Continuous rating is fixed at 400 A. The 187 kA at 240 V is the interrupting rating for the highest available fault current; at 690 V it drops to 9 kA, which still covers most 690 V motor circuits. That means it drops the breaker if control voltage is lost — useful for emergency-stop chains or safety circuits where a loss of power must open the main. No ground-fault monitoring or communication module on this order code; those are separate add-on options. Footprint is 138 mm wide by 248 mm tall, with a depth of 110 mm. That's a standard SENTRON 3VA form factor — it fits existing 3VA panel cutouts and bus-bar layouts without re-drilling. The basic switch variant (3VA2440-5HL32-0AA0) is the core breaker; this order code adds the UVR and auxiliary switch pack at the factory.","metaTitle":"Siemens 3VA2440-5HL32-0CH0 SENTRON MCCB, 400A, 3-Pole, 187kA","metaDescription":"Siemens SENTRON 3VA2440-5HL32-0CH0 molded case circuit breaker, 400 A continuous, 3-pole, 187 kA breaking capacity at 240 V.
