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 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.
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.
