The 3VA2163-7MN32-0BA0 measures 105 mm wide, 181 mm high, and 86 mm deep — a footprint that fits standard panel layouts for 3-pole MCCBs in the 63 A class. The 86 mm depth is the dimension to check against enclosure depth and busbar clearance when retrofitting into an existing panel.
The ETU350M electronic trip unit provides adjustable protection curves and includes phase failure detection — a feature that catches a lost phase before it damages motor loads. An undervoltage release (UVR) is integrated, allowing remote or safety-circuit tripping when control voltage drops. Maximum power loss is 75 W, which factors into enclosure thermal calculations. Rated insulation voltage is 800 V.
The breaker is rated for continuous current of 63 A at ambient temperatures up to 50 °C without derating. At 55 °C the rating drops to 60.48 A, at 60 °C to 59.22 A, at 65 °C to 57.96 A, and at 70 °C to 56.7 A. Operating temperature range is -25 °C to +70 °C; storage range is -40 °C to +80 °C.
