It carries a TM210 thermal-magnetic overcurrent release — the '210' designates a fixed thermal trip at 80 A with a magnetic short-circuit pickup of 10× In, so it handles moderate inrush without nuisance tripping while clearing hard faults fast. Breaking capacity is the headline here: 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. That 75.6 kA at 415 V is the figure most panel builders will size against — it tells you this breaker can interrupt a bolted fault on a 400 V class system without upstream fuses needing to clear first, as long as the available fault current stays under that mark. The 80 A rating holds flat from 40 °C through 50 °C. At 55 °C it derates to 76.8 A, at 60 °C to 75.2 A, at 65 °C to 73.6 A, and at 70 °C to 72 A. Operating ambient range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. ## Auxiliaries and releases The shunt trip lets a remote signal (PLC, E-stop relay, fire alarm) force the breaker open — essential for emergency-off circuits that need to drop the load without an operator at the handle. The HQ aux switches provide position feedback for status monitoring or interlocking. ## Mechanical endurance and footprint Rated for 15,000 mechanical operations — typical for a panel main or feeder breaker that sees a few cycles per day. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth. The 76.2 mm width (3-inch pitch) fits standard Siemens SENTRON mounting bases and busbar systems; the 70 mm depth leaves room for rear-connected busbars in a 200 mm deep enclosure.","metaTitle":"Siemens 3VA1080-4ED36-0KC0 SENTRON MCCB, 80A, 3-Pole, 121kA","metaDescription":"Siemens SENTRON 3VA1080-4ED36-0KC0 molded case circuit breaker, 80A rated continuous current, 3-pole, TM210 release, shunt trip, 121kA at 240V.
