Siemens SENTRON 3VA1010-2ED36-0HA0 — 100 A MCCB with Shunt Trip
The Siemens SENTRON 3VA1010-2ED36-0HA0 is a 3-pole molded case circuit breaker (MCCB) designed for line protection in distribution panels. It carries a continuous current rating of 100 A at 40 °C, with minimal thermal derating up to 70 °C (91 A at 70 °C). The TM210 thermal-magnetic overcurrent release provides fixed thermal and magnetic trip settings for standard feeder and branch-circuit protection. Breaking capacity varies by system voltage: 52.5 kA at 240 V AC, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V. This covers most low-voltage industrial distribution scenarios up to 690 V, though the 7.5 kA limit at higher voltages means it is not suited for high-fault-current 690 V applications without upstream current limitation. The auxiliary release is a shunt trip (STL), allowing remote tripping via a control signal — useful for emergency-stop circuits or remote load shedding. Rated insulation voltage is 800 V, and maximum power loss is 25 W. Operating temperature range is -25 °C to +70 °C, with storage from -40 °C to +80 °C.
Mounting and Panel Fit
Dimensions are 130 mm height, 76.2 mm width, and 70 mm depth — a standard 3-pole MCCB footprint for DIN-rail or panel-mount installation. The 76.2 mm width (3 inches) matches the typical 3-pole MCCB slot in Siemens SENTRON distribution boards. Depth of 70 mm leaves clearance for rear-connected busbars or cable lugs.
