- Description
The Schneider Electric RM35LM33MW is a Harmony RM35L level control relay that detects liquid level via resistive probes in 3-phase-supplied installations and switches 2 C/O contacts rated 5 A. It runs from a universal 24-240 V AC/DC 50/60 Hz supply, offers an adjustable 0.1-5 second fault time delay, and mounts on 35 mm DIN rail.

Selection Notes
RM35LM33MW monitors liquid level via resistive probes on 3-phase-supplied installations, using the same LS/St/HS sensitivity scale (0.25 kOhm to 1000 kOhm) and 100 m probe cable limit as the other Harmony RM35 measurement relays, so probes sized for one RM35 part carry over to another. Its 0.1-5 s fault time delay is short enough for fast dry-run alarms, and the 2 C/O output at 5 A lets one contact drive an alarm circuit while the other trips the load.
