Circuit Protectors

A circuit protector is a circuit breaker that has a function to protect load equipment against overcurrent. Used for overcurrent protection of control panels and overcurrent of power supplies such as communication equipment, OA equipment, etc. Of the safety functions built into control panels and switchboards, the purpose is to protect electrical equipment from electrical circuits, and is used to protect low-capacity control circuits, motors, electronic circuits, etc. that are not protected by wiring breakers (MCCB). Switches with a switch function can actively cut off load current, and circuit protectors may be used as power switches for small-capacity devices. There are also trip-free structures and those with an alarm switch. When selecting a product, check whether it is AC / DC compatible or dedicated, rated current, number of poles, overcurrent operation characteristics, etc.

NC1V Circuit Protector

IDEC

The main circuit terminal IDEC uses its own "SS terminal". Easy to use and safe.

[Features]
· With the electric shock protection structure integrated into the main body, the main circuit terminal part can achieve IP20. It is unnecessary to order another terminal cover or do retrofitting.
· Terminal cover is standard equipped with auxiliary contact and alarm contact, relay trip type.
· With the "SS terminal", man-hours for wiring can be drastically reduced. With the upward screwing structure of the "SS terminal", it is easy to install the round crimp terminal. Since removing screws is unnecessary, you don't need to worry about losing screws.
· Selectable with inertia delay (inertia delay mechanism).
· Includes auxiliary contact, selectable with alarm contact.
· Rated breaking current: 2, 500A.
· Slim and space saving. 1 pole: width 17.5 mm, 2 pole: width 35.0 mm, 3 pole: width 52.5 mm.
· Flat handle shape.
· Due to the trip-free structure, even if you accidentally turn the handle to the on position during a bad circuit state, the circuit will still be shut off.
