Why Choose the TE Connectivity ZK2.5-4P-WH PI-Spring Terminal Block?
The TE Connectivity ZK2.5-4P-WH is a compact four-position PI-Spring feed-through terminal block designed for fast, reliable conductor connections and distribution in industrial control panels, machinery and automation equipment. Part of the TE Connectivity ENTRELEC SNK series, this white terminal combines spring-force connection technology with a space-efficient 5.2 mm DIN rail footprint.
Its four-position configuration allows four conductors to be connected within a single electrical circuit, providing a practical solution for branching and distribution without requiring additional terminal width. PI-Spring technology supports efficient conductor insertion while maintaining consistent spring pressure, helping deliver dependable electrical contact and reducing wiring effort during panel assembly.
The ZK2.5-4P-WH is rated at 24 A and 1000 V to IEC and accepts flexible conductors up to 2.5 mm² and rigid stranded conductors up to 4 mm² / 12 AWG. Its white UL 94 V-0 polyamide housing, IP20 protection and compatibility with standard TH35 DIN rails make it well suited to professional high-density industrial wiring.

Efficient Four-Conductor Distribution with PI-Spring Technology
PI-Spring terminal blocks use spring-force technology to maintain reliable conductor contact while supporting efficient panel wiring. The ZK2.5-4P-WH combines this connection method with four positions in one electrical circuit, allowing multiple conductors to be distributed or branched from a compact terminal without increasing the 5.2 mm DIN rail footprint.
The ENTRELEC SNK platform supports modular industrial panel construction, enabling compatible terminals and accessories to be arranged into organised assemblies. With its white housing, four-position configuration and broad conductor compatibility, the ZK2.5-4P-WH is particularly useful in automation and control systems where dense, clearly organised multi-conductor wiring is required.
Typical Applications
- Industrial control panels and electrical cabinets.
- PLC and distributed I/O wiring.
- Machine building and OEM automation systems.
- Multi-conductor distribution and branching circuits.
- Process control and instrumentation equipment.
- Power and signal distribution assemblies.
- High-density DIN rail terminal installations.
