Feature
* The lock body is made of impact-resistant, corrosion-resistant reinforced polymer with a wide operating temperature range (-50℃ to +177℃). It is robust, durable, and resistant to deformation, making it suitable for industrial electrical isolation applications.
* The lightweight, integrated design allows easy tool-free installation.
* A serrated tooth engagement design with stainless steel screws and toothed blades securely grips the circuit breaker handle, preventing loosening.
* The fixed protective cover adds a physical barrier to prevent the switch from moving to the “ON” position, helping to prevent electrical accidents.
* The molded case circuit breaker lockout requires no tools for installation. Tighten the stainless steel thumb screw to secure the lockout onto the circuit breaker handle, then snap the protective cover over the screw to lock it in place, preventing loosening and avoiding accidental operation.
