Product Description
The DUUKE Circuit Breaker Lock E21A is a specialized device designed for locking out circuit breakers with handle thickness ≤0.67 inch (17mm) and width ≤1.89 inch (48mm). Constructed from impact-resistant and insulating ABS engineering plastic, it provides a reliable solution for locking air switches, enabling effective energy control and ensuring safety during maintenance, repair, or other work scenarios.
Usage Instructions
- Identify the circuit breaker with handle thickness ≤0.67 inch (17mm) and width ≤1.89 inch (48mm) to be locked out.
- Adjust the bottom baffle according to the stroke of the circuit breaker handle.
- Secure the lockout device onto the circuit breaker handle, then rotate the screw rod clockwise by hand to fix it, ensuring the metal tooth block locks securely.
- Insert a safety padlock or hasp through the 7.5mm lock hole to complete the lockout. For multi-person lockout, use a hasp to allow multiple padlocks.
Product Characteristics
The lockout device is made from ABS engineering plastic, offering excellent impact resistance and insulation, making it suitable for various industrial environments. Its adjustable baffle allows adaptation to different circuit breaker handle strokes, enhancing compatibility. The easy-to-use hand-rotating screw rod and metal tooth block design ensure secure locking. The 7.5mm lock hole is compatible with a wide range of safety padlocks and hasps, facilitating flexible lockout/tagout (LOTO) procedures. It is designed for circuit breakers within the specified handle dimensions, providing broad applicability and reliable performance for circuit breaker lockout needs.
Application Scenarios
