TE Connectivity ZK2.5-3P 1SNK705011R0000 is a grey 2.5 mm² ENTRELEC SNK three-position PI-Spring feed-through terminal block rated at 24 A and 1000 V IEC for compact conductor distribution and branching on DIN rail.

The TE Connectivity ZK2.5-3P 1SNK705011R0000 is a compact 2.5 mm² three-position PI-Spring feed-through terminal block from the ENTRELEC SNK series. Designed for industrial control panels, machinery and automation systems, it combines fast spring connection technology with three conductor connection points for convenient distribution or branching within a single terminal.
Unlike the standard two-position ZK2.5, the ZK2.5-3P provides three connection positions on one common circuit, allowing three conductors to be electrically connected together. This makes it particularly useful where a potential or signal needs to be distributed or branched without adding a separate jumper or additional terminal block.
The ZK2.5-3P has a compact 5.2 mm spacing while delivering IEC ratings of 24 A and 1000 V. It accepts flexible conductors from 0.22–2.5 mm² and rigid stranded conductors from 0.2–4 mm², providing a versatile, space-efficient solution for professional DIN rail wiring.
The defining feature of the ZK2.5-3P is its three-position, single-circuit configuration. All three conductor connection points belong to the same electrical circuit, allowing an incoming conductor to be distributed to two outgoing conductors, or enabling three conductors to be joined at a single DIN rail terminal. This can simplify control-panel wiring and reduce the need for additional distribution terminals or external jumpers.
TE Connectivity's PI-Spring technology combines two connection approaches in one terminal. Suitable prepared conductors can be inserted directly using push-in operation, while the spring can be opened with a screwdriver when connecting or removing other conductor types. Together with the narrow 5.2 mm profile, this makes the ZK2.5-3P particularly useful for densely populated industrial control cabinets where installation speed and space efficiency are important.

The ZK2.5-3P is a 2.5 mm² three-position PI-Spring feed-through terminal block from the ENTRELEC SNK series, designed to connect, distribute or branch three conductors within one common circuit.
The 3P designation indicates three connection positions. The terminal has one circuit and one level, allowing three conductors to be electrically connected together through the same terminal.
The ZK2.5-3P uses TE Connectivity PI-Spring technology, a spring terminal system that supports rapid conductor connection and secure spring-loaded retention.
The terminal accepts flexible conductors from 0.22–2.5 mm² and rigid stranded conductors from 0.2–4 mm². It also accepts insulated and non-insulated ferrules from 0.22–2.5 mm².
The ZK2.5-3P is rated at 24 A and 1000 V to IEC specifications. UL and CSA current ratings are 20 A, with a maximum UL/CSA main-circuit operating voltage of 600 V.
The ZK2.5-3P has a compact product spacing of just 5.2 mm, allowing three conductor connections to be provided within a narrow DIN rail footprint.
The ZK2.5-3P is designed for DIN rail mounting and is compatible with TH35-7.5 and TH35-15 rails.
The manufacturer catalogue specifies a standard package quantity of 50 pieces for the grey ZK2.5-3P 1SNK705011R0000.
TE Connectivity ENTRELEC SNK PI-Spring terminal blocks combine compact dimensions, efficient spring connection technology and flexible distribution options, helping panel builders, automation engineers and machine manufacturers create organised, space-efficient and maintainable industrial wiring systems.
