Model CP30-BA Features
What is a Circuit Protector?
- Mainly used to protect low capacity control circuits, heaters, motors, solenoid valves, transformers, electronic circuits, etc., that cannot be protected with MCCB.
- Saves space for various control circuits in equipment and control panels, etc.
Circuit Protector Features

Open/close type small terminal cover is standard equipment.
![Open/close type small terminal cover + wire marker sleeve insulation provides good finger protection (IP20 supported from front direction [TÜV-certified]). Added finger protection from the direction of cable insertion.](http://th.misumi-ec.com/en/linked/vitem/el/MID1/222000347909/img/222000347909_jh_w02.jpg)
Open/close type small terminal cover + wire marker sleeve insulation provides good finger protection (IP20 supported from front direction [TÜV-certified]). Added finger protection from the direction of cable insertion.

Can open and close with a single action, making terminal check easy when shipping panels or when performing initial inspection.
Easy to check terminals during maintenance.

Even if the terminal cover is closed, the wire marker sleeve symbol is not hidden and can be checked at a glance.

Insulation resistance measurement and energization inspection are possible even when the terminal cover is closed.
Type for Both AC and DC Use
Type for both AC and DC use. Can be used as is for circuits not more than 250 V AC and 65 V DC.
Space Saving
- Compact, with an extremely thin width of 17.5 mm per pole.
- Greatly contributes to space saving, particularly when using a large quantity.
