AOMR-630-3P/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
