## Summary description

Phoenix Contact double-level terminal block, model PTTB 2,5-LA 24 RD, part number 3211456. Designed for secure and reliable wire connections in electrical panels and industrial automation systems. This grey 4-conductor terminal block provides efficient space-saving distribution and signal routing.

## Long description

The Phoenix Contact PTTB 2,5-LA 24 RD Double-Level Terminal Block Grey 4-conductor is a reliable electrical component designed for efficient wire connections in industrial automation systems and electrical control panels. This grey double-level terminal block offers space-saving distribution and signal routing, featuring a compact design with a width of 5.2 mm and a length of 68 mm. It accommodates a cross section from 0.14 mm² to 4 mm² and supports an AWG range of 26 to 12. Operating with a nominal voltage of 500 V and a nominal current of 20 A, it provides secure installation on standard NS 35/7,5 and NS 35/15 mounting rails.
Advantages
This terminal block utilizes an efficient Push-in connection method that allows for easy and tool-free wiring of solid conductors or conductors equipped with ferrules. Its compact double-level configuration maximizes panel space efficiency while maintaining high performance. The front connection layout enables convenient wiring even in highly confined spaces. Additionally, the unit is equipped with testing facilities in the double function shaft along with an extra test connection to simplify diagnostic and maintenance procedures.
Suitable for
Electrical control panels and distribution boards
Industrial automation and control systems
Signal routing and power distribution in restricted spaces
This terminal block may not be suitable for applications requiring wire cross-sections outside the specified range of 0.14 mm² to 4 mm² or operating voltages significantly exceeding 500 V. It is specifically designed for standard industrial mounting rails and cannot be directly mounted on non-standard surfaces without appropriate adapters.
Key specifications
Nominal voltage: 500 V
Nominal current: 20 A
Connection method: Push-in connection
Conductor cross section: 0.14 mm² to 4 mm²
AWG range: 26 to 12
Width: 5.2 mm
Length: 68 mm
Color: Gray
Mounting type: NS 35/7,5 and NS 35/15 rails
How to use
To install the terminal block, securely snap it onto a compatible NS 35/7,5 or NS 35/15 mounting rail inside the electrical panel. Prepare the wire by stripping it to the appropriate length or attaching a ferrule for solid or stranded conductors. Insert the prepared conductor directly into the Push-in connection opening until it is fully seated and securely locked in place. Use the integrated test connections in the function shaft for routine electrical testing and diagnostics without disconnecting the wiring.
What to consider before purchase
Verify that the wire cross-section falls within the 0.14 mm² to 4 mm² range
Ensure the available panel space matches the 5.2 mm width and double-level layout
Check that the mounting rail type is compatible with NS 35/7,5 or NS 35/15
Confirm that the electrical parameters of 500 V and 20 A meet system requirements
Usage recommendations: Always isolate power to the electrical panel before installing, wiring, or performing maintenance on the terminal block. Ensure that all conductors are correctly prepared and fully inserted into the Push-in terminals to maintain a secure and reliable electrical connection.
