TE Connectivity ZK2.5-4P-OR 1SNK705032R0000 is an orange ENTRELEC SNK four-position PI-Spring feed-through terminal block with 5.2 mm spacing, conductor capacity up to 4 mm² and IEC ratings of 24 A and 1000 V for compact industrial DIN rail wiring.
Why Choose the TE Connectivity ZK2.5-4P-OR PI-Spring Terminal Block?
The TE Connectivity ZK2.5-4P-OR is a compact four-position PI-Spring feed-through terminal block designed for fast, reliable conductor connections in industrial control panels, machinery and automation equipment. Part of the TE Connectivity ENTRELEC SNK series, this orange terminal combines push-in spring connection technology with a space-efficient 5.2 mm DIN rail footprint.
Its four-position configuration allows multiple conductors to be connected within a single feed-through circuit, making the ZK2.5-4P-OR particularly useful for distributing or branching connections without increasing terminal width. PI-Spring technology provides consistent spring pressure on the conductor and enables efficient wiring compared with conventional screw-operated terminals.
The terminal 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 orange polyamide housing provides clear circuit identification, while compatibility with standard TH35 DIN rails supports straightforward installation in professional control-panel assemblies.
Key Advantages
Four-position design enables convenient conductor distribution or branching within one circuit.
PI-Spring connection technology provides fast, secure and consistent conductor termination.
Compact 5.2 mm terminal spacing maximises wiring density on the DIN rail.

Fast Multi-Conductor Connections with PI-Spring Technology
PI-Spring terminal blocks use spring-force connection technology to maintain reliable conductor contact without relying on screw tightening. The ZK2.5-4P-OR combines this connection method with four positions in a single circuit, providing an efficient way to distribute or branch conductors while retaining a narrow 5.2 mm terminal footprint.
The ENTRELEC SNK platform is designed for modular industrial panel construction, enabling compatible terminals and accessories to be combined into organised DIN rail assemblies. The ZK2.5-4P-OR's orange housing further assists circuit identification, making it particularly useful in automation and control applications where dense, clearly organised 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.
