Schneider Electric Square D 8501 Type K Relays

Schneider Electric Square D 8501 Type K (8501K) Relays offer 10A or 15A plug-in switching and are designed for multipole switching applications up to 240VAC. These relays feature industry-standard wiring and pin arrangements, making them suitable replacements for many similarly configured relays. Additionally, the socket-mounted construction enables technicians to replace a relay without changing the existing wiring or mounting hardware. The 8501K series is suitable for AC or DC operation and offers DPDT, 3PDT, and DPDT latching configurations. Options include horsepower-rated models, manual operators, a red pilot light, and an alternating variant (8501KA) with a toggle switch that lets an operator lock one side of a duplex system to prevent alternation. Schneider Electric Square D 8501 Type K Relays are ideal for material handling, lighting control, HVAC/R, and industrial applications.
