AL-X3 Alarm Auxiliary Contact

1. Compliant standards

IEC60947-5
 

2. Compliant certification

CE
 

3. Major function

To be assembled with the circuit breaker to achieve signal indication over long distance for open/close status of the circuit breaker and alarm.
 

4. Parameters and performance

Rated operation currents under different working voltages:


 

Action characteristics: Figure 1 shows the wiring diagram for auxiliary contact. When the auxiliary contact is open, terminals 91 and 94 is connected; When the auxiliary contact is closed, terminals 91 and 92 is connected. When the alarm auxiliary contact is closed, and manually open with the handle, terminals 91 and 92 shall still be connected; when the alarm auxiliary contact is closed, and the assembled circuit trip open due to error, terminals 91 and 92 shall be open, and terminals 91 and 94 shall be connected; Life: Operating life of alarm auxiliary contact is ≥ 10000 cycles.
