This listing is for a lot of three (3) new Tennant part number 2660 relays, each marked "P/N 2660 / 2713 / USA / 36 VOLT" as clearly visible in the photos. These are OEM-style 36-volt coil relays designed for use in Tennant industrial floor care equipment, consistent with the electrical architecture of battery-powered sweepers and scrubbers operating on a 36V DC system. Each relay features a compact square-body black molded housing with five blade-style terminals — two coil pins and three load/switching pins — visible in the underside photos, indicating a standard SPDT (Form C) or similar multi-contact configuration used for motor control or contactor switching circuits. Made in the USA per the body marking, these new-condition units are direct service replacements for Tennant equipment requiring P/N 2660 relays, with the secondary code "2713" likely indicating a date or manufacturing lot code rather than a separate part number.
