The Siemens SENTRON 3VA1110-6EF36-0HA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current at 40 °C, with a TM240 thermal-magnetic overcurrent release.
The TM240 release means the thermal element is calibrated for a 100 A frame with a fixed magnetic trip threshold. For a site electrical engineer working selectivity tables, this breaker sits in the SENTRON 3VA family where downstream MCBs (SENTRON 5SL or 5SY series) coordinate cleanly up to the listed interrupting levels. The 15 000 mechanical endurance cycles (latching) are typical for a distribution MCCB — not a switching device, but rated for occasional manual isolation during maintenance.
Panel fit and mounting constraints
At 76.2 mm wide (roughly 3 inches) and 70 mm deep, this breaker fits standard SENTRON 3VA mounting footprints. No auxiliary contacts or shunt trip are integrated, but the design accepts the 3VA9688-0BL30 shunt trip (STL) as a field-addable accessory if remote tripping is needed later.
