Description

Part of the Sentron 3VA5 line, this 50A motor circuit protector provides dedicated short-circuit defense for motor control applications. It utilizes an adjustable magnetic-only TM120M trip unit to handle high inrush currents without nuisance tripping. Mounting into Siemens P1, P2, and P3 panelboards, this 3-pole unit serves as a reliable replacement for legacy ED63A050 devices. Rated for 65kA at 480VAC, it delivers current-limiting performance and HACR compliance.
