QM1E Electronic adjustable type MCCB


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.


Product 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.
● QM1EL series is circuit breaker with residual current protection function.


Panel and function description
Intelligent release panel

Panel adjustment knob as follows in turn:

● IR(A) Isd(x IR) Ii(x IR)
● IR: Overload long delay tripping setting current; Isd: Short-circuit short delay tripping setting current;
● Ii: Short-circuit instantaneous tripping setting current;

The rest parameters are set by factory default, or set by remote communication, as follows:

● tR: Overload long delay setting time, factory default: 60s;
● tsd: Short-circuit short delay setting time, factory default: 0.1s;
● Ip: Overload pre-alarm setting current, factory default: 0.85*IR;

Panel With Residual Current Protection

1: Setting current In overload indicator, the red light will go on when the operation current is ≥ 105% InQM1E Electronic adjustable type MCCBQM1E Electronic adjustable type MCCB
2: Pre-alarm current Ip indicator, the yellow light starts flashing when operation current is ≥ Ipx90%
3: When operation current is ≥ 60% xln setting current, the green light will go on
4: The code switch for residual current setting
5: The code switch for leakage action time setting
