The Static Trip III consists of four models:

A standard feature of the Static Trip IIIC, IIICP, and IIICPX trip

units is an alarm output. Any measured parameter can be set to

activate the alarm based on threshold and time delay set points.

These units also include several logging functions for recording

trip events, pickup conditions, alarm activity, and min/max

measured values.

Static Trip IIIC, IIICP, and IIICPX trip units have added

communication ability. Metered parameters can be displayed

and configured locally on the BDU or remotely via the RS-485

communications port through the ACCESS system.
