YCB3  Mini Circuit Breaker MCB  

 General

        YCB3(DPN) is applicable to protect line-conductor against overload, and short circuit of small sealed  motors. It is main for protection of circuits with AC 220V and 50Hz/60Hz, and for unfrequent conversion under normal conditions as well. Its action can be  up to two poles with its only one pole volume and  be used as a leakage breaker by assembling with leakage. It is produced as IEC60898.

Working condition:

1.The ambient temperature should not be higher than +40C and not lower than -5C and the average temp. of 24 hours should not exceed +35C

2.The altitude should not higher than 2000m

3.The atmospheric relative humidity should not exceed 50% when the highest ambient temperature is +40C,higher humidity maybe allowed at lower temperature.Take measures to solve the dews on the breakers caused by the temperature variation.

4.Pollution grade:2

5.Installation type:II and III,controller and auxiliary circuit

Structure feature

          YCB3(DPN) miniature circuit breaker has compact structure in the width of 18mm,it has two pole (P+N),which is specially suitable for household and derive leakage circuit breaker.The insulation case is installed with contact system,arching-extinguish system,sour-link rapid move framework and thermal-electromagnetic release,which is released to different trip current.
