Each orange lever controls an individual connection point, providing flexibility during installation, inspection, and maintenance.
With its multi-circuit design, durable materials, and wide wire compatibility, CMK425 is suitable for residential, commercial, and industrial electrical applications where organized and efficient wiring is required.
Five Circuit Design for Multiple Wire Connections
CMK425 features a five circuit connection structure designed for applications requiring multiple electrical connections in a limited installation space.
Compared with CMK401, CMK422, CMK423, and CMK424 models, CMK425 provides the highest circuit capacity in the CMK42 series.
The five-circuit design allows multiple conductors to be connected within a single compact connector, helping reduce the number of separate connection components required.
This structure improves wiring organization and provides a cleaner installation layout.
Typical applications include:
- LED lighting systems
- Electrical distribution wiring
- Junction boxes
- Control cabinets
- Automation equipment
- Industrial electrical systems
- Equipment internal wiring
For projects requiring multiple connection points, CMK425 provides an efficient and practical wiring solution.
Multi Circuit Wire Connector for Organized Wiring
Modern electrical systems often involve multiple connection points and complex wiring arrangements.
CMK425 is designed as a multi circuit wire connector to simplify these applications.
By combining five independent circuits into one connector body, CMK425 helps installers manage multiple wires more efficiently.
The compact structure reduces installation space requirements compared with using several individual connectors.
This makes CMK425 suitable for:
- Electrical enclosures
- Control systems
- Equipment manufacturing
- Lighting projects
- Building electrical installations
The organized connection design helps improve wiring clarity and makes future maintenance more convenient.
Lever Connection Structure for Easy Installation
CMK425 uses a practical lever-operated connection system.
Each circuit has an independent orange operating lever.
During installation:
- Open the lever
- Insert the prepared conductor
- Close the lever to complete the connection
This tool-free operation helps improve wiring efficiency and reduces installation steps.
Compared with traditional screw terminal blocks, the lever structure eliminates repeated screw tightening and provides easier access during maintenance.
The independent lever design also allows users to inspect or replace individual wires without affecting other circuits.
Transparent PC Housing for Better Visibility
The CMK425 housing is made from Polycarbonate PC material.
The transparent housing design allows installers to visually inspect the internal conductor position after installation.
This helps confirm whether wires are properly inserted and positioned.
PC material provides:
- Good mechanical strength
- High durability
- Reliable protection for internal components
The transparent structure improves installation accuracy while maintaining a compact and professional appearance.
Reliable Materials for Long-Term Electrical Performance
CMK425 uses high-quality materials to ensure stable electrical performance.
PA66 Operating Lever
The operating levers are manufactured from Polyamide PA66.
PA66 provides good mechanical strength and durability, supporting repeated operation during installation and maintenance.
Tinned Copper Conductive Parts
The conductive components use tinned copper.
Copper provides excellent electrical conductivity, while tin plating improves corrosion resistance and helps maintain long-term connection reliability.
AISI 301 Stainless Steel Contact Spring
The contact springs are made from AISI 301 stainless steel.
The stainless steel spring maintains consistent contact pressure, ensuring stable electrical connections during long-term operation.
The combination of PC housing, PA66 levers, tinned copper conductors, and stainless steel springs creates a durable electrical connection structure.
Wide Wire Compatibility
CMK425 supports various conductor types, including flexible and rigid wires.
Technical specifications:
- Flexible wire: 0.08–2.5mm²
- Rigid wire: 0.2–4mm²
- Connection capacity: 0.08–4mm²
- Rated voltage: 450V AC
- Rated current: 32A
- Working temperature: -40℃ to 105℃
The wide conductor compatibility allows CMK425 to meet different electrical installation requirements.
Whether used in fixed wiring systems or equipment connections, CMK425 provides flexible application possibilities.
Recommended stripping length:
10mm / 0.39 inch
Proper stripping length helps ensure stable contact and reliable electrical performance.
