Product Description

DAM11 Series Moulded-case Circuit Breaker
Product overview

DAM11, DAM11LY, DAM11RT, DAM11E and DAM11EL series of circuit breakers are new upgraded circuit breakers researched and developed by the company combined with the advantages of similar international products and demand of domestic and international markets.
With insulation voltage up to 1000V, the circuit breaker is applicable for distribution systems of AC50Hz, rated working voltage 690V and rated working current from 10A to 800A, used to distribute electric power energy, protect circuits and power equipment against overload, short circuit, under voltage and so on, also can be used for infrequent startup of motor and protect it from overload, short circuit or under voltage.
It is featured with small size, high breaking, short flashover, etc., is the ideal product for users. It can be vertically installed or horizontally installed.
DAM11DC series DC moulded-case circuit breaker (hereinafter referred to as circuit breaker) is suitable for DC systems of rated voltage up to and including DC 1000V and rated current 10~800A, used to distribute electric power energy, protect circuits and power equipment against overload, short circuit and so on.
The products can be fed with wires from top and bottom, and it is polarity-free.
It complies with the standards IEC60947-2, GB14048.2, etc.
Ambient and installation conditions

 Altitude up to 2000m;
 Ambient medium temperature should be within -5ºC to +40ºC (+45ºC for marine products);
 It can withstand the effect of damp air;
 It can withstand the effect of moulds;
 It can withstand the effect of nuclear radiation;
 The max inclination is 22.5ºC.
 It still can work reliably when the ship subjects to normal vibration;
 t 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.
