Product Description
Applicable range
M1L series residual current circuit breakers (hereinafter called circuit breaker)are applied for the power distribution network of AC50Hz / 60Hz, rated voltage 400V and rated current up to 800A. They can protect people against indirect contact and prevent fire disaster caused by insulation and ground fault. They can also be used to distribute electric power and protect power equipment against overload and short current, and can change the circuit and start motor infrequently.
According to the actual situation ,the rated residual operating current IΔn and residual current operating time can be locally adjusted;The creepage protection module still normally operate and creepage alarm output function, even if the phase voltage reduces to 50V.
Comply with the demands of the following standards:IEC60947-2 and GB14048.2
Structure and operation principle
Structure
This serial circuit breakers are electronic protective devices of electric leakage of electric current movement. Main parts are as
follow: main switch(containing overcurrent release), zero-sequence transformer, electronic amplifier, leakage release, experimental
rig, all spare parts are put on a plastic shell.
Operation principle
when there are electric leakage or shock in the protected circuit, zero-sequence transformer outputs a signal, which up to a certain
value, it can make silicon controlled rectifier open, then make leakage release move, thus drive the traction lever, which may cut off the
power in short time. And it realizes the function of protecting electric leakage.
