Features

     The product is of novel structure and small volume, in the width of 18mm there are two poles. Compared with ordinary industrial AC contactor; it is much smaller in volume, and it is a modularized terminal electric appliances. The product can be assembled with miniature circuit breaker to be installed in controlling or illumination cabinet.
     Adopting insulation material with good performance greatly enhances the security of the products. With elegant appearance, and there is installation sketch map of the product for customer's convenience.
