Item description
This listing is for Square D's version of the very popular Siemens breaker lock ECQL1 that I sell 1000's of a year. These work very well to keep a circuit break either locked on of off!!
To be clear these are for SQ D QO breakers only, if your looking for the other ones search for ECQL1 ( you'll find me) they fit most other breakers
The last photo is where you can use a breaker lock to lock off a shorted line, permanently or until you can get it fixed!!
