That is a shallow derate curve — only 6 A lost over a 30 °C rise — so in a warm enclosure with modest ventilation this breaker still carries near its nameplate current. ## Interrupting Capacity — Voltage-Dependent, Not Flat Breaking capacity drops with voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. The 11.9 kA at 690 V is the floor — still adequate for most 690 V motor branch circuits, but if your available fault current at that voltage exceeds 12 kA, you need a higher-rated frame or a current-limiting upstream device. The 75.6 kA at 240 V is the headline figure; it covers high-capacity 120/240 V services common in North American panels. ## Accessories and Releases — Shunt Trip Fitted No undervoltage release, no ground-fault module, no communication function. The basic switch is order code 3VA11803EF320AA0. ## Environmental Range and Storage Storage range is wider: -40 °C to 80 °C, covering cold warehouses and hot shipping containers. ## Panel Fit — DIN Rail or Direct Mount At 76.2 mm wide (3 in), this 3-pole MCCB occupies a standard three-module width on DIN rail or direct-mount plate. Depth of 70 mm (2.76 in) leaves clearance for rear-connected busbars and wiring gutters. Height of 130 mm (5.12 in) fits standard 200 mm tall enclosure backplates with room for cable entry above and below.","metaTitle":"Siemens 3VA1180-3EF32-0JC0 SENTRON MCCB, 80 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1180-3EF32-0JC0 molded case circuit breaker. 80 A rated at 40 °C, 3-pole, 75.6 kA breaking at 240 V.
