Accessories for circuit-breakers

Auxiliary position contacts - AUP (Fig. 02A/B)
When the circuit-breaker is a withdrawable version, the position of the mobile part can be signalled
electrically by accessorizing the fixed part with one of the following signalling contact units:

Ready to close signalling contact - RTC (Fig. 03)
The ready to close signalling contact – RTC – indicates that the circuit-breaker is ready to receive the closing
command. The circuit-breaker is ready to close when the following conditions have been met:
• circuit-breaker open
• springs loaded
• no opening command or locks on the opening command
• circuit-breaker reset following tripping of Ekip protection trip unit
• YU energized.
