Custom Miniature 4 Pole Molded Case Circuit Breaker 300A 350A 400A

 

 

UKM30L Series Earth Leakage Circuit Breaker is developed with hi-tech in 1990S with completed protection functions, high performance, smart dimension which is the ideal replacements for the olds.

 

 

Description:

 

The ELCB′s electric leakage(residual current) protection function offers indirect touch protection when person gets an deadly electric shock. It also can prevent the electrical fire as a result of over-current protection device which can′t  detect the earthing fault.The ELCB′s  rated residual operating current can be adjusted, electric leakage protection operating time also can be adjust, so it has selective protection in power distribution system.When the rated residual operating current is set up as 30mA, and the relevant protection device was failed,it also has the protection function of direct contact.

Purpose:

 

The main purpose of earth leakage protectors is to prevent injury to humans and animals due to electric shock.

 

 

 

Operation:

 

An ELCB is a specialised type of latching relay that has a building's incoming mains power connected through its switching contacts so that the ELCB disconnects the power in an earth leakage (unsafe) condition.

The ELCB detects fault currents from live to the earth (ground) wire within the installation it protects. If sufficient voltage appears across the ELCB's sense coil, it will switch off the power, and remain off until manually reset. A voltage-sensing ELCB does not sense fault currents from live to any other earthed body.
