2.5 mm2 3 LVL PUSH IN SPR CL INT SHRT TB – CPTL2.5(I.S)

Product Description

The CPTL2.5(I.S) is a 2.5 sq.mm plug-in test disconnect terminal block specially designed for industrial electrical systems where circuit testing, temporary signal isolation, structured conductor termination, and maintenance-friendly electrical wiring are required in one compact terminal block. This terminal block is widely used in PLC control panels, instrumentation systems, process automation panels, relay logic systems, signal monitoring circuits, and machine control wiring applications where engineers require safe access for circuit testing and electrical isolation without disturbing field wiring.

In industrial control systems, signal circuits often require routine testing, calibration, troubleshooting, fault diagnosis, and maintenance isolation. In normal terminal blocks, technicians may need to remove conductors manually to test or isolate a circuit, which increases maintenance time and can create wiring mistakes. The CPTL2.5(I.S) is designed to eliminate these problems by providing a dedicated plug-in disconnect and testing facility inside the terminal block body.

This allows technicians to isolate a signal circuit temporarily for testing, measurement, calibration, maintenance, or fault-finding without disconnecting field conductors.

The terminal block combines feed-through electrical continuity with test disconnect functionality, making it highly suitable for industrial electrical systems where signal monitoring and service-friendly panel wiring are important.

One of the biggest advantages of the CPTL2.5(I.S) is its plug-in isolation link design. Under normal operation, the terminal provides stable electrical continuity between incoming and outgoing conductors. During testing or maintenance, the disconnect plug can isolate the circuit safely without disturbing the conductor termination.

This improves:

✔ Faster maintenance work
✔ Safer signal isolation
✔ Easier circuit testing
✔ Reduced wiring disturbance
✔ Better troubleshooting efficiency

In industrial automation systems, this type of terminal block is widely used in:

• PLC signal circuits
• Process instrumentation loops
• Relay logic panels
• Machine control wiring
• Sensor monitoring circuits
• Signal isolation systems
• Testing panels
• Automation control systems
• Electrical maintenance systems
• Process control cabinets

The push-in spring clamp connection technology is another important feature of the CPTL2.5(I.S). Instead of conventional screw tightening, conductors can be inserted quickly using the push-in clamp system.

This provides:

✔ Faster installation
✔ Secure conductor retention
✔ Low contact resistance
✔ Vibration-resistant electrical continuity
✔ Long-term wiring reliability

This makes the terminal block suitable for industrial environments where electrical systems operate under vibration, heat, continuous electrical load, and maintenance-heavy applications.

Its feed-through with test disconnect structure helps combine normal signal transmission and testing functionality inside one compact terminal unit. Instead of installing separate disconnect accessories, test points, and feed terminals, engineers can use one modular terminal block to achieve multiple functions.

This improves:

✔ Space saving
✔ Better panel organization
✔ Reduced wiring complexity
✔ Faster maintenance access
✔ Professional panel finishing

The DIN rail mounting design makes installation simple and modular. The terminal block can be mounted quickly inside industrial electrical cabinets and arranged in structured terminal assemblies.

Its 2.5 sq.mm conductor capacity makes it suitable for industrial signal wiring, control circuits, instrumentation loops, and low-voltage automation systems.

The body is manufactured using industrial-grade flame retardant thermoplastic material, providing:

✔ High insulation strength
✔ Heat resistance
✔ Mechanical durability
✔ Corrosion resistance
✔ Safe industrial electrical protection

This insulated construction improves electrical safety during servicing and reduces accidental contact risks.

The plug-in disconnect mechanism allows easy insertion and removal during maintenance work, making it a preferred terminal block for engineers and electricians working in process automation, instrumentation, industrial controls, and maintenance-intensive electrical systems.

Because of its test disconnect functionality, push-in spring clamp technology, compact DIN rail construction, and industrial-grade durability, the CPTL2.5(I.S) is widely used in modern industrial electrical systems where safe testing and signal isolation are essential.

Its compact modular design, structured testing function, secure electrical continuity, and maintenance-friendly operation make it a professional terminal block solution for industrial signal control applications.
