Instruction Book Page 28 Effective: February 2007 5-2.2 CONTACT EROSION INDICATOR The purpose of the contact erosion indicator is to monitor any erosion of the vacuum interrupter contacts. Contact erosion is, however, very minimal over time with Cutler-Hammer vacuum interrupters utilizing copper-chrome contact material.
Instruction Book Effective: February 2007 Page 29 Wipe and Stroke are thus related to each other. As the stroke increases due to the erosion of contacts, the wipe decreases. A great deal of effort has been spent in the design of all Cutler-Hammer vacuum breakers, in order to eliminate the need for field adjustments of wipe or stroke.
