Product newsWhat Makes the PRK Range Special?
Here’s a breakdown of the key benefits:
Tool-Free Wiring: Thanks to the push-in connection system, you don’t need any tools to connect wires. Just push the wire in—done!
Secure Connections: The internal spring mechanism holds wires tightly and safely, reducing the risk of loose connections.
Quick Potential Distribution: The PQI cross-connection system lets you easily bridge terminals to distribute voltage across multiple points.
Durable and Safe Materials: Made from high-quality polyamide (PA 6.6-V 0), the housing is resistant to heat (up to 120°C), chemicals, and electrical creep.
Flexible Labelling: Each terminal offers three marking options, making it easy to keep your wiring organised.
What’s in the PRK Range?
The PRK series includes:
- Feed-through and PE terminals: Available in 6 wire sizes (1.5 mm² to 16 mm²) with 2, 3, or 4 connection points.
- Double-level terminals: Save space with stacked terminals for 1.5 mm² to 4 mm² wires.
- Three-level initiator terminals: Ideal for sensor and actuator wiring.
- Motor connection terminals: Designed for 2.5 mm² motor wiring.
- Transformer terminals: With fuse options for 4 mm² wires.
- Accessories: DIN rails, end stops, marking systems, and more.

Why Choose PRK?
If you're looking for a terminal block that’s easy to use, reliable, and versatile, the PRK range is a smart choice. It’s built for speed and safety, with features that make installation and maintenance a breeze.
The low insertion resistance of the PRK push-in technology makes it easy to insert rigid and flexible conductors with ferrules. The rated cross-section refers to flexible conductors with ferrules, meaning that solid conductors with the next highest cross-section can also be contacted.
