Schneider Electric 8501NR51 Relay Socket Type K

Schneider Electric 8501NR51 Relay Socket is an eight-pin tubular, single-tier plug‑in socket designed to accept Square D 8501K Type K relays and 9050JCK timers. It supports DIN rail or panel mounting and uses a single row of screw‑clamp terminals for wiring, with eight tubular contacts that align with the relay’s pins for reliable operation in industrial control panels. The socket is specified for use with the 8501K family (Type K) relays, enabling quick plug‑in replacement in manufacturing, conveyance, and other industrial environments. Its compact, single‑tier construction simplifies integration into control enclosures and minimizes wiring complexity while providing a robust interface between the relay and the control circuit. Electrical rating commonly associated with this family is up to 600 VAC at 10 A, aligning the socket with standard control relays used in medium‑voltage applications. In everyday installations, you’ll pair the 8501NR51 with compatible 8501K relays to achieve dependable relay control in automation tasks, machine control, and other panel‑mounted switching applications.
