1. Introduction to the Power Xpert® Release trip unit
PXR TRIP UNITS FOR POWER DEFENSE MOLDED CASE CIRCUIT BREAKERS MN012007EN June 2018 www.eaton.com
1.3 Health monitor
The PXR 20D and 25 trip units utilize an innovative algorithm to determine a health status.
The health status is continuously updated as overloads and interruption events occur.
To view the factors that affect the health monitor, select the “Diagnostics” menu. The
summary screen shown below is 100% of life with all four bars shaded. Each bar is
approximately 25% of breaker health according to the algorithm. As the life is decreased,
the shading in the leading bars will disappear. An alarm will be generated at 25% of health
remaining.
Since circuit breaker health includes more than just contact wear, other screens in the diag-
nostics menu will indicate the factors that go into the health calculation.
