Overview

The TE Connectivity ZK2.5-4P PI-Spring terminal block (SKU 1SNK705012R0000) is a compact, 4-pole feed-through terminal block designed for efficient conductor distribution and branching in industrial control panels, automation systems, and power distribution applications. With a rated cross-section of 2.5 mm² and a spacing of 5.2 mm, this terminal block supports flexible wiring configurations while maintaining high current capacity. The PI-Spring clamp connection type accommodates a wide range of conductor sizes, including flexible (0.22–2.5 mm²), rigid (0.2–4 mm²), and options with or without insulated ferrules, ensuring compatibility with diverse wiring requirements. Rated for 24 A at 1000 V, the ZK2.5-4P meets stringent electrical performance standards, including a short-time withstand current of 300 A for 1 second and a dielectric test voltage of 2200 V. Its compact 5.2 mm width and 80.2 mm height allow for dense packing in control cabinets, while the grey polyamide insulation material ensures durability and resistance to environmental stress. Designed for DIN-rail mounting on TH35-7.5 or TH35-15 rails per IEC 60715, the terminal block features a wire stripping length of 11.0 mm for consistent terminations. The product operates reliably across a wide temperature range (-55°C to +110°C) and is optimized for applications requiring secure, maintenance-free connections in automation, process control, and power management systems. With a pollution degree rating of 3 and IP20 protection for main terminals, the ZK2.5-4P is engineered for long-term performance in demanding industrial environments.
