Product overview

YOM6E and YOM6EL series electronic circuit breakers are applicable for low-voltage power systems of AC 50Hz, rated operating voltage up to 1000V and rated operating current from 16A to 800A.

Ambient and installation conditions

◆Altitude up to 2000m;
◆Ambient medium temperature should be within -5℃ to +40℃ (+45℃ for marine products);
◆It can withstand the effect of damp air;
◆It can withstand the effect of salt fog or oil mist;
◆It can withstand the effect of moulds;
◆It can withstand the effect of nuclear radiation;
◆The max inclination is 22.5℃.
◆It still can work reliably when the ship subjects to normal vibration;
◆It can still work reliably if the product subjects to the earthquake (4g).
◆Places where the surrounding medium is free from explosion danger, and far away from gas or conductive dust that would erode the metal or destroy the insulation;
◆Keep away from rain or snow.

Features

◆Circuit breaker can be equipped with undervoltage release, shunt release, auxiliary contacts, alarm contacts, electric operating mechanism, rotary operating handle and other accessories.
◆Circuit breaker has protection functions of overload long delay, short-circuit short delay and short-circuit instantaneous protection, the user can set the required protection characteristics (user only needs to operate the DIP switch for settings of protection function parameters).
◆Circuit breaker has ground fault and thermal analog protection functions, pre-alarm indication over-current indication, load current indication, digital current analysis technology, and it can achieve a higher level of protection.
◆YOM6EL series is circuit breaker with residual current protection function.
