Eaton ARA20 – Frequently Asked Questions
1) Will the Eaton ARA20 top deck adder fit on a relay other than an AR/ARD machine tool relay?
No. The ARA20 is built for the Eaton AR/ARD Series machine tool relay platform only. It mounts on top of the basic AR/ARD relay with three screws. If your panel uses a different relay family, this adder will not mount to it.
2) Do I have to rewire the relay to add the Eaton ARA20 four-pole deck?
No rewiring of the existing relay is needed. The ARA20 seats on top of the basic AR/ARD relay with three screws and does not interfere with wiring already landed, testing points, or convertible cartridges already installed. You wire only the new poles it adds.
3) How many contacts does the Eaton ARA20 top deck adder actually give me?
The ARA20 is a four-pole top deck with a 2 NO contact configuration, plus 2 blank cavities. So you get two normally open switching points wired out of the box, with two empty positions left on the deck for further configuration.
4) How much room do I need above the relay in the enclosure for an ARA20 deck adder?
The ARA20 measures 2.88 in wide, 2.75 in deep and 4.94 in high, sized to the base relay footprint. Because it stacks on top of the relay, check vertical clearance from the relay mounting surface to the wireway or door before ordering.
5) Should I add a top deck adder or replace the relay to get more poles?
If the existing AR/ARD relay coil and base are sound and you only need more contacts, the ARA20 deck adder is the shorter job: three screws on top of the relay in place, existing wiring and convertible cartridges undisturbed, and four more poles with 2 NO available. Swapping the whole relay means pulling every landed conductor. Replace the relay instead when you need a different coil voltage or the relay itself is failing.
6) What part number do I order for the Eaton four-pole 2NO top deck adder?
Order Eaton ARA20. That is the single model for the AR/ARD four-pole top deck adder in the 2 NO configuration.
