Project Description

LP1-D DC contactor

Introduction

AC contactor is widely used in power transmission system. Applicable to long-distance frequent switching on and switching end DC main circuit and large capacity control circuit in, it main control object is all motor, and can also be used for electric welder control, capacitor banks, and the electric heating device, lighting equipment and other loads. For example, power industry, industrial and mining enterprises, iron and steel plants, and some large power will use it. Can also cooperate with the fuse, the dynamic air circuit breaker, thermal relay and other electrical use, in order to better protect the line current.

An air conditioning unit is a complex system of electronic components that must work together so that your AC system can run at the right times.

Why do we need to use AC contactor?

We live around a lot of large equipment to start the knife gate will have a spark, arc, will have a security risk, if it is safe to contact the remote control is much more safe.

Can also cooperate with the fuse, the dynamic air circuit breaker, thermal relay and other electrical use, in order to better protect the line current.

Its advantages: it has a large number of control, the action is rapid, safe and easy operation, etc., and has the function of under voltage release, the application is very extensive in industrial and agricultural production. Simple wiring. The contact point of the AC contactor is made of silver tungsten alloy, which has good electrical conductivity and high temperature resistance. Can prolong the service life of the switch, protect the electric equipment.
