Its adjustable thermal-magnetic trip unit covers 189 A to 945 A, so it's sized for motor or feeder protection where the load current lands well below the breaker's frame rating. This MCCB is designed for starter protection (per), meaning it's built to handle motor inrush and coordinate with a contactor and overload relay in a typical motor branch circuit. The interrupting ratings are substantial: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V — so it can sit upstream of a high-fault panel without cascading failure. ## Physical fit and auxiliary configuration The 3VA2163-7MS32-0HL0 measures 105 mm wide, 181 mm tall, and 86 mm deep (4.13 × 7.13 × 3.39 inches). A shunt trip release (STL) is also installed.","metaTitle":"Siemens SENTRON 3VA2163-7MS32-0HL0 MCCB, 63 A, 189-945 A tri","metaDescription":"Siemens SENTRON 3VA2163-7MS32-0HL0 molded case circuit breaker, 3-pole, 63 A continuous, adjustable trip 189-945 A, 330 kA at 240 V.
