The CX2.5/4O Feed Through Terminal Block is a compact and high-performance spring clamp electrical connection component designed for secure wire termination in industrial, commercial, and control panel applications. It is specially engineered to provide safe electrical continuity between connected conductors while improving cable organization and reducing wiring complexity inside electrical panels. This feed through terminal block is widely used in switchgear systems, automation panels, machine wiring systems, distribution boards, and industrial electrical installations where reliable electrical performance and maintenance-free wire connections are essential.
In modern electrical panel installations, secure wire termination and organized cable routing are essential for improving safety and simplifying maintenance. Traditional screw-type terminal blocks often require periodic tightening and may loosen in vibration-prone environments. The CX2.5/4O Feed Through Terminal Block solves this problem by using a spring clamp connection mechanism, which provides constant contact pressure and creates a secure, maintenance-free electrical connection. This makes it an ideal solution for industrial electrical systems where long-term reliability and stable conductor retention are critical.
One of the major advantages of the CX2.5/4O Terminal Block is its feed through connection design, which allows conductors to be connected safely from one side to the other through a secure conductive path. This helps create clean and organized wiring systems inside electrical panels while reducing unnecessary wire joints and cable clutter. It also improves electrical continuity and creates a more professional panel layout for electricians and panel builders working on industrial and commercial electrical installations.
The CX2.5/4O 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 design eliminates the need for periodic retightening and provides torque-independent, 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 mechanical vibration or continuous operation.
The body of the CX2.5/4O 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 mechanical stress and temperature variations.
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 CX2.5/4O 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 CX2.5/4O 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.
