Its interrupting capacity hits 187 kA at 240 V AC, 121 kA at 415/440 V, 75.6 kA at 500 V, and 9 kA at 690 V, giving you selectivity headroom well beyond typical 400 A service entrance or feeder duty. The 400 A rating is thermally stable: the breaker carries 400 A continuously at any ambient from 40 °C up to 70 °C, which is unusual — many MCCBs start derating above 40 °C. That means you can mount it in a crowded, warm panel without losing ampacity. The interrupting ratings span the common industrial voltages: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V. ## Integration — Panel Fit & Wiring Dimensions are 248 mm height, 138 mm width, 110 mm depth — a standard SENTRON 3VA frame size that fits the same mounting footprint as other 3VA2 breakers. The 110 mm depth includes the handle and terminals, so check gland-plate clearance if the panel door is shallow. The auxiliary release is an undervoltage release (UVR) — wired separately from the main power path. It's a shunt-trip style that opens the breaker on loss of control voltage.","metaTitle":"Siemens 3VA2440-5HL32-0BA0 SENTRON MCCB, 400A, 3-Pole, 187kA","metaDescription":"Siemens SENTRON 3VA2440-5HL32-0BA0 molded case circuit breaker, 400 A, 3-pole, 187 kA at 240 V interrupting capacity.
