  • Product description

    LOTO Knife Switch Lockout Device | For handles up to 130 mm | Ø15.2 mm | Reinforced PA Nylon | Red

    A LOTO safety lockout device designed to mechanically lock out knife switch operating handles and protect against accidental or unauthorized switching during electrical equipment maintenance, repair, or inspection work. The device is manufactured from reinforced technical PA nylon using single-piece injection molding, offering high impact and bending resistance. Suitable for knife switch handles with a length under 130 mm and a diameter of 15.2 mm. Operating temperature range from −20 °C to +120 °C.

    Main Idea

    This is a specialized LOTO device for locking out a knife switch handle. Once placed over the handle, it physically restricts the ability to operate the switch, and securing it with a safety padlock helps ensure that the switch cannot be toggled until the responsible worker removes the lockout.

    Material
    Reinforced PA nylon
    Handle Length
    Less than 130 mm
    Handle Diameter
    Ø15.2 mm
    Temperature
    −20...+120 °C

    Operating Principle

    The lockout device is placed over the knife switch operating handle to physically restrict its movement. The design covers the handle operation area, creating a mechanical barrier against switch toggling.

    Once the lockout device is in place, it is secured with a LOTO safety padlock. Until the padlock is removed, the lockout device cannot be removed normally, leaving the switch handle protected against unauthorized operation.

    What are the benefits of this knife switch lockout device?

    It allows knife switches to be integrated into the LOTO safety procedure and creates a clear mechanical lockout right at the switch operating handle. This is especially relevant during equipment maintenance when the switch must remain in a set safe position.

    Reinforced PA Nylon Construction

    • Made of technical plastic – reinforced PA nylon.
    • Single-piece injection molded construction.
    • Drop and mechanical impact resistant.
    • Bending resistant.
    • Bright red color helps easily identify the safety lockout device.
    • Suitable for use from −20 °C to +120 °C.

    Knife Switch Handle Lockout

    The device is designed for knife switch handles with a length under 130 mm and a handle diameter of 15.2 mm. Before selecting the lockout device, it is mandatory to verify the actual dimensions of the specific switch handle and ensure the lockout structure can be properly fitted.
