What this MCCB carries and where it fits
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. Its interrupting capacity hits 220 kA at 240 V and 154 kA at 415 V — numbers that tell you it is sized for high-fault panels where upstream transformer or bus capacity demands a breaker that clears fast without cascading. The 800 V rated insulation voltage (Ui) confirms it is built for 400/480 V distribution, not just 240 V residential service.
Thermal-magnetic curve and what it means for coordination
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. The IP40 front protection means it is suited for enclosed panel mounting where the door or cover shields the front face — not for open washdown zones. 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.
