Circuit Breaker Lockout Devices

Circuit breaker lockouts keep breakers in the off position while equipment is serviced. After the breaker is secured in the off position, a padlock is required to ensure the lockout isn't removed by unauthorized personnel. These devices are an integral part of a facility lockout/tagout (LOTO) procedure designed to meet the OSHA standard for the Control of Hazardous Energy (Lockout/Tagout).
