Alternating Plug-In Relay From Schneider Electric Controls Pump Loads

Palatine, IL - The Schneider Electric Relay Competency Center (SE Relays LLC) announces the release of the Square D® brand 8501KA series alternating relay. This feature-rich product offers a direct replacement for competitive alternating plug-in relays that are utilized in the pump industry to control multiple loads.

"The 8501KA alternating relay was developed to provide a superior and cost-competitive alternative to existing alternating plug-in relays," said Dipin Jain, marketing product manager, Relay Competency Center. "The relay offers 12-amp contact ratings while utilizing less space on the DIN rail. The product also works well as a drop-in replacement in the MRO industry and offers features that appeal to OEM panel builders."

While the 8501KA alternating relay specifically is designed for the pumping industry, its unique design is suitable for any application that requires a device to provide switching capabilities to control multiple loads. Customers can reduce bearing and pump wear caused by long runtimes by utilizing the relay's ability to toggle the load between multiple devices.

Several contact and voltage configurations are available with the 8501KA alternating relays. The socket-compatible products have a top-mounted toggle switch to select the alternating mode applicable to the system. When used with the mating Square D brand socket, the relays have UL Listed approval status. This status streamlines agency approval when incorporating the product into a new design or replacing a competitive product in an existing system.

Common applications for the 8501KA alternating relays include irrigation systems and water treatment (pumping stations), compressors and HVAC fans. Like all 8501K relays, the KA series conforms to numerous international standards and meets the requirements of the European RoHS (Restriction of Hazardous Substances) directive.
