he CP2.5/4R is a high-performance DIN rail push-in terminal block designed for industrial electrical wiring and control panel applications. This terminal block is widely used in automation systems, electrical distribution panels, machinery wiring, PLC systems, and industrial control cabinets. The product belongs to the CP series of push-in terminal blocks and is known for its compact design, reliable electrical connection, and easy installation.
The CP2.5/4R terminal block is engineered to provide secure and maintenance-free connections for electrical conductors. Its push-in spring connection technology allows fast wire insertion without requiring special tools, reducing installation time and improving wiring efficiency. The “4R” designation generally refers to a 4-wire feed-through configuration with a red-colored housing for easy circuit identification.
This terminal block is manufactured using high-quality polyamide insulation material that offers excellent thermal resistance, mechanical strength, and flame-retardant properties. It is suitable for demanding industrial environments where safety, durability, and reliable electrical performance are critical.
Industrial electricians and panel builders prefer the CP2.5/4R because it simplifies wiring tasks while maintaining strong electrical conductivity and vibration resistance. The product is commonly installed on standard DIN rails and supports a wide range of conductor sizes, making it highly versatile for industrial electrical systems.
The CP2.5/4R terminal block uses advanced push-in spring clamp technology for rapid and secure wire connections. This feature minimizes installation time and improves productivity in industrial wiring applications.
Its compact structure allows efficient use of panel space, making it ideal for high-density control panels and electrical cabinets.
The terminal block provides stable current transmission and low contact resistance, ensuring safe and efficient electrical operation.
Manufactured from durable Polyamide PA66 material, the product offers excellent resistance to heat, chemicals, and mechanical stress.
The red-colored housing helps technicians identify circuits quickly during installation, troubleshooting, and maintenance.
The spring clamp system ensures secure conductor retention even in high-vibration industrial environments.
Unlike screw-type terminal blocks, push-in terminals reduce the risk of loose connections caused by vibration or thermal expansion.
