AOMR-160-3P/4P Thermomagnetic Adjustable

AOMR

Characteristics

AOM, AOML, AOMR and AOME, AOMEL 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, undervoltage and so on, also can be used for infrequent startup of motor and protect it from overload, short circuit or undervoltage.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.

Product features:

Feature 1: U-shaped static contact

Feature 2: modularized accessories

Feature 3: miniaturized frame

Feature 4: contact repulsion device (patented technology)

Feature 5: intelligence

Feature6: modularized arc extinguishing system

Feature 7: unification


Ambient and installation conditions:

● Below 2000 meters above sea level;

● Ambient medium temperature should be within -5℃to +40℃(+45℃for marine products);

● lt can withstand the effect of damp air;

● lt can withstand the effect of moulds;

● lt can withstand the effect of nuclear radiation;

● The max inclination is 22.5 degree;

● lt still can work reliably when the ship subjects to normal vibration;

● lt can still work reliably if the product subjects to the earthquake (4g).

● Places where the surrounding medium is free from explosion danger, and far awayfrom gas or conductive dust that would erode the metal or destroy the insulation;

● keep away from rain or snow.
