Product Description
Modules case circuit breaker
Modules case circuit breaker is one of the new type circuit breakers researched and developed by our company adopting international advanced design and manufacturing technologies. It is rated insulation is 690v, is suitable for circuitries of AC 50Hz, rated working voltage up to and including 690v. And working current up to 800A, used for infrequent changeover as well as motor’s infrequent start up. This circuit breaker has protective functions against overload, short-circuit or under-voltage. It protects the circuitries and power equipment from being damage.
The products are featured with compact volume, high breaking capacity short flash-over, vibration proof, etc. It really is the ideal products for land and marine purpose.
The circuit breakers can be installed either in vertical or in horizontal
The circuit breaker has the isolation function.
The circuit breakers are in accordance with standards.
Main features
Rated insulation voltage 690v
Frame size rated current 63A, 100A, 225A, 400A, 630A, 800A
High breaking capacity as high as 100KA
Reasonable design safe and reliable performance compact volume, light weight elegant appearance.
Complete accessories, convenient installation, easy use, wide applicability.
Residual current three phase protection: the working power sampling of leakage protection module for conventional residual current protection breaker is two phase. This series breaker is three phase and if lose any one phase the leakage protection module still can work normally.
Field adjustment the rated residual operating current and the residual current operating time can be adjusted according to the actual situation.
Low voltage protection: when the phase voltage is as low as 85v, the leakage protection module still can working normally.
Leakage alarm output function: when the residual current of equipment of circuitry reaches or exceeds the setting value, the circuit breaker with leakage alarm module would output a passive contact signal to drive corresponding alarm devices.
Working environment and installation conditions:
Altitude: ≤2000m
Ambient medium temperature should be within -5℃ to +40℃
Pollution class:Ⅲ
It can withstand the effort of salt mist or oil mist
It can withstand the effort of damp air.
It can withstand the effort of molds
The max inclination is ±22.5℃
It still can work reliable when the ship subject to normal vibration
The surrounding medium should be free from explosion danger, the installation site should be far away from gas or conductive dust that would erode the metal or destroy the insulation.
Keep away from rain or snow.
