That kind of short-circuit capacity puts it squarely in high-fault applications like large motor control centers or main feeders in industrial plants. ## Ratings that matter for the panel That's unusual; most breakers start dropping at 50 °C or 55 °C. The minimum interrupting rating is 600 A, and the maximum is 4,800 A, covering the range you'd expect for a 400 A frame. Power loss maxes at 66 W, which matters for enclosure heat load calculations. The auxiliary switch block (2 aux + 1 trip alarm + 1 electrical alarm) is also pre-configured, saving panel wiring time. The line protection design means it's set up for feeder duty, not motor protection — pair it with a separate overload relay for motor circuits.","metaTitle":"Siemens 3VA2440-5HL32-0BL0 SENTRON MCCB, 400 A, 3-Pole","metaDescription":"Siemens 3VA2440-5HL32-0BL0 SENTRON molded case circuit breaker, 400 A continuous at 40-70 °C, 3-pole, 187 kA at 240 V.
