[DC contactor]CCZ35 series DC contactor

2026-4-24 10:16:17

CCZ35-200/10 DC contactor is suitable for remote connection, disconnection or reverse connection of brake oil pump DC motor in electronic control systems with rated working voltage of 12-24V and rated working current of 200A. This product is designed for short-term operation, with natural arc extinguishing and zero arcing distance. In the process of automatic control, the contactor control circuit controls the rated control voltage of the contactor coil through the relay in the control current, so as to generate or eliminate electromagnetic force in the magnetic system of the contactor. The armature drives the main contact to connect or disconnect the circuit under the action of electromagnetic force.

The CCZ35 series DC contactor has the following characteristics:
1. Natural arc extinguishing, zero arc spraying distance. The design of the reaction force spring and the contact spring is in a straight line, so that the reaction force and the main force do not produce a force component, which improves the breaking speed, greatly shortens the residence time of the arc on the contact, and avoids the phenomenon of contact burnout.
2. The main circuit inlet and outlet terminals are designed to be integrated with the static contacts, solving the problem of main circuit heating caused by fastener connection or welding.
3. The integrated design of the input and output wire connectors of the electromagnetic coil and the skeleton eliminates the error of manual welding.
4. Small size, light weight, and easy disassembly.

1�� Scope of application
The CZ0 series DC contactor (hereinafter referred to as the contactor) is mainly used for frequent connection and disconnection of DC circuits over long distances, such as controlling DC motors.

3�� Structural features
The rated operating frequency of contactors with normally open main contacts of CZ0-150 and below is 1200/hour, with a mechanical life of 5 million cycles and an electrical life of 500000 cycles.
The rated operating frequency of CZ0-150 and below contactors with normally closed main contacts and CZ0-250 and above contactors is 600 times/hour, with a mechanical life of 3 million times and an electrical life of 300000 times.
The critical breaking capacity of the main contact of the contactor at rated voltage is 0.2 times the rated current. Therefore, when using it, be careful not to reduce the working current too much. For CZ0-40, in order to ensure reliable arc extinguishing when breaking small currents, the rated current of its arc extinguishing coil is divided into six types: 1.5, 2.5, 5, 10, 20, and 40A, for selection.
The breaking capacity of the main contact of the contactor at rated voltage and the distance of the arc beyond the arc extinguishing chamber are shown in Figure 1, Figure 2, and Table 1.
5. The thermal stability of the contactor can withstand 7 times the rated current for 10 seconds, and the dynamic stability can withstand 20 times the rated current.
6. The parameters of the contactor are shown in Figure 3, Figure 4, and Table 2.
7. For contactors with series connected double winding attraction coils (which have three terminals A, B, and C), their control power must be connected to both ends of A and B, otherwise the coils will be burned.
