Siemens 3VA1163-5EF42-0AC0 — 63 A SENTRON MCCB with TM240 Release
The Siemens 3VA1163-5EF42-0AC0 is a 4-pole molded case circuit breaker from the SENTRON series, rated 63 A at 40 °C and carrying a TM240 thermal-magnetic overcurrent release.
The 63 A continuous rating holds from 40 °C through 50 °C without derating; at 55 °C it drops to 62 A, at 65 °C to 60 A, and at 70 °C to 58 A — useful to know if the breaker lives in a hot enclosure or next to other heat sources.
Integration and Auxiliary Switching
The breaker ships with two factory-fitted HQ auxiliary switches, giving you status feedback for PLC inputs or alarm annunciation without adding a separate accessory. Dimensions are 130 mm height, 101.6 mm width, 70 mm depth (–) — standard SENTRON 3VA footprint for 4-pole frames, so it drops into the same panel cutout as other 3VA breakers of this size.
