Why Choose the TE Connectivity ZK6-3P-BL 1SNK708021R0000 PI-Spring Terminal Block?
The TE Connectivity ZK6-3P-BL 1SNK708021R0000 is a robust three-position PI-Spring feed-through terminal block designed for reliable power and signal connections in industrial control panels, electrical enclosures and automation systems. As part of the TE Connectivity ENTRELEC SNK series, it combines fast spring-clamp conductor termination with a compact DIN rail format and an additional connection position for efficient conductor distribution.
The ZK6-3P-BL uses PI-Spring connection technology to provide fast and secure conductor termination without conventional screw connections. Suitable conductors can be inserted efficiently while the spring mechanism maintains dependable contact pressure. Its three-position, single-level configuration enables multiple conductors to be connected within one circuit, making it particularly useful for branching and distribution applications.
With an IEC current rating of 41 A and an IEC voltage rating of 1000 V, the ZK6-3P-BL is suitable for demanding industrial circuits. It accepts flexible conductors from 0.5–6 mm² and rigid stranded conductors up to 10 mm², while its blue polyamide housing and 8 mm terminal spacing provide clear identification and efficient DIN rail installation.

Three-Position PI-Spring Connections for Efficient Distribution
PI-Spring technology provides a fast and dependable method of terminating electrical conductors in industrial control equipment. Suitable conductors can be connected efficiently while the spring mechanism maintains consistent contact pressure, helping simplify panel assembly and reduce maintenance compared with conventional screw-clamp connections.
The ZK6-3P-BL combines this connection technology with a three-position design that allows conductors to be branched or distributed within a single circuit. Its 8 mm pitch, broad conductor capacity and DIN rail mounting format make it an efficient choice for industrial installations where higher-current connections, compact wiring and clear blue terminal identification are required.
Typical Applications
- Industrial control panels and electrical cabinets.
- Power and signal distribution circuits.
- Three-conductor branching and distribution.
- Machine building and OEM automation systems.
- PLC and industrial control wiring.
- DIN rail installations requiring blue circuit identification.
