Low-voltage Power Distribution Products
MOLDED CASE CIRCUIT BREAKERS NV
Reduce the risk of malfunction
Wide assorted products which is suitable for protections of an overload, a short circuit and an electric shock in low voltage circuit. Our earth leakage breakers have characteristics (DPDC surge discrimination circuits) that reduce the risk of malfunction due to harmonics or surges. Furthermore, the CE compliant and UL listed NV devices at 250A or below have Type A electrical leakage characteristics.
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.)
