Versatile compatibility: The circuit breaker lockout device fits a range of breaker specifications, enabling use with singlepole or multipole breakers to support safe operation across diverse power distribution systems. Clear safety and accessibility: The compact, brightly colored design improves visibility in busy environments, helping prevent accidental reenergization during maintenance. Robust and tamperproof construction: Engineered for durability with a structure that resists tampering and requires significant force to compromise, enhancing safety in demanding settings. performance material construction: The lock body is made from nylon PA, delivering strong impact resistance and temperature tolerance while resisting deformation for reliable longterm use. Integrated hanging feature: Includes a builtin hanging hole to pair easily with safety locks and warning signs, delivering a comprehensive solution for secure isolation and clear hazard communication during maintenance tasks. What you gain: Safe isolation, reduced risk of unauthorized reenergization, and a practical, easytouse lockout solution that stays reliable over time. Size and compatibility notes: Designed to accommodate a variety of circuit breakers, including singlepole and multipole configurations, for flexible applicability. Use scenarios: 1) Routine panel maintenance in facilities with both singlepole and multipole breakers, using one device to secure multiple circuits. 2) Planned facility shutdowns requiring lockout across several circuits, with padlocks and warning signs attached via the hanging hole. 3) Field service or temporary repairs where quick, clear isolation is needed and hazard communication is essential.
