LOVATO Electric expands its range of earth leakage relays with two new flush-mounted versions: R1D23072, Type A 72×72 mm and RM2PDB230, Type B 96×96 mm, with display.
R1D23072 is a Type A earth leakage relay with 1 tripping threshold. It integrates 1 relay output with changeover contact and can be powered with an auxiliary voltage of 110–230 VAC. It is housed in a 72×72 mm enclosure for panel mounting. On the front, dip-switches are available for setting the tripping threshold and the related time delay, along with control buttons featuring relay TEST and alarm RESET functions. Inside the package, a cover is supplied as standard that increases the front protection degree from IP40 to IP52.
RM2PDB230 is a Type B earth leakage relay with 2 tripping thresholds. Housed in a 96×96 mm enclosure, it features a multicolor backlit LCD display for reading the leakage current, both AC and DC components. It requires an auxiliary supply of 80–250 VAC / 120–250 VDC and integrates 2 relay outputs with changeover contacts. On the front, TEST and RESET buttons are available; these functions can also be controlled remotely via dedicated digital inputs. RM2PDB230 also includes an event log for recording fault current trips, an autotest function to verify toroid connection, a selectable third or twenty-first harmonic filter, and password protection for settings.
