Breaking capacity reaches 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. The breaker measures 110 mm deep, 138 mm wide, and 248 mm high — a standard MCCB footprint that fits most 3-pole 400 A panel layouts. The 2 HQ auxiliary switches provide status feedback for PLC or indication circuits without needing a separate accessory block. Maximum power loss of 63.5 W should be factored into enclosure thermal calculations. The line-protection designation means it is optimized for feeder and main-switch duty, not motor or generator protection.","metaTitle":"Siemens 3VA2440-5HL32-0AC0 SENTRON MCCB, 400 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA2440-5HL32-0AC0 molded case circuit breaker, 400 A, 3-pole, breaking capacity 187 kA at 240 V.
