Description
The ABB OT30F3 Switch-Disconnector (1SCA105068R1001) is a three-pole, non-fusible disconnect switch designed for industrial power distribution, motor control, and electrical isolation applications. Rated at 30 A under UL/CSA standards and suitable for operating voltages up to 600 V AC, it provides reliable manual switching for electrical circuits and three-phase motor applications.
Part of ABB’s OT Series, the OT30F3 features a front-operated mechanism with base mounting and DIN-rail mounting compatibility. Its front-protected clamp terminals help reduce the risk of accidental contact with live electrical connections. The compact design supports integration into industrial control panels, electrical distribution equipment, and machinery installations.
The switch accommodates incoming power connections from either the top or bottom and features an IP20 front protection rating. It is supplied without an operating handle or shaft, allowing compatible accessories to be selected separately according to the enclosure and installation requirements.
