Characteristics of the structure
It can be assembled with auxiliary contact set, air delay head, thermal relay and other accessories by block mounting method, and combined into a variety of derived products.
AC contactor has the characteristics of small size, light weight, low power consumption, high life, safety and reliability.
The contactor body has a pair of normally open or normally closed auxiliary contacts by default for 32A and below, a pair of normally open and normally closed auxiliary contacts for 40A and above, and the product body does not have auxiliary contacts for 115A and above, and F4, F8 auxiliary contacts or air delay head and other accessories can be added.
In addition to screw mounting, AC contactors can also be mounted with 35mm [CJX2-09 ~ 95], 75mm [CJX2-40 ~ 95] and 2*35mm [CJX2-115 ~ 170] standard clamp rails
