Description
The ABB OT30G3-3BS Switch-Disconnector (1SCA162539R1001) is a three-pole, non-fusible switch-disconnector designed for industrial power distribution, motor control, and electrical isolation applications. With a 30 A UL/CSA ampere rating and a maximum UL/CSA operating voltage of 600 V AC, it provides reliable manual switching for three-phase electrical systems and supports motor applications up to 30 hp at 600 V AC.
Part of ABB’s OT Plus switch-disconnector series, the OT30G3-3BS features a compact 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. An operating shaft can be installed for external operation, making the switch suitable for compatible electrical panels and enclosure applications.
The switch features IP20 front protection and a modular construction for convenient installation in industrial control panels. Its design supports top or bottom incoming power connections, while the padlockable handle helps support safe electrical isolation during maintenance.
