The 20 A continuous rating holds flat through 50 °C; above that it derates to 19.2 A at 55 °C and 18 A at 70 °C — relevant for a sealed enclosure with limited convection. Breaking capacity at 415 V (32 kA) is the figure that governs most European 400 V industrial panels; the 52.5 kA at 240 V covers North American 240 V delta or split-phase services. Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall — a compact 3-pole MCCB footprint that fits standard SENTRON panel-mounting patterns. Mechanical endurance is 15 000 cycles, adequate for a line-protection breaker that sees infrequent operation. ## Auxiliary and Trip Configurations The shunt trip (STL) allows remote tripping via a control voltage; the undervoltage release is not fitted on this order code. No communication function, phase failure detection, or ground fault monitoring is integrated — this is a straightforward thermal-magnetic line-protection breaker with basic remote-trip capability.","metaTitle":"Siemens 3VA1020-2ED32-0HH0 SENTRON MCCB, 20 A, 3-Pole, 52.5","metaDescription":"Siemens 3VA1020-2ED32-0HH0 SENTRON molded case circuit breaker, 20 A rated, 3-pole, 52.5 kA at 240 V.
