The TM210 thermal-magnetic release handles the overload and short-circuit protection. A built-in shunt trip (STL) gives you remote trip capability, which matters when you're tying the breaker into an E-stop string or a safety circuit. ## Thermal derating you need to know Above that it starts to step down: 19.2 A at 55 °C, 18.8 A at 60 °C, 18.4 A at 65 °C, and 18 A at 70 °C. ## What fits and what doesn't The 3VA1020-2ED36-0HA0 measures 70 mm deep, 76.2 mm wide, and 130 mm high — a standard SENTRON compact footprint that drops into most DIN-rail or panel-mount MCCB layouts. The shunt trip accessory is order code 3VA9688-0BL30 if you need a spare or a separate part number for the BOM.","metaTitle":"Siemens 3VA1020-2ED36-0HA0 SENTRON MCCB, 20 A, 52.5 kA at 24","metaDescription":"Siemens SENTRON 3VA1020-2ED36-0HA0 3-pole molded case circuit breaker, 20 A rated, 52.5 kA at 240 V interrupting rating.
