MD50 Motor Disconnect and Interlocked Receptacle Switches Fusible and Non-Fusible

The MD50 Motor Disconnect Switch merges three key product features to provide safe, quick and reliable mating of mobile and fixed motors to power connections.

Features:

• CSA C22.2 No. 14 Listed “Suitable for Motor Disconnect” switch
• IEC-60309-2 pin and sleeve technology
• Mechanical interlock, integrated in a rugged plastic enclosure, prevents the making or breaking under load of plug-connected equipment. The plug must be inserted before the power can be turned “ON”. The plug cannot be removed until the power is turned “OFF”
• Grounding and conduit hub included

The CSA C22.2 No. 14 certification of the MD50 combined with the IEC 60309 technology and the rugged plastic enclosure provides a set of features for motor disconnecting not available in the existing CSA C22.2 No. 4 Receptacle Switch offering.

Interlocked Receptacle Switches are furnished with a factory-installed three-phase four-wire Appleton Powertite®, Crouse-Hinds Style 2 Arktite® receptacle. The fourth wire is connected to the switch equipment grounding terminal and is not a neutral termination. Interlocking linkage between receptacle and switch mechanism prevents insertion or removal of the plug while the switch is in the “ON” position or insertion of any plug other than specified. Grounding lugs are included.
