Re: What is this device on the breaker?
Breaker lockout. Usually when you see one, you will not see a service disconnect at the appliance that it serves. Code usually requires either a service disconnect at or within sight of the appliance , or, a breaker lockout device. It's a safety device to protect service personnel. You should have seen a little hole on the breaker lockout where the service tech could put a small padlock.

Re: What is this device on the breaker?
The use of a lockout at the breaker is okay for basically all appliances except air-conditioning or refrigerating equipment, which requires the disconnect to be within sight from readily accessible from the equipment - within 50 feet straightline sight - nothing is permitted to block the view from the equipment to the disconnect.
