Its headline rating is a breaking capacity class M with Icu = 55 kA at 415 V — that means it can safely interrupt a fault current up to 55,000 A at that voltage without welding contacts or rupturing the case, which is the spec that governs selectivity coordination in a distribution panel. The thermal-magnetic trip unit (TM240, ATAM) is set for line protection: overload protection Ir adjustable from 28 A to 40 A, and short-circuit protection Ii fixed at 5 to 10 times In (200–400 A).","metaTitle":"Siemens 3VA1140-5EF32-0AA0-ZD00 Circuit Breaker, 55kA @ 415V","metaDescription":"Siemens 3VA1140-5EF32-0AA0-ZD00 circuit breaker, IEC frame 160, 55kA breaking capacity @ 415V, 40A thermal-magnetic protection.
