Cutler-Hammer 8779C02G03

In May of 1993, the test port changed on DS circuit breakers that have Digitrip RMS trip units. The test port was moved from the front cover to the left-hand side, as you face the front of the breaker. The port was also changed from an 11-pin banana plug to a 9-pin plug. The adapter is for using a 140D481(G02R), (G02RR) or (G03) tester to test DS breakers with Digitrip that have the side-mounted, 9-pin plug. The adapter converts the banana plugs on the tester to a 9-pin plug. DO NOT use the adapter with the old 140D481G01 or 140D481G02 tester. 

On Magnum breakers, the test port is located on the front cover of the trip unit. The port is a 14-pin plug; the adapter converts the banana plugs on the tester to a 14-pin plug.

Note: ¹ These parts are used with any breaker that was upgraded with “Digitrip Retrofit Kits.”
