Walther's Manual Disconnect Switch combines a horsepower-rated switch in a tough, impervious NEMA 4X enclosure for safe motor load disconnect. Our disconnect switches padlock handles to provide 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 and protects it from any surges or possible electrocution. The device can be connected to metallic conduit without interfering with the ground continuity.
