The interrupting ratings (187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 500 V) tell you where it can be installed in the fault-current hierarchy; 187 kA is main-breaker territory on a large low-voltage switchboard. Motor protection design means the trip curve is shaped to handle inrush without nuisance trips while still clearing a locked-rotor condition. Phase failure detection is integrated — no need for a separate voltage relay on the motor starter. Dimensions are 110 mm deep × 138 mm wide × 248 mm high. Depth of 110 mm leaves room for rear-connected busbars or cable lugs inside a 400 mm deep enclosure.","metaTitle":"Siemens 3VA2440-5MN32-0JL0 SENTRON MCCB, 400 A, 3-Pole, Moto","metaDescription":"Siemens 3VA2440-5MN32-0JL0 SENTRON molded case circuit breaker, 400 A at 40 °C, 3-pole, motor protection design with phase failure detection and 187 kA interrupting at 240 V.
