Why Choose the TE Connectivity ENTRELEC ZK2.5-OR PI-Spring Terminal Block?

The TE Connectivity ENTRELEC 1SNK705030R0000 ZK2.5-OR is a compact orange PI-Spring feed-through terminal block designed for reliable conductor connections in industrial control panels, machinery and electrical distribution systems. Part of the ENTRELEC SNK series, it combines push-in and spring connection technology to provide fast installation while maintaining dependable electrical performance.

The ZK2.5-OR uses PI-Spring connection technology, allowing suitable solid conductors and stranded conductors fitted with ferrules to be inserted directly, while a screwdriver-operated spring mode accommodates other conductor types and simplifies disconnection. This versatile connection system helps reduce wiring time and conductor preparation during control panel assembly.

With an IEC rated current of 24 A, an IEC rated voltage of 1000 V and a compact 5.2 mm spacing, the ZK2.5-OR provides high electrical performance while minimising DIN rail space. Its distinctive orange housing also enables circuits or functions to be visually differentiated within complex terminal assemblies.

Fast and Reliable PI-Spring Terminal Connections

PI-Spring terminal technology combines the advantages of direct push-in wiring with conventional spring connection methods. Suitable prepared conductors can be inserted directly into the terminal, reducing installation time, while the spring mechanism can be operated using a screwdriver for connecting or releasing other conductor types.

The ZK2.5-OR combines this connection technology with the compact architecture of the ENTRELEC SNK series. Its 5.2 mm spacing helps panel builders achieve high wiring density, while the orange housing provides an effective way to distinguish particular circuits, voltages or functions from neighbouring terminal blocks.
