FAQs
What is the primary advantage of the push-in connection technology?
The push-in connection technology allows for fast, tool-free wire insertion, significantly reducing installation time and effort compared to traditional screw terminals.
What types of wires can be used with this terminal block?
It accommodates solid and flexible wires with a cross-section ranging from 0.14mm² to 4mm². A rated cross-section of 2.5mm² is specified.
What is the maximum voltage and current this terminal block can handle?
The terminal block has a nominal voltage rating of 800V and a nominal current capacity of 20A.
What mounting rails are compatible with the PT 2.5-PE/3L?
It is compatible with standard NS 35/7.5 and NS 35/15 DIN mounting rails (top hat rails).
How do I disconnect a wire from the push-in terminal?
You can disconnect a wire by using a suitable screwdriver or probe to activate the release mechanism located at the terminal entry point.
What does the 'PE' in PT 2.5-PE/3L signify?
PE stands for Protective Earth, indicating that this terminal block includes a connection point for grounding purposes, essential for safety.
Is this terminal block suitable for outdoor use?
This terminal block is designed for industrial indoor applications. It is not rated for direct outdoor exposure without appropriate enclosure and protection against environmental factors.
Troubleshooting
Wire will not insert into the terminal block.
Ensure the wire is properly stripped to the correct length and the conductor is solid and not frayed. Check that no foreign material is obstructing the terminal entry.
Connection feels loose or intermittent.
Verify the wire has been fully inserted. Ensure the correct wire cross-section is being used within the specified range. Check the mounting rail for proper seating of the terminal block.
Terminal block not securely attached to the DIN rail.
Confirm you are using the correct type of NS 35 mounting rail (NS 35/7.5 or NS 35/15). Ensure the terminal block's mounting clip is fully engaged with the rail.
High temperature at terminal connection.
Check if the connected wire's cross-section exceeds the maximum rating (4mm²). Ensure the current load does not exceed the nominal 20A capacity. Verify that all connections are firm.

Setup, Compatibility & Care
Setup:
- Mounting: Snap the terminal block securely onto a compatible NS 35/7.5 or NS 35/15 DIN mounting rail.
- Wire Preparation: Strip the wire end to the appropriate length (refer to marking on the block or documentation).
- Connection: Insert the prepared wire end directly into the push-in terminal until it is firmly seated. For disconnections, use a suitable screwdriver or probe to activate the release mechanism.
Compatibility:
- Mounting Rails: Exclusively compatible with NS 35/7.5 and NS 35/15 type DIN mounting rails.
- Wire Types: Suitable for solid and stranded wires within the specified cross-section range (0.14mm² - 4mm²).
Care:
- Cleaning: Clean the terminal block with a dry or slightly damp cloth. Avoid using solvents or abrasive cleaners, which can damage the material.
- Inspection: Periodically inspect connections for any signs of damage or loose wires, especially in high-vibration environments.
