Square D Relay Master Contact Cartridge 8501XC4 600 VAC

The Square D 8501XC4 is a master contact cartridge designed for use with Class 8501 Type X NEMA control relays. Rated for 20 amperes at 600 VAC, this plug in cartridge allows the relay base to be configured with either a normally open or normally closed contact by flipping the cartridge orientation within the contact cavity. The blue color coding identifies the cartridge as a master type, which provides the primary contact function within the 8501X modular relay assembly. Compatible with the 8501XMO master control relay platform, the cartridge installs without disturbing field wiring, supporting field conversion between NO and NC contact states. The Class 8501 Type X relay family is widely used in machine tool, automation, and industrial control applications where modular construction, heavy duty cycle life, and ease of field maintenance are required.
