At 240 V it interrupts 440 kA — that is the headline breaking capacity for this frame — and still delivers 242 kA at 415/440 V, 154 kA at 500 V, and 73.5 kA at 690 V. The 800 A rating holds at ambient temperatures up to 50 °C; above that it derates to 780 A at 55 °C, 761 A at 60 °C, 741 A at 65 °C, and 722 A at 70 °C. The 3VA1580 frame measures 320 mm high, 280 mm wide, and 120 mm deep — a large-frame MCCB sized for main or feeder breaker positions in LV switchboards and distribution panels. ## What the TM240 release means for coordination The TM240 designation indicates a thermal-magnetic trip unit with a continuous current rating of 800 A. The thermal element provides overload protection with an inverse-time characteristic; the magnetic element handles short-circuit protection with an adjustable pickup range up to 8000 A.","metaTitle":"Siemens 3VA1580-7GF42-0AA0 SENTRON MCCB, 800 A, 4-Pole, TM24","metaDescription":"Siemens SENTRON 3VA1580-7GF42-0AA0 molded case circuit breaker, 800 A continuous, 4-pole, TM240 release.
