The following are the data of the CJX2 - 1801 AC contactor:
Electrical Parameters
- Rated Insulation Voltage: 690V. This determines the maximum voltage the contactor can withstand, ensuring insulation safety.
- Conventional Thermal Current: Generally 25A. It refers to the maximum current that the electrical appliance can carry under the specified test conditions during an 8 - hour duty cycle, with the temperature rise of each component not exceeding the limit value.
- Rated Operating Current (400V AC - 3): 18A. It is applicable when controlling loads such as motors. Under the AC - 3 utilization category (commonly used for starting and interrupting in the operation of three - phase squirrel - cage asynchronous motors) and a rated operating voltage of 400V, this is the normal operating current value.
- Control Capacity: It varies with different voltages. For example, at 400V, it is approximately 11kW (corresponding to the rated operating current of 18A).
- Coil Voltage: Commonly available options include AC36V and others. Different voltage specifications meet the requirements of different control circuits.
- Coil Frequency: 50Hz or 60Hz, adapting to different power supply frequency environments.
Contact Parameters
- Number and State of Main Contacts: 3 normally open (3NO), used for connecting and disconnecting the main circuit.
- Number and State of Auxiliary Contacts: 1 normally closed (1NC), which can be used in the control circuit to achieve interlocking, signal feedback, and other functions.
Mechanical and Electrical Lifespan
- Mechanical Lifespan: Up to 10 million times. It refers to the number of no - load operations the contactor can withstand without the need for repair or replacement of mechanical parts.
- Electrical Lifespan: Up to 1 million times. It refers to the number of normal live - circuit operations of the contactor under specified conditions.
Structure and Installation
- Structural Features: It is of the protective type, with a direct - acting operating structure and double - break contacts. It has the characteristics of small size, light weight, low power consumption, long lifespan, safety, and reliability. It adopts a modular assembly method, and additional accessories can be conveniently installed on the five surfaces except the mounting surface.
- Installation Methods: It can be installed using a 35mm standard rail, a 75mm standard rail, or by screws.
