Description
The Model 2742 3-Phase Over/Under
Current Monitor is designed to monitor the current level of
a 3-phase line or to compare the currents of three single-phase
lines.
The Model 2742 is factory-set
as an over-current monitor; that is, if one or more current
inputs rises above the trip level, the internal relay will
de-energize. Adding a wire between the UNDER CURRENT terminals
on the case will cause the Model 2742 to sense a decrease
of one or more current inputs. An adjustable trip delay
of 0.2 to 20 seconds will prevent nuisance tripping. The
current trip point is adjustable from 1 to 5 amps, and matching
current transformers are available to extend the current
range of the monitor.
The Model 2742 will automatically
reset when the current fault is corrected. An external manual
reset can beadded by installing a normally closed switch
between the terminals marked RESET.
