Breaking capacity is the headline here: 121 kA at 240 VAC, 75.6 kA at 415 VAC, and still 11.9 kA at 690 VAC. That 75.6 kA at 415 V covers most European and Asian industrial networks without needing a current-limiting upstream device. At 690 V the 11.9 kA figure is adequate for many motor-control-center infeeds but should be checked against the transformer's nameplate impedance. The TM240 release means the thermal element is fixed at 80 A (the breaker's frame rating) and the magnetic pickup is adjustable — typical range is 5x to 10x In, though the exact setting depends on the variant. ## Current Derating and Panel Fit The 80 A rating holds from 40 °C through 50 °C ambient — no derating needed in a typical 40 °C switchroom. At 55 °C it drops to 78 A, at 65 °C to 75 A, and at the 70 °C maximum operating ambient it still carries 74 A. That's a shallow derating curve; you can push ambient without losing much headroom. Physical footprint: 76.2 mm wide (3 in), 130 mm tall, 70 mm deep. That's a standard 3-pole MCCB width — drops into a SENTRON panelboard or a DIN-rail mounting plate without surprises.","metaTitle":"Siemens 3VA1180-4EF32-0AA0 SENTRON MCCB, 80A 3-Pole, 121kA a","metaDescription":"Siemens SENTRON 3VA1180-4EF32-0AA0 molded case circuit breaker, 80A, 3-pole, TM240 release.
