It's built as a line-protection device, so the trip curve and release are tuned for feeder and main breaker duty, not motor starting. ## Thermal derating — the real-world current you can actually run At 55 °C it derates to 19.2 A, at 60 °C to 18.8 A, at 65 °C to 18.4 A, and at 70 °C to 18 A. That's a gentle slope — you lose only about 10% at the top of the operating range. The rated insulation voltage is 800 V, and the operating temperature span runs from -25 °C to 70 °C, with storage from -40 °C to 80 °C. It mounts via screw terminals and accepts the usual lug or busbar connections for the line and load sides. The IP40 front face means it's fine behind a closed panel door; no special gasketing needed for dry indoor locations.","metaTitle":"Siemens 3VA1020-3ED36-0DA0 MCCB, 20 A, 75.6 kA at 240 V","metaDescription":"Siemens SENTRON 3VA1020-3ED36-0DA0 molded case circuit breaker, 3-pole, 20 A rated, 75.6 kA interrupting at 240 V.
