Structural characteristics

1: The contactor has the characteristics of small size, light weight, low power consumption, long life, safety and reliability.

2: Auxiliary contact groups, air delay heads, thermal relays and other accessories can be installed in a building block installation manner to form a variety of derivative products.

3: The contactor body has one pair of normally open or one pair of normally closed auxiliary contacts for 32A and below, and one pair of normally open and one pair of normally closed auxiliary contacts for 40A and above. In addition, F4 auxiliary contact groups (two or four groups) or F5 air delay contacts can be installed on the top.

4: In addition to installing the contactor with screws, CQC5-09A~32A can be installed with 35mm standard rails; CQC5-40A-95A can be installed with 35mm or 75mm standard rails.
