These figures define the fault-clearing capability at the respective system voltages — important for selectivity studies and SCCR compliance in a distribution panel. The breaker holds full 80 A rating through 50 °C. Above that, current must be derated: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. The derating curve governs panel fill factor and spacing — a tightly packed enclosure with elevated internal temperature will require a larger frame or forced ventilation. Dimensions are 130 mm height, 76.2 mm width (roughly 3 inches — fits standard 3-pole MCCB footprint), and 70 mm depth. Front protection is IP40. The 3VA frame mounts via screw-clamp to a backplate or DIN rail adapter (not integrated). The undervoltage release coil and auxiliary switch wiring terminate on the front-accessible terminals; verify free-wheel diode polarity on the UVR if driven by a PLC digital output.","metaTitle":"Siemens 3VA1080-4ED36-0BC0 SENTRON MCCB, 80 A, line protecti","metaDescription":"Siemens SENTRON 3VA1080-4ED36-0BC0 molded case circuit breaker, 80 A rated, line protection version with TM210 release.
