Connection Technologies Available: Screw Clamp, Spring Clamp & Push-In
When it comes to DIN rail terminal blocks, the choice of connection technology is crucial for reliability and ease of use. Here are the main types we offer:
Screw Clamp Connection
This traditional method uses a screw to securely fasten the wire. It’s widely trusted for solid contact and great for applications where vibration isn’t a big concern. Our screw connection terminal options include durable brass wire connector blocks to ensure steady electrical control panel wiring and long-term stability.
Spring Clamp / Cage Clamp
Spring cage terminals offer a vibration-resistant, maintenance-free connection. Instead of screws, they use a spring mechanism to hold wires firmly. This technology simplifies assembly with quicker wire insertion and release, perfect for fast installation on 35mm top-hat rails and modular terminal block setups.
Push-In Technology
Push-in wire connectors allow wires to be directly plugged in without any tools, speeding up wiring significantly. These are ideal for feed-through terminal blocks where ease and speed matter most. They maintain excellent contact and pull-out strength, offering a modern approach to the DIN rail mount connector.
Each technology suits different setups from multi-level terminal blocks to potential distributor blocks, ensuring you get the right fit for your electrical cabinet components.

Essential Accessories for Cabinet Assembly
When setting up your electrical cabinet with DIN rail terminal blocks, having the right accessories is crucial for a tidy, safe, and efficient installation.
- End Brackets / End Stops These keep your terminal strips firmly in place on the 35mm top-hat rail, preventing any movement caused by vibration or handling. They ensure the stability of the entire terminal block assembly during operation.
- Jumper Bars / Cross Connectors Easily link multiple points within a terminal strip using jumper bars. This is especially useful for potential distributor blocks or multi-level terminal blocks, allowing quick distribution of power or signals without extra wiring. Check out our range of jumper bars designed to fit screw connection terminals perfectly.
- End Covers & Partition Plates For added safety and neatness, end covers protect the terminal block ends, preventing accidental contact. Partition plates separate different circuits within the terminal strip, reducing electrical noise and improving isolation in complex electrical control panel wiring.
- Marking Strips & Labeling Clear identification is vital. Marking strips and labeling solutions help label each terminal or wire clearly, which simplifies troubleshooting and maintenance down the line. Use marking systems compatible with your terminal block series to keep everything organized.
Together, these accessories complement modular terminal blocks, whether you’re utilizing screw clamp, spring cage, or push-in wire connection technologies. They help maintain a professional, reliable electrical cabinet assembly every time.

Installation & Wiring Guidelines for Din Rail Terminal Block
Getting your DIN rail terminal block installed properly is key to ensuring reliable electrical control panel wiring. Here’s a simple step-by-step guide to help you:
Step-by-step Installation
- Mount the DIN rail: Secure your 35mm top-hat rail firmly inside the electrical cabinet or control panel.
- Snap on the terminal blocks: Slide each modular terminal block onto the DIN rail. Ensure they click into place without gaps.
- Arrange accessories: Add end brackets, jumper bars, or marking strips where needed to organize and maintain the terminal strip assembly.
- Connect wiring: Insert stripped wires into the appropriate terminal points based on your circuit design.
Wire Stripping Length
- Strip the wire insulation to the manufacturer’s recommended length, typically around 8-12 mm for screw clamp and spring cage terminal blocks.
- Avoid over-stripping to prevent exposed wire beyond the connector, which can cause short circuits.
- For push-in wire connectors, confirm the wire is stripped cleanly without any nick or damage to ensure a solid connection.
Proper Torque Application
- Use a calibrated screwdriver or torque driver to tighten screw connections to the specified torque value.
- Over-tightening can damage the brass wire connector block or terminal strip, while under-tightening might cause poor contact or overheating.
- Refer to the manufacturer’s torque specs, generally between 0.5 to 0.6 Nm for screw clamp terminals.
- For spring cage or push-in types, verify locking mechanisms firmly hold the wire without excessive force.
By following these simple installation and wiring guidelines, you ensure that your screw connection terminal or spring cage terminal block functions safely and efficiently in your electrical cabinet components.
