Auxiliary contacts. Auxiliary electrical components are combined with iC60 circuit breakers, iID residual current circuit breakers, iSW-NA remotely tripped disconnect switches, RCA remote controls, and ARA automatic make contacts; they provide trip or remote indication of their position (open/closed/ tripped) in the event of a fault. Tripping auxiliary components:. iMN: undervoltage release iMNs: undervoltage release with delay iMNx: undervoltage release, independent of supply voltage iMX: shunt release IMX + OF: shunt release with NC/NO contact. Indicator auxiliary components:. iOF: normally closed/normally open contact iSD: fault indication contact IOF/SD+OF: normally closed/normally open contact and switchable OF or SD contact.
