Abstract

The invention provides a handle device. While ensuring the handle locking function of the padlock, even in the unlocked state without the padlock, a protective measure can be implemented so that the human body or objects can be prevented from accidentally touching the handle. contact and cause the circuit breaker to malfunction. For the handle device used as an external accessory device of the circuit breaker to open and close the circuit breaker, the handle (4) of the rotary handle is arranged on the mounting base plate (3) of the handle, and the handle has a lock corresponding to the padlock. A draw-out lock plate (4a), wherein, except for the draw-out area of ​​the lock plate corresponding to the lock position (ON, OFF) of the handle, a height H ratio to the height of the handle is provided on the above-mentioned mounting base so as to surround the handle. h high guardrail (8) for protection, even in the actual use state of the circuit breaker without a padlock, to be able to prevent the switching of the handle caused by inadvertent contact with objects or human bodies.

Description

technical field [0001] The present invention is aimed at a circuit breaker for wiring, etc., and relates to a handle device of the circuit breaker or an external handle device installed on the main body of the circuit breaker as an external accessory device of the circuit breaker for opening and closing operations . Background technique [0002] The above-mentioned circuit breaker for wiring has a handle for opening and closing the main circuit contacts, and is classified into a rocker type handle (vertical type) and a rotary type handle according to different operation types. In addition, as an external accessory device of a circuit breaker, there is known an external operating handle device for manually opening and closing a circuit breaker arranged in a panel from outside a panel such as a switchboard or a control panel. Figure 5 An example of the prior art is shown (refer to patent document 1). [0003] exist Figure 5 In (a) and (b), 1 is a circuit breaker with a rock...
