OT45E3

The OT45E3 is an ABB OT non-fusible disconnect switch rated for 60A at 600V with 3 poles, designed to isolate motors and other equipment from the power supply for maintenance and safety. It is a switch-only device that opens and closes the circuit but does not provide overcurrent protection, so it is applied together with a fuse or breaker upstream. The OT45E3 carries a UL general purpose rating of 60 amps and an IEC AC-21 rating of 63 amps, so it suits both North American and international applications. The OT45E3 is listed to UL 508 and IEC standards, and its three poles disconnect all three supply lines together, which helps ensure complete isolation of three-phase circuits in 600 volt systems. It mounts on a base or DIN rail, so it fits a wide range of enclosures and control panels. The handle and shaft are sold separately, so you choose the operating handle to suit the installation, such as an ABB selector handle for door-mounted or panel-mounted use. Connections use screw terminals that accept copper conductors only. At about 0.6 pounds, the switch is compact and easy to mount in a crowded panel. Because ABB builds the OT line in several ratings, pole counts, and mounting styles, it is worth confirming the part number, rating, and accessories against your equipment before ordering. This makes the OT45E3 a practical choice for panel builders, electricians, and maintenance teams who need a compact, dependable disconnect for a motor circuit or machine.
