ST3PF, K, Y, R time relay is an imported Japanese Fuji Electric technology manufacturing, with small size, light weight, high delay accuracy, wide delay range, good reliability, long life and other characteristics, products in line with international standards, the most suitable for various high-precision, high-reliability automatic control field work delay control.
The ST3PF series time relays are compact, lightweight devices with high delay accuracy and a wide delay range, suitable for high‑precision, high‑reliability automatic control applications. The series includes four models—ST3PF (power‑off delay), ST3PK (disconnection delay), ST3PY (star‑triangle start delay) and ST3PR (reciprocating cycle delay).\n\nThe manual details the technical parameters, wiring diagrams, installation options (screw‑type, rail‑mounted, or panel mounting), and important usage notes such as correct polarity for DC power, minimum timing requirements, and safety precautions. This manual is written in Chinese.

Frequently asked questions
Within what voltage range should the control power be applied?
The control power should be used within 85 % to 110 % of the rated control voltage.
How should the relay be mounted on a standard 35 mm DIN rail?
Use a TP28X type rail‑mounted socket, which is suitable for a 35 mm standard rail.
