Walther's Manual Disconnect Switch combines a horsepower rated switch in a tough, impervious NEMA 4X enclosure for safe motor load disconnect. The padlock handle provides lockout protection, in the "OFF" position, to comply with OSHA Lockout/Tagout regulations. In addition, the enclosure cover cannot be removed from the body until the switch is turned to the "OFF" position.

The nonmetallic enclosure, while abuse and corrosion resistant, is also non conductive, which enhances the safety of the product. The device can be connected to metallic conduit without interfering with the ground continuity.
