CQC5 AC Contactor with Overload Protection

The CQC5 series AC contactor, meticulously designed by CHAC Electric, is a highly versatile and reliable solution for industrial electrical systems. Engineered for AC 50Hz systems with a rated working voltage up to 660V, it delivers exceptional performance in the AC-3 usage category, handling a working current up to 95A at a rated voltage of 380V. This makes it an ideal choice for remotely connecting and disconnecting circuits, as well as for the frequent starting and control of AC motors.

Overview and applications

1.Broad voltage compatibility

2.High-performance switching

3.Compatible with thermal overload relays to form electromagnetic starters, protecting against overload and phase failure

4.Designed for high-duty-cycle industrial motor control and circuit protection

Product Overview

The contactor can be integrated with suitable thermal overload relays to form magnetic starters, offering comprehensive protection for circuits prone to operational overloads and phase breaks. By meeting the stringent GB/T 14048.4 standard, the CQC5 series ensures durable and faultless operation, even in demanding industrial environments. Its advanced design and superior build quality make it a trusted component in motor control applications, providing long-term reliability and safety.

8.Shock and vibration: The product should be installed and used in a place without significant shaking, shock and vibration.

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.
