Square D RS14 8501 Miniature Relay Class 8501

Square D 8501RS14 miniature plug‑in relay, a member of the Class 8501R family, provides four Form‑C contacts (4C/O) in a compact plug‑in package designed for control logic and power switching in industrial equipment. The RS14 variants are available with coil options such as 24 VAC (and related 24 VDC configurations), pairing a four‑pole, 4PDT contact set with a pilot light option and a convenient test button on select models. Rated operational current and switching capabilities vary by variant, with common RS14 configurations listed around 5 A at 250 VAC for resistive loads and up to higher ratings on other 8501RS14 options; users should match the exact variant to their load and supply. The relay is UL listed with Square D relay sockets and CSA certified, and insulation ratings align with Ui up to 250 V (IEC) / 300 V (UL/CSA); it supports maximum switching voltages up to 250 VAC / 28 VDC (IEC) or 300 VAC / 30 VDC (UL). Operating temperature ranges from -40 to +85 °C, enabling use in harsh environments, and the units deliver substantial durability with mechanical life up to 10 million cycles and electrical durability around 100,000 cycles under resistive loads. These features make the 8501RS14 well suited to control circuits in material handling, processing, HVAC/R, and other automation applications where a compact, reliable four‑pole relay is required, and where precise coil variants and contact ratings align with the specific control task at hand.
