FAQs

What is the main purpose of the AL-X1 Alarm Auxiliary Contact?

It provides remote indication of the circuit breaker’s operating state, signaling when it has tripped due to overload or short-circuit conditions

Which circuit breakers can the AL-X1 be used with?

The AL-X1 is designed to assemble directly with NXB-63 and NXB-40 series circuit breakers

How does the AL-X1 differentiate between manual operation and fault tripping?

When manually opened, 91–92 remain connected, but if a fault occurs, 91–92 open and 91–94 connect, triggering an alarm output.

How is the AL-X1 installed?

It attaches to the left side of the circuit breaker and mounts on a TH35-7.5 DIN steel rail, as shown in the assembly diagram (page P-124).

What ensures the AL-X1’s durability and reliability?

It meets IEC60947-5 standards, is CE and RoHS certified, and operates reliably for over 10,000 cycles under rated voltage and current conditions
