1. Overcurrent setting potentiometer
2. Spring for clip-on mounting on 35 mm/1.38 in. ⍽ rail
Operating Principles for RM17JC00MW
Control relay RM17JC00MW is:
- equipped with an integrated current transformer
- fault signaling is by LED
An adjustable time delay on threshold crossing, provides immunity to transients, and helps prevent spurious triggering of the output relay
Overcurrent detection
- Relay RM17JC00MW controls overcurrent.
- The relay closes when the current exceeds the threshold setting on the front panel and opens when it drops below the threshold minus the hysteresis.
- When terminal Y1 is linked to A1 (+), the output is reversed. The relay opens when the current exceeds the threshold setting on the front panel and closes again when it drops below the hysteresis value.
