NC1V Circuit Protector
Caution
Product Description
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.

*1) 3-position type is dedicated for AC.
*2) When the instantaneous (S) type is used with AC (sine waveform circuit), a buzzing noise may be generated when it reaches around 80% or more of the rated current value. There is no problem in performance. Therefore, consider this point when selecting for use in a quiet environment. Also, to prevent unnecessary operation, do not use in a circuit that generates inrush current.
*3) Relay trip type (voltage tripping) has no overcurrent tripping function.
* Do not use in environments where temperature, humidity, dust, corrosive gas, vibration, shock, etc., exist abnormally, or in circuits that generate inrush current. There is a risk of unnecessary operation and failure.
