Its interrupting capacity hits 121 kA at 240 V AC and still delivers 75.6 kA at 415 V — enough to handle high-fault utility feeds or transformer secondaries without cascading upstream breakers. At 55 °C it drops to 78 A, at 65 °C to 75 A, and at the 70 °C maximum operating temperature it still carries 74 A. That thermal curve means you don't lose headroom in a warm panel unless you're pushing the upper limit of the enclosure's dissipation. ## Interrupting ratings by system voltage At 240 V it clears 121 kA symmetrical; at 415 V it handles 75.6 kA; at 440 V it's rated for 52.5 kA; and at 500 V and 690 V it manages 11.9 kA. The 800 A maximum and 400 A minimum frame ratings bracket the 80 A continuous trip — the frame itself is rated for the full interrupting duty, so you aren't frame-limited at the lower trip setting. Dimensions are 130 mm height, 76.2 mm width (3 inches — standard MCCB pole spacing), and 70 mm depth.","metaTitle":"Siemens 3VA1180-4EF36-0AA0 SENTRON MCCB, 80 A, 3-Pole, TM240","metaDescription":"Siemens SENTRON 3VA1180-4EF36-0AA0 molded case circuit breaker. 80 A continuous, 3-pole, TM240 thermal-magnetic release.
