Oper<strong>at</strong>ion<br />
NFI core-balance transformers are used in conjunction with NZM circuit-breakers and<br />
switch-disconnectors. A secured control voltage, taken either directly from the input<br />
terminals of the NZM, or from an external source, is required to oper<strong>at</strong>e the electronic<br />
system of the residual-current relay. The electronic system of the residual-current<br />
relay issues the trip signal to the shunt release or undervoltage release of the NZM<br />
through a zero-voltage changeover contact. The switch then trips all poles in 0.2<br />
seconds or less. Fault signalling can be implemented via the auxiliary contact on the<br />
NZM. The built-in test button provides a simple means of functional testing, while an<br />
internal LED indic<strong>at</strong>es readiness for oper<strong>at</strong>ion. Monitoring is performed according to<br />
the oper<strong>at</strong>ing current principle. In the event of a power failure, the last oper<strong>at</strong>ional<br />
st<strong>at</strong>e is retained and is reapplied after voltage recovery.<br />
