The interrupting capacity is 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V — meaning it can safely clear a fault up to those levels depending on the system voltage. A 5 kA short-time rating (limited to 1 s) supports selective coordination downstream. Dimensions are 110 mm deep, 138 mm wide, 248 mm tall — a standard 3-pole MCCB footprint for a 400 A frame.","metaTitle":"Siemens 3VA2440-5HL32-0AF0 SENTRON MCCB, 400 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA2440-5HL32-0AF0 molded case circuit breaker, 400 A, 3-pole, 187 kA at 240 V.
