CMK663 3 Circuit Lever Wire Connector for Flexible Electrical Connections
TheJINH CMK663 is a 3 circuit lever wire connector developed for electrical installations that require convenient wiring, flexible connection, and organized circuit management.
As a member of the JINH CMK66 series, CMK663 combines a lever-operated wiring mechanism with a pluggable connection structure. This combination provides installers with a practical alternative to conventional fixed wiring methods.
The three-circuit configuration allows multiple conductors to be managed through one compact connector. It is suitable for applications where several electrical connections need to be arranged in a limited installation area.
With a rated voltage of 600V and rated current of 41A, CMK663 is designed for a wide range of electrical equipment and wiring applications.
The connector can be used in lighting equipment, control cabinets, automation systems, machinery, electrical appliances, and industrial installations.
Three Circuit Design for Organized Wiring
CMK663 provides 3 independent connection circuits within one connector.
When several wires need to be connected in the same area, using individual connectors for every connection can increase the number of components and make wiring management more complicated.
The three-circuit design of CMK663 allows multiple connection points to be arranged together.
This can help installers:
- Organize multiple conductors
- Reduce the number of separate connectors
- Make wiring layouts easier to manage
- Save installation space
- Simplify maintenance
- Improve assembly efficiency
The three-circuit configuration provides a balance between compact size and multi-wire connection capacity.
Lever Wire Connection for Faster Installation
One of the main features of CMK663 is its lever-operated wiring mechanism.
The orange levers provide a simple way to control the connection points.
During installation, the operator can open the corresponding lever, insert the conductor, and close the lever to complete the connection.
This operating method can reduce the need for repeated screw tightening and make wiring work more convenient.
The lever mechanism is especially useful during:
- Initial installation
- Electrical equipment assembly
- Wiring adjustment
- Routine inspection
- Component replacement
- Equipment maintenance
Because each connection position can be operated separately, technicians can work on the required circuit without unnecessarily disturbing other connections.
Pluggable Connection for Flexible Equipment Assembly
In addition to lever wiring, CMK663 features a pluggable connection structure.
The detachable connection design can be useful when electrical modules need to be installed, removed, replaced, or serviced.
For equipment manufacturers, the pluggable structure can simplify assembly procedures.
For electrical installers, it provides additional flexibility during installation and maintenance.
This makes CMK663 suitable for equipment that may require regular inspection or modular replacement.
600V and 41A Electrical Rating
CMK663 is designed with the following electrical ratings:
Rated Voltage: 600V
Rated Current: 41A
These specifications make the connector suitable for a variety of electrical applications where higher voltage and current capacity are required.
The actual application should always be evaluated according to the complete electrical system, conductor size, ambient conditions, load requirements, and relevant standards.
Wide Wire Compatibility
CMK663 supports both flexible and rigid conductors.
Flexible Wire
0.2–4mm²
Rigid Wire
0.2–6mm²
This wire range allows the connector to be used with different conductor types and sizes.
The recommended stripping length is:
11mm / 0.43 inch
Following the recommended stripping length helps ensure that the conductor is correctly positioned inside the terminal.
Transparent Polycarbonate Housing
The housing of CMK663 is made from transparent polycarbonate.
The transparent shell provides visibility of the internal connection area, which can make installation and inspection more convenient.
Users can more easily check conductor positioning after installation without immediately removing the connector.
Polycarbonate is widely used in electrical components because of its useful mechanical properties and dimensional stability.
The transparent housing also gives CMK663 a clean appearance and makes the internal connection structure easier to identify.
Polyamide Operating Levers
The operating levers are made from Polyamide.
The orange lever design provides a clearly visible operating point for installers.
During wiring work, the lever can be repeatedly opened and closed as needed for connection adjustment and maintenance.
The visible lever structure can also make the connector easier to operate when multiple electrical components are installed inside a control cabinet or equipment enclosure.
Tinned Copper Conductive Parts
CMK663 uses tinned copper conductive parts for the internal electrical connection.
Copper offers good electrical conductivity, while tin plating can help protect the conductive surface against oxidation.
The conductive components work together with the contact springs to establish the electrical path between the inserted conductors.
This material combination is suitable for electrical connector applications where stable conductivity and practical long-term use are important.
AISI 301 Stainless Steel Contact Springs
The internal contact springs are made from AISI 301 stainless steel.
The springs provide the contact force required to hold the conductor securely within the connection area.
AISI 301 stainless steel is commonly used for spring components because of its mechanical strength and spring characteristics.
The contact springs work together with the lever and conductive components to form the complete connection mechanism.
Working Temperature: -40°C to 105°C
CMK663 has a specified working temperature range of:
-40°C to 105°C
This broad temperature range allows the connector to be considered for different electrical equipment and installation environments.
When selecting the connector for a specific project, users should also consider ambient temperature, electrical load, enclosure conditions, installation method, and applicable electrical standards.
