Product Description

The CX2.5/4Y Feed Through Spring Clamp Terminal Block is a compact and high-performance electrical connection component designed for secure wire termination in industrial, commercial, and control panel applications where safe electrical continuity and reliable conductor connection are essential. It is specially engineered to provide stable electrical connectivity between incoming and outgoing conductors while improving wiring organization and reducing installation complexity inside electrical panels. This feed through spring clamp terminal block is widely used in switchgear systems, automation panels, machine wiring systems, control cabinets, and electrical distribution boards where maintenance-free and vibration-resistant wire connections are required.

In modern electrical installations, wire termination reliability plays a major role in improving panel safety and reducing maintenance requirements. Traditional screw clamp terminal blocks may require periodic retightening and can loosen in vibration-prone environments. The CX2.5/4Y Feed Through Terminal Block solves this issue by using a spring clamp connection mechanism, which automatically applies continuous pressure on the conductor. This creates a secure electrical connection without the need for manual retightening, making it an ideal solution for industrial environments where long-term stability and maintenance-free operation are important.

One of the major advantages of the CX2.5/4Y Terminal Block is its feed through connection design, which allows conductors to be safely connected from one side to the other through a secure conductive current bar. This creates clean and organized wiring layouts inside electrical panels while reducing unnecessary wire joints and cable clutter. It also improves electrical continuity and makes panel wiring easier to maintain for electricians and panel builders working on industrial and commercial electrical installations.

The CX2.5/4Y is designed for 2.5 sq.mm conductor capacity and supports a rated current of 24A with a rated voltage of 1000V, making it suitable for low and medium power control circuits, signal wiring systems, machine control applications, and industrial electrical panels. Its dependable electrical performance ensures safe current flow and stable conductor termination in demanding industrial applications where secure and reliable wire connection is important.

A key feature of this terminal block is its spring clamp technology, which creates a secure electrical connection by applying continuous spring pressure on the conductor. This torque-independent design eliminates the need for periodic retightening and provides a vibration-resistant wire termination. It also reduces the chances of loose wiring, overheating, voltage drop, or electrical faults during long-term use. This makes the terminal block especially suitable for industrial applications exposed to vibration, mechanical stress, or continuous operation.

The body of the CX2.5/4Y Feed Through Terminal Block is manufactured using high-quality polyamide insulated housing, which offers excellent electrical insulation, heat resistance, impact strength, and long service life. This durable insulated housing protects internal conductive parts from accidental contact and improves overall electrical safety during operation. Polyamide construction also ensures reliable performance in industrial environments exposed to temperature changes and mechanical stress.

Its top-entry wire connection orientation allows convenient cable insertion and organized conductor routing inside electrical panels. This feature improves wiring convenience and reduces installation complexity, especially in compact electrical enclosures. The spring clamp mechanism is operated using a screwdriver, allowing quick wire insertion and secure conductor locking without complicated installation steps. This helps electricians reduce installation time and improve wiring accuracy in professional panel building applications.

The CX2.5/4Y is designed for DIN rail mounting and supports DIN 35 / DIN 35-15 rail systems, making installation fast, simple, and compatible with standard industrial panel structures. DIN rail mounting improves component organization, reduces installation time, and allows easy replacement or maintenance when required. This mounting flexibility makes the terminal block suitable for professional electrical panel building applications where efficient installation is essential.

Electrical safety is an important requirement in industrial wiring systems, and the CX2.5/4Y is designed with a rated surge voltage of 8KV and pollution degree 3, making it suitable for electrical environments exposed to voltage disturbances, dust, or contaminants. These safety features improve electrical reliability and support safe long-term operation in industrial applications.
