It is designed specifically for line protection — meaning it sits at the feeder or main distribution point, not on a motor or branch circuit. The interrupting capacity is 187 kA at 240 V, stepping down to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V, so the voltage class of your distribution system determines which fault level this breaker can clear. The 3-pole construction covers three-phase systems. ## Physical Fit and Mounting Dimensions are 248 mm height, 138 mm width, 110 mm depth. The 110 mm depth is the front-to-back panel space required, including the handle and terminals. No undervoltage release or ground-fault module is included — those are separate add-ons if your application requires them.","metaTitle":"Siemens 3VA2440-5HL32-0AG0 SENTRON MCCB, 400 A, 3-Pole, 110","metaDescription":"Siemens SENTRON 3VA2440-5HL32-0AG0 molded case circuit breaker, 400 A continuous, 3-pole, line protection.
