At 690 V it still clears 7.5 kA, so it handles mixed-voltage lineups without a separate current-limiting fuse upstream. The only auxiliary is the shunt trip (STL) with two HQ auxiliary switches (3VA9688-0BL30). If your BOM calls for undervoltage or ground-fault, this isn't the variant. ## Thermal derating — the number that matters Above that it starts to taper: 19.2 A at 55 °C, 18.8 A at 60 °C, 18.4 A at 65 °C, and 18 A at 70 °C. If your panel ambient runs at 65 °C, you're losing 8 % of the nominal current — factor that into the load calculation, not the nameplate. Compared to the sibling 3VA1020-3ED36-0AA0 (same frame, same TM210 release), the -0HC0 adds the shunt trip and two HQ auxiliaries from the factory. The -0AA0 ships without them, so if your panel already has external shunt-trip wiring, the -0HC0 saves a field-install kit and one wiring step. The 3VA1020-3ED36-0HC0 measures 76.2 mm wide, 130 mm tall, and 70 mm deep.","metaTitle":"Siemens 3VA1020-3ED36-0HC0 SENTRON MCCB, 20A, 3-Pole, 75.6kA","metaDescription":"Siemens SENTRON 3VA1020-3ED36-0HC0 molded case circuit breaker, 20A rated, 3-pole, 75.6kA at 240V.
