Accurate Locking: This button circuit breaker locking device features outwardfacing pins and is designed for elbow hole spacing of 7.5MM or smaller, effectively isolating hazardous energy and preventing unauthorized access—ideal for both single pole and multipole circuit breakers. Impact Resistant: Constructed with a robust nylon body and stainless steel pins, this electrical circuit breaker lock is suitable for heavy industrial use. Its insulating materials provide protection against electric shock during operation. Mini Circuit Breaker Lock: The pin output is widened for enhanced compatibility, with a main body height of 41cm and a pin tip distance of 23cm. The button mechanism allows for quick deployment, and it accommodates safety padlocks with a shackle diameter of 9/in for secure fixation. Insulation Performance: Made from nylon material, both the lock body and button components are wearresistant, offering insulation and temperature resistance to ensure safe usage. Use scenarios: Use this lock on electrical panels during maintenance to prevent energization while servicing single pole or multipole circuit breakers. Securely isolate equipment during changeovers or preventive maintenance in heavy industrial settings, ensuring controlled access. Apply in electrical cabinets in factories or warehouses to comply with lockout practices and prevent accidental energizing during repairs or inspections.
