Product Overview

A. CFH-125 ARD PV over and under voltage automatic

Reclosing circuit breakers (hereinafter referred to as circuit breakers) meet standards:

IEC60898-1《Electrical accessories for household use and similar places Over-current protection circuit breakers - Part 1: circuit breakers for alternating current》.

B. The circuit breaker is suitable for AC50Hz, rated power Voltage 230V(1P+N, 2P), 400V(3P+N, 4P).

Automatic intelligent closing when power circuit operating ,

Automatic break, in the case of power failure and at the same time offer protection of overload and short circuit .

It can also be used as infrequent operation of the line under normal conditions, It is widely used in the intelligent transformation of power grid.

C. The front of the product is provided with a green signal indicator light and the main circuit

The indicator light keeps on when there is electricity; Main circuit power failure The lower indicator is off.

D.Automatic brake opening in case of power failure ( after power failure Manual Operating handle cannot lose).

Check before installation

A. After unpacking, check whether the circuit breaker is intact. Whether the wiring terminal is rusted, whether the wiring board is seriously oxidized, for example

Please contact the supplier in time.

B.Close and open the circuit breaker with ease.

Installation and reliable connection of circuit breaker

A. During installation, clamp the circuit breaker directly to TH35-7.5
Install the guide rail until you hear the "click" sound.
B. When disassembling, turn all bottom restraint parts outward with tools
Pull about 5mm until you hear the "click" and remove the circuit breaker.
C.Use a cross screwdriver to fix the wire to the wiring socket.For conductor selection see 7.

Mounting dimensions

Check

A. After the circuit breaker is installed, check whether the cables are correctly connected After confirm connecting correct then close the circuit breaker, when power failured ,manual operation levers cannot close.
B. The circuit breaker meets the following functions:
1. Rated working voltage AC230V;
2. Over-voltage action cut-off value: A300V±5V;
3. Over-voltage recovery value: AC260V±5V;
4. Under-voltage action cut-off value: AC44V-160V;
5. Under-voltage recovery value: AC196V±5V;
6. Delay of power supply after power failure: > 5s;
7. Action delay time: > 5s;
8. Automatically cut off after no-voltage .

Announcements
