The TM240 overcurrent release is a fixed thermal-magnetic type — no interchangeable trip units, so what you see on the nameplate is what you get. The 220 kA breaking capacity at 240 V (154 kA at 415 V, 121 kA at 440 V) puts this squarely in the high-interrupting category for industrial distribution where fault currents are serious. This is typical for machinery safety circuits where a loss of control power should open the main disconnect. The 3VA1163-6EF32-0CA0 measures 76.2 mm wide, 130 mm high, and 70 mm deep — a standard SENTRON 3VA frame size that drops into the same mounting footprint as other 3VA breakers in this current class. Front protection is IP40, meaning tools or fingers won't accidentally contact live parts, but the breaker itself isn't sealed against dust ingress or washdown. It's a panel-interior device, not a standalone enclosure. The storage minimum matters if this sits in an unheated warehouse before installation — the breaker can handle a deep freeze without damage.","metaTitle":"Siemens 3VA1163-6EF32-0CA0 SENTRON MCCB, 63 A, 220 kA at 240","metaDescription":"Siemens SENTRON 3VA1163-6EF32-0CA0 molded case circuit breaker, 63 A rated, 220 kA breaking at 240 V.
