The TM210 thermal-magnetic overcurrent release handles the overload and short-circuit curve; the shunt trip (STL) auxiliary release lets a remote signal or undervoltage condition open the breaker independently of the overcurrent trip mechanism. Breaking capacity is 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. Three-pole construction, 70 mm deep, 76.2 mm wide, 130 mm tall — fits a standard 3-pole MCCB footprint on the DIN rail or panel-mount plate. ## Integration Notes This MCCB mounts in a standard 3-pole molded-case footprint. The 76.2 mm width (3 inches) matches the common SENTRON 3VA panel cutout; the 70 mm depth leaves clearance for rear-mounted busbars or a shunt-trip wiring harness. The shunt trip (STL) release requires a separate control voltage to trip — verify polarity and voltage rating from the Siemens accessory catalog before wiring, as the coil is polarity-sensitive on DC circuits. If you need remote status or GF protection, step up to the 3VA1 or 3VA2 series with the appropriate electronic trip unit and communication module.","metaTitle":"Siemens 3VA1020-3ED36-0KA0 SENTRON MCCB, 20A, 3-Pole, 75.6kA","metaDescription":"Siemens 3VA1020-3ED36-0KA0 SENTRON molded case circuit breaker, 20A rated at 40°C, 3-pole, 75.6kA breaking at 240V, shunt trip release, TM210 thermal-magnetic trip.
