Low-voltage Power Distribution Products
MOLDED CASE CIRCUIT BREAKERS AE-SW
The main circuit breaker for buildings and factories
The air circuit breakers are ideal as a main circuit breaker and realize the advancement of power distribution equipment.The air circuit breaker has a wide characteristics adjustment width, high performance operating durability and a high rated short-time current carrying capacity and has a variety of accessories available.
It is therefore used widely as the main circuit breaker for buildings and factories and as the breaker for marine vessels.
Types of Low-voltage Circuit Breakers
The following IEC
Standards apply to low-voltage circuit breakers.
There are multiple product standards for the same type of device.
The standards system applies to industrial use (a skilled person handling the device)
and household use (a person handling device has no experience.)
