Interrupting capacity is the headline here: 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 9 kA at 690 V. A mechanical trip indicator gives a visible flag when the breaker has opened on fault, so a tech walking the line can spot a tripped unit without opening the door. The 110 mm depth means it clears typical gland plates and rear-mounted bus bars without interference. Power loss is rated at 66 W maximum — relevant for thermal calculations inside a sealed enclosure; you'll want to account for that heat load if the panel is NEMA 12 or 4X with limited convection. The 70 °C operating ceiling matches the continuous-current derating table (flat 400 A all the way up), so no need to upsize for a hot electrical room.","metaTitle":"Siemens 3VA2440-7HL32-0CH0 SENTRON MCCB, 400 A, 600–4800 A","metaDescription":"Siemens SENTRON 3VA2440-7HL32-0CH0 molded case circuit breaker, 3-pole, 400 A continuous, interrupting up to 330 kA at 240 V.
