CX2.5R Feed Through Spring Clamp Terminal Block is used for safe and reliable wire-to-wire electrical connections in industrial control panels, switchgear assemblies, machine wiring, automation systems, and electrical distribution applications. It provides a secure feed-through connection between incoming and outgoing conductors while ensuring compact panel wiring, vibration-resistant electrical continuity, and maintenance-free performance. The Red colour housing is especially useful for circuit identification, phase marking, and organized wiring in industrial electrical systems.
CX2.5R works as a 2.5 sq.mm feed-through spring clamp terminal block that creates electrical continuity between two conductor points. The spring clamp mechanism is operated using a screwdriver, allowing wire insertion into the clamp opening. Once the screwdriver is removed, the spring automatically applies constant pressure to the conductor, creating a gas-tight, vibration-proof, and maintenance-free electrical connection. This design eliminates loose connections and improves long-term reliability in industrial environments.
The Red colour body helps in phase identification, circuit marking, and structured panel wiring. It improves visual circuit recognition during installation and maintenance, reducing wiring mistakes and improving electrical safety. The spring clamp connection technology also ensures secure wire holding and reduces chances of loose electrical contacts in vibration-prone industrial environments.
CX2.5R is manufactured using high-grade Polyamide insulated housing that provides excellent electrical insulation, flame resistance, and strong mechanical durability. Its spring clamp mechanism provides torque-independent wire clamping, while the industrial-grade conductive components ensure low resistance current transfer and long service life in demanding industrial applications.
Using CX2.5R improves panel wiring by creating a compact and organized feed-through connection in control panels and electrical cabinets. Its 5 mm slim design saves DIN rail space, reduces wiring clutter, and makes installation faster. The Red colour coding also helps create visually organized panel layouts for easy maintenance and troubleshooting.
