At 240 V this MCCB interrupts 187 kA — that is a very high rating, typical for a main breaker close to the transformer secondary where available fault current is highest. At 415 V and 440 V it still holds 121 kA, and at 500 V it drops to 75.6 kA. The 5 kA rating limited to 1 second is a short-time withstand for selective coordination — it lets the breaker ride through a downstream fault long enough for the branch breaker to clear. The 3VA2440-5HL32-0KC0 measures 248 mm high by 138 mm wide by 110 mm deep. The 110 mm depth means it projects less than 120 mm from the mounting surface, which keeps the gland plate clearance manageable in a 400 mm deep enclosure. The basic switch core is order code 3VA2440-5HL32-0AA0.","metaTitle":"Siemens 3VA2440-5HL32-0KC0 SENTRON MCCB, 400 A, 3-pole","metaDescription":"Siemens SENTRON 3VA2440-5HL32-0KC0 molded case circuit breaker, 400 A rated, 3-pole, line protection, 187 kA at 240 V.
