Better Performances in Demanding Duties

YEM1L series moulded case earth leakage circuit breaker is applied in the circuit of AC 50/60HZ,.It is used to transfer infrequently and protect motor. Circuit breaker has over-load,short circuit and under-voltage protection function so that protects the circuit and power supply device from being damaged. At the same time,it can provide indirect contact protection for people, and it can also provide protection for fire rise which may be caused long-term ground faults that cannot be detected by over-current protection. When other protective devices fail, the leakage current circuit breaker YEM1L with a rated residual current of 30mA can directly act as an additional protection.
Product advantage
1.This circuit breaker can be equipped with leakage alarm and non tripping module to avoid heavy losses caused by power failure.
2.This circuit breaker has the features of small volume,high breaking ability,short arc and anti-vibration.
3.Circuit breaker can be installed in a vertical way.
4.The circuit breaker can not be poured into the line,that is only the 1、3、5 is allowed to connect the power line,and the 2、4、6 is connected to the load line.
5.Circuit breaker has isolation function.

1.This series products all could using together with Y-700,Y-701,Y-702 series PC class Automatic transfer switch controller,except NA,SA,LA type products.
2.The instruction of ATS controller,please see details “PC class Automatic transfer switch controller”.

Product feature
YES1 series ATSE consists of switch body and transfer control these two parts. Switch is driven by electromagnetic coil,so the transfer speed is very fast. The power source of controller takes main power or emergency power AC220V as working voltage.

NA,SA,LA type ATSE is integral type. The controller is installed inside of switch body. User only need to connect the main circuit then ATSE could work. It’s convenience for user connect writing. Meanwhile,SA type ATSE with generator start signal,passive fire input,passive fire feedback,main power and emergency power closing indicator.

N,C,M,Q,S,L is split type. The controller is separated with switch body. User should connect controller with switch body by wires.
Integral and split type ATSE both with over voltage,under voltage,default phase etc fault detection function and also with generator start and stop signal output function(When main power fault,the signal will be sent out after 3s time delay. When main power recover,the signal will be stopped after 3s time delay).

Structure and features
YEQ1 series Automatic Transfer Switch,is composite by 2PCs 3P or 4P mini circuit breaker,mechanical chain transmission mechanism,controller,etc,the feature will be as follows:
1.Small in volume, simple in constitution; there is provide 3P,4P. easy to operation and long to use.
2.Transfer switch driving by single motor,a smooth,no noise,the impact is small.
3.With mechanical interlocking and electrical interlock,change over credibility,could be supply by manual or automatic operation.
4.Have the short circuit,overload protection also the over voltage,under voltage,loss phase function and also the intelligent alarm function.
5.Automatic switching parameters can be freely outside.
6.With computer network interface for remote control,remote adjustment and remote communication,remote sensing and other four control function and so on.

Working conditions
1.Ambient air temperature of -5℃ to +40℃,and at 24 hour average temperature does not exceed +35℃.
2.The installation location no more than 2000 meters.
3.The maximum temperature of +40℃，the air relative humidity is no more than 50%,at a low temperature can be allowed to have a higher relative humidity,such as 20℃ at 90%. special measures should be taken for occasional condensation due to temperature changes.
4.Pollution level:grade Ⅲ
5.Installation category:Ⅲ.
6.The two power lines are connected to the upper side of the switch,and the load line is connected to the lower side.
7.The location of installation should not have significant vibration,impact.
