Earth Leakage Protective Relays
BRR, RRD and EL series
Earth leakage protective relays
I
Description
In the earth leakage relay the breaking
mechanism is omitted from the ELCB,
and the ZCT and earth leakage tripping
device are integrated into a common
body. These relays are available in both
instantaneous and time-delay versions.
Generally these relays are used in
conjunction with MCCB's, ACB's and
motor starters.
