Ready to close signaling contact - RTC The ready to close signaling contact – RTC – indicates that the circuit-breaker is ready to receive the clos- ing command and is available only for the XT7 M. The circuit-breaker is ready to close when the following conditions are fulfilled: • the circuit-breaker is open • the springs are loaded • there are no opening command or locks on the opening command • the circuit-breaker is reset following tripping of the Ekip protection trip unit.

Mechanical signaling of tripping the protection trip unit - TU Reset XT7 M circuit-breakers are always equipped with a mechanical device that signals the tripping status of the protection trip units. After the Ekip trip unit has been tripped due to an electrical fault, the signaling device clearly indicates the tripping status on the front of the circuit-breaker. The circuit-breaker can be reset only after the signaling pushbutton has been restored to its normal operating position.
