Product Overview
Westinghouse ARDCR contact cartridges restore reliable circuit switching to Type AR and Type ARD industrial control relays. Rated for 600V DC service, each cartridge functions as a reversible contact block that configures for normally open or normally closed operation depending on mounting orientation. Designed for demanding machine-tool logic panels, these replacement cartridges maintain proper contact pressure and arc clearance across heavy-duty industrial cycles.

Frequently Asked Questions
Which relay series use the ARDCR contact cartridge?
This cartridge fits Westinghouse and Cutler-Hammer Type AR and Type ARD industrial control relays. It carries manufacturer style number 624B094G07.
How is the contact cartridge configured for normally open or normally closed operation?
The cartridge is mechanically reversible. Installing it with the contact face in the upright position provides normally open operation, while inverting the cartridge sets it to normally closed operation.
Are the mounting screws included?
Yes. Two threaded mounting screws are included with each cartridge.
How does the ARDCR cartridge differ from standard AC Type AR cartridges?
The ARDCR is engineered specifically for 600V DC circuits in Type ARD relays, whereas standard AR cartridges are designed for AC duty. It features dedicated screw terminals and style number 624B094G07.
Before solid-state logic took over the cabinet, Westinghouse made relay cartridges you could flip upside down to change the circuit. Drop this into your ARD bank and keep a dependable piece of industrial iron running.
