ASEC Yellow MCB Lockout Type A

The Asec Yellow MCB Lockout Type A (AS11851) is a highly visible and easy-to-use safety device designed to fit virtually any size of Miniature Circuit Breaker (MCB), regardless of its size or hole position. This lockout device is an essential component of any Lockout Tagout (LOTO) safety procedure, helping to protect personnel from accidental machine startup or hazardous energy release during maintenance and servicing.

To use, simply switch off the circuit breaker, place the lockout device over the toggle, and tighten the internal grub screw to secure it in place. The integrated thumbscrew features a clever hinged design, allowing it to fold down. Once folded, a safety padlock can be fitted through the hasp hole, preventing access to the screw and ensuring the breaker cannot be switched back on until the padlock is safely removed.

With its compact 10mm profile and bright yellow finish, this lockout device is highly visible and helps prevent incorrect or unauthorised use of critical switches.
