The Cutler Hammer 140D481G03 DS Breaker Test Kit is used to test and verify the pickup levels and time delay settings of a breaker’s Trip Unit. The original Test Kits were developed to test the Amptector Trip Units of the DS Breaker.
The Test Kit Adapter (Style # 8779C02G04) for the Magnum DS Digitrip Trip Units, converts the 11-pin banana plug on the Test Kit, to a 14-pin plug. This 14-pin plug, plugs into the Trip Unit Test Port, located on the face of the Trip Unit. The Magnum DS Test Kit Adapter (8779C02G04) is used to connect the Test Kit’s 11-pin plug to the Magnum DS Digitrip Trip Unit 14-pin test port. In additon, the Auxiliary Power Module (PRTAAPM), which is permanently connected to the Adapter, must be connected to a 120 V, 50/60 HZ source to supply control power to the Trip Unit.
