Our new range of 17.5mm wide, DIN rail mount Type A Earth Leakage Relays have been designed for the smaller and more compact electrical control panels where space is tight. The “single module” size allows for use with distribution boards for monitoring single and three phase supplies.
Extremely simple to install and only require a supply to power them and external Core Balance Current Transformer. There are no user adjustments and 3 fixed trip sensitivity levels to choose from:
-
-
- 30mA (Model no. LELRF-0030)
- 100mA (Model no. LELRF-0100)
- 300mA (Model no. LELRF-0300)
-
Each variant has a very fast trip response time of <25ms and is fully complaint with IEC 60947-2/Annex M.
For simplicity, a single Test/Reset button allows the user to test the unit as well as reset after a trip event.
A SPDT relay output is configured to energise on trip allowing the unit to be used with external devices such as shunt trips.
