On the front of ABB circuit breakers with an electronic trip unit, are a group of dip switches. For demonstration purposes, I will be using the PR221DS dip switch set up. This offers a protection against overloads with a long inverse time delay, and short circuits with either an instantaneous or an inverse time delay trip.

addition to the .4, so if I have the first two switches of .04 and .08 up, then my overloadthreshold would .52 or 52 percent of the maximum current rating. I can also set the trip curvetime delay with the t1 dip switch here. This is set for 6 times the trip threshold. Mynext set of dip switches is for setting either a short time delay with S or an instantaneoustime delay with I. When the S function is selected, the dip switches at T2 will determinewhether the trip time is set to 1/10th of a second or a quarter of a second. The dipswitches in the middle will determine the short circuit threshold. This can be from1 to 10 times the maximum current rating of the circuit breaker. My last dip switcheson the right are for setting the neutral. This can be turned on or off and can be set
