Breaking capacity steps down with voltage: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 500/690 V. The overcurrent release is a TM210 thermal-magnetic type — fixed thermal and magnetic settings, no electronic adjustment. The auxiliary release is a shunt trip (STL), so you can remotely trip the breaker via a control signal. Dimensions: 130 mm height, 76.2 mm width (3 in), 70 mm depth (2.76 in). The 3-pole footprint is standard for 20 A MCCBs — verify the busbar spacing and enclosure cutout against your existing layout.","metaTitle":"Siemens 3VA1020-2ED36-0KA0 SENTRON MCCB, 20 A, 3-Pole, 52.5","metaDescription":"Siemens SENTRON 3VA1020-2ED36-0KA0 molded case circuit breaker, 20 A rated, 3-pole, 52.5 kA breaking capacity at 240 V.
