Description
The ABB OT25F3 Switch-Disconnector (1SCA104857R1001) is a three-pole, non-fusible disconnect switch designed for industrial power distribution, motor control, and electrical isolation applications. With a 25 A rated operational current under IEC specifications and a 30 A UL/CSA ampere rating, it provides reliable manual switching for electrical circuits in industrial control panels and distribution assemblies.
Featuring a front-operated mechanism, the OT25F3 supports both base mounting and DIN-rail installation. Its protected clamp terminals help reduce the risk of accidental contact with live electrical connections. The compact design measures 68 mm high, 35 mm wide, and 56 mm deep, making it suitable for space-conscious electrical installations.
The OT25F3 supports operational voltages up to 750 V AC under IEC specifications and 600 V AC under UL/CSA specifications. The operating handle and shaft are sold separately, allowing compatible accessories to be selected according to the installation requirements.
