strength materials The circuit breaker lockout is made from PA6 nylon and improved strength PA66 nylon, providing insulation, durability, and resistance to deformation. Recommended pairing For effective energy isolation and to prevent accidental operation, use this lockout in conjunction with insulated padlocks and safety devices. Wide compatibility Fits a wide range of singlepole, multipole, and any miniature circuit breakers without modifying the panel or the breaker itself, helping keep maintenance tasks safe for workers. User friendly design Builtin fastening screws allow manual locking without tools. The screw thread diameter is larger than before, making tightening more comfortable and laborsaving. Use scenarios Routine panel maintenance: Install the lockout on a singlepole or multipole breaker and apply a padlock to secure energy isolation during service. Multipole breaker servicing: Lockout multiple poles with a single lockout and padlocks to prevent unintended reenergization. Production and testing environments: Use during installation, commissioning, or troubleshooting to ensure the circuit cannot be operated accidentally, protecting workers.
