Can the amperage be changed on a Micrologic LX, LE, MX, ME, NX, NE, PX, or PE circuit breaker?
Issue:
Need to change the amperage or sensor on a legacy Micrologic electronic trip breaker
Product line:
Legacy Micrologic breakers
Resolution:
To change the amperage of a legacy Micrologic trip breaker, there are two options: 1) change out the rating plug or 2) adjust the long time pickup dial. For safety reasons, ONLY perform work and maintenance on de-energized equipment. There is a possibility of tripping the breaker during adjustments.
The rating plugs with their multiplier values are listed below. The multiplier is the factor to be applied to the sensor rating. Note that there is no restriction on interchanging the ARP rating plugs on LX, LE, MX, ME, NX, NE, PX or PE breakers.
