Considering the condensation occurring on the surface of the product due to temperature changes.
Installation Conditions	Installed in places without significant shaking and shock vibration, the magnetic field near the installation site should not exceed 5 limes of the magnetic field in any direction, and leakage circuit breakers should generally be installed vertically.
Installation	Circuit breaker can be installed vertically (i.e. vertically) or horizontally (i.e. horizontally).
Input mode	Circuit breaker can't go down, that is, only 1,3,5 power lines, 2,4,6 load lines

 

AISIKAI MCCB molded case circuit breaker is a new type of the circuit breaker that the company has designed and developed through adoption of a combination of international advanced technologies. 

Circuit breaker with overload, short circuit and under voltage protection device to protect the power lines and equipment from damage.

The circuit breaker can be installed vertically (ie, vertical loading), or horizontally (ie, cross-loaded).

According to the level of its rated ultimate short circuit breaking capacity, it is divided into three categories, namely L type(standard type), M type(comparatively high breaking type),H type(high breaking type),the product is small volume, high breaking capacity, short arcing and anti-vibration characteristics,it is ideal for land and marine use.

Rated insulation voltage 800V,suitable for AC 50HZ, rated working voltage 690V and below the circuit for infrequent start with.
