This makes it suited for protecting medium-voltage motor feeders where coordination with downstream contactors and overloads is required. An undervoltage release (24 V DC) is factory-fitted as an accessory, allowing remote tripping on loss of control voltage — common in safety circuits and emergency-stop chains. ## Ratings in Context The adjustable overload range is 200–500 A.","metaTitle":"Siemens 3VA2450-5MN32-0BF0 Circuit Breaker, 500A, 55kA @ 415","metaDescription":"Siemens 3VA2450-5MN32-0BF0 IEC frame 630 MCCB, motor protection ETU350M, 500A In, 55kA Icu @ 415V.
