We were recently set this challenge by a customer in Abu Dhabi. They are using a number of AB 140M C2E circuit breakers and need a viable way of locking the switch. There's no smooth surface on the breaker to fix a conventional button lockout device.
In the end, we found the answer through Twitter! The manufacturer (Rockwell) guided us a an accessory they make which replaces the existing twist knob with a lockable version. Simple when you know how!
We are pleased to offer this device through our online shop.
is this simply a pop out the old and in with the new knob? Or do you have to take the circuit apart?
