Description
The ABB OT60G3-3BS Switch-Disconnector (1SCA162540R1001) is a three-pole switch-disconnector designed for industrial power distribution, motor control, and electrical isolation applications. With a 60 A UL/CSA ampere rating and a maximum operating voltage of 600 V AC under UL/CSA specifications, it provides reliable manual switching for three-phase electrical systems and supports motor applications up to 50 hp at 600 V AC.
Part of ABB’s OT Plus series, the OT60G3-3BS features a compact, modular design with base mounting and DIN-rail mounting compatibility. It includes built-in screw terminals and a direct-mounted black knob handle that can be padlocked. The switch is also suitable for panels with a 45 mm DIN cut-out, offering flexibility for industrial control panel installations.
The switch features IP20 front protection to help reduce the risk of accidental contact with live terminal connections. An optional operating shaft and external handle can be installed for external switching, making the OT60G3-3BS suitable for a range of electrical enclosure configurations.
