Its interrupting capacity reaches 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V — meaning it can safely clear faults at these levels without cascading upstream, a critical parameter for high-fault-current industrial switchboards and motor control centers. This is the starter protection version, designed for motor branch circuits where the MCCB coordinates with a contactor and overload relay. The ETU310M electronic trip unit provides adjustable thermal-magnetic protection curves suited to motor starting inrush, avoiding nuisance trips while still clearing a locked-rotor fault. A shunt trip (STL) is integrated for remote emergency-off or safety circuit integration. The breaker carries a 20 000-cycle mechanical endurance rating, which for a motor-starting application translates to years of daily operation before maintenance is due. Above that, derating begins: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. For a panel with ambient temperatures above 50 °C — common in enclosed motor control centers or outdoor cabinets in direct sun — the effective continuous current drops by roughly 10% at the top of the range. Size your feeder accordingly. The depth is the key dimension for shallow backpanel enclosures — 86 mm means it fits standard 200 mm deep wall-mount cabinets with room for wiring gutters. Mounting is via the SENTRON 3VA base, which accepts plug-in or fixed connections depending on the accessory kit specified.","metaTitle":"Siemens 3VA2163-7MS32-0JH0 SENTRON MCCB, 63 A, 3-Pole, 330 k","metaDescription":"Siemens SENTRON 3VA2163-7MS32-0JH0 molded case circuit breaker, 63 A rated, 3-pole, 330 kA at 240 V.
