Description
The ABB OT63F3 Switch-Disconnector (1SCA105332R1001) is a three-pole, non-fusible disconnect switch designed for industrial power distribution, motor control, and electrical isolation applications. Rated at 60 A under UL/CSA standards and supporting operating voltages up to 600 V AC under these standards, it provides reliable manual switching for electrical circuits and three-phase motor applications.
Part of ABB’s OT Series, the OT63F3 features a front-operated design with base mounting and DIN-rail mounting compatibility. Its protected clamp terminals help reduce the risk of accidental contact with live electrical connections. The switch supports incoming power connections from either the top or bottom, providing installation flexibility for industrial control panels and electrical distribution assemblies.
The OT63F3 is supplied without an operating handle or shaft, allowing compatible accessories to be selected separately for the intended installation. Its IP20 front protection rating and compact construction make it suitable for integration into compatible industrial electrical enclosures.
