Product Description

 

 

 

Earth Leakage Circuit Breaker - ELCB

Prouduct Description:

Rated current In(A): 250, 300, 350, 400,

Number of poles: 3, 4

Rated voltage Ue(V): AC690

Arc distance(mm): 0

Rated limit short capitily lcu/lcs(KA): 50/25

Rated residual actuation: 1/2LΔ N

Rated residual short capitily lcu/lcs(KA): 1/4lcu

Rated residual operation current (non delay): 30mA, 300mA, 500mA (adjustable)



The Earth Leakage Circuit Breaker can be used in the electric power system of AC 50Hz, rated voltage up to 400V, rated current up to 400A for the distribution of power, protection against faults such as overload, short circuit, Leakage etc. As well as control of infrequent operation of motor.

For the function of protection against leakage (of residual current), this Earth Leakage Circuit Breaker can indirectly protect people against the fatal danger of getting electric shock. It can also prevent from fire disaster due to permanently existing ground fault but not being checked up with overcurrent protection device.

For both rated value of residual action current and leakage protection actuation time are adjustable, the breaker can be used in the power distribution system serving as optional protection when leakage occurs.

The CEarth Leakage Circuit Breaker can also serve as protection unit against direct contact when rated residual current is set at 30mA and the relevant protection unit doesn't work.
