Comprehensive Set The kit includes four circuit breaker lockout devices designed to prevent unauthorized operation of circuit breakers. This fourpack provides a readytouse solution for standard lockout applications, ensuring you can secure multiple circuits as needed. Increased Electrical Safety By locking the breaker box, the devices help secure breakers and reduce the risk of accidental reenergization. This prevents electrical hazards during maintenance or servicing and supports safer, more controlled work environments. Effortless Ease of Use Designed for 120277V singlepole circuits, the lockouts offer simple installation and operation. No additional tools are required to lock or unlock the circuit breaker, enabling quick and straightforward energetic isolation when needed. Resilient Material Made from ABS material for durability, these lockout devices withstand demanding conditions. They operate effectively across a temperature range from 50°C to +177°C, making them suitable for varying environments, including industrial settings.
