The AUX 4Q contacts signal the open/closed state of the circuit-breaker.
These are "switched" contacts and are available in three types:
• four standard contacts
• four digital signals (low power)
• two standard contacts (Q1-Q2) + two digital signals (Q3-Q4)
NOTE: The standard AUX 4Q contacts are always included in the circuit-breakers
The following table provides information on the electrical characteristics:
