RTC: ready to close signalling
contact
200 | © 2023 ABB | 1SDH001330R1002 - ECN000297030
The RTC contact indicates that the circuit-breaker is ready to receive a closing command.
The conditions necessary to allow the closing of the circuit-breaker are:
• circuit-breaker open
• springs charged
• absence of an opening command or of a lock in opening
NOTE: if the circuit-breaker is opened due to the tripping of the Ekip protection trip unit,
in order to allow closing, the Reset signal of the circuit-breaker must have been reset (press
the TU Reset pushbutton on the front panel).
The RTC is a "switching" contact type and is available in the standard version or in the versions for digital
signals.
