Schneider Electric 8501XC1 Contact Cartridge Relay

Schneider Electric's Square D 8501XC1 is a standard contact cartridge for Harmony 8501X NEMA control relays. It provides a single 1 NO or 1 NC contact in a black housing, designed for plug-in installation into compatible 8501X bases. Rated for up to 600 VAC and up to 10 A resistive loads, it uses a 24 V DC coil. This cartridge enables quick configuration or replacement of the switching element in multi-pole assemblies, allowing easy tailoring of control circuits without replacing the entire relay. As part of the 8501 family, the 8501XC1 supports modular, field-replaceable contacts for common industrial control applications where a single-form contact is sufficient and switching up to 600 VAC is required.
