The Style Number Identification Chart (Figure 1) illustrates the manner in which the relay style number is
determined. For example, if the style number were U3E-Z1P-B1C1F, the device would have the following
characteristics:
U - Three-Phase-and-Neutral sensing, 3-phase, 4-wire voltage restraint
3 - Sensing input range of 1.5 to 12.0 amperes for phase and 0.5 to 4.0 amperes for neutral
E - Normally open outputs
Z1 - Switch selectable time curves
P - Operating power derived from 125 Vdc or 120 Vac
B - Current operated targets
1 - One instantaneous element
C - Push-to-energize outputs
1 - Normally open auxiliary timed output relay
F - Semi-flush mounting
