The overcurrent release is a TM210 thermal-magnetic type, meaning it combines a thermal bimetal for overload protection and a magnetic coil for short-circuit response, no electronic adjustment needed. Breaking capacity is substantial for its size: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V — figures that cover most low-voltage distribution panels and motor control centers. This breaker does not carry an auxiliary contact, undervoltage release, phase-failure detection, or ground-fault monitoring — it's a bare line-protection device with a shunt trip (STL) as the auxiliary release option. The 3VA1020-4ED36-0HA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep — a compact footprint for a 3-pole MCCB at this breaking capacity.","metaTitle":"Siemens 3VA1020-4ED36-0HA0 SENTRON MCCB, 20 A, 3-Pole, TM210","metaDescription":"Siemens SENTRON 3VA1020-4ED36-0HA0 molded case circuit breaker, 20 A rated continuous current, 3-pole, TM210 release, 121 kA at 240 V.
