100 A, 4-pole SENTRON MCCB with TM210 release and shunt trip
The Siemens SENTRON 3VA1010-2ED42-0JC0 is a 4-pole molded case circuit breaker rated for 100 A continuous current at up to 50 °C ambient, with a TM210 thermal-magnetic overcurrent release and an integrated shunt trip (STL) for remote tripping. The 52.5 kA interrupting rating at 240 V gives it headroom for high-fault panelboards; at 415 V it still breaks 32 kA, and at 690 V it clears 7.5 kA — useful for mixed-voltage distribution where a single breaker frame covers multiple secondary feeds.
Above that it derates linearly: 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C.
Auxiliary and trip configuration
The shunt trip (STL) allows a remote pushbutton, safety relay, or emergency-stop circuit to open the breaker electrically. The integrated auxiliary trip accessory is order code 3VA9688-0BL32.
The 4-pole width (101.6 mm) is standard for a 100 A frame — verify busbar or lug spacing if replacing an older 3-pole unit.
