Schneider Electric 8501X Square D® NEMA Control Relays combine heavy-duty construction with a modular design for demanding control applications. These panel-mounted devices include control, master, timing, latching, and utility relay configurations. The replaceable, convertible contact cartridges streamline maintenance and allow contact arrangements to be modified without replacing the complete relay. Additional features include color-coded, plug-in contact cartridges and a common mechanical tie between the contacts. The basic variants accommodate up to four contact cartridges, while modular adder decks offer expanded configurations. Timing or latching attachments can also be added to compatible basic relays, reducing the number of individual components needed for multiple control functions. Schneider Electric 8501X Square D NEMA Control Relays feature a 600VAC maximum voltage rating and a temperature range of -40°C to +71°C.
