High Burden Application

These relays, supplied as high burden, are suitable for use in high

security circuit-breaker tripping circuits. The high burden provides

greater immunity to capacitance discharge currents, which can

result at the inception of an earth fault on battery wiring. This

makes the relays particularly suitable for use in distributed

tripping or control relay contact logic schemes, where the

initiating contact may be remote from the relay.

MVAJ 05

When configured for high burden applications, the burden is

either cut off at operation or is economised to a low figure

instantaneously.

Low Burden Application

These relays are suitable for general applications where the

initiating contact is located close to the relay. When configured

for low burden applications, by removing the external link from

terminals 22 and 24. the burden is either cut off during operation

or is economised to a low figure instantaneously.
