MCCB trip alarm contact specifications
W9 Group lists this MCCB trip alarm contact for signaling a compatible breaker trip event. Confirm the events that operate the contact and its reset sequence using the exact accessory diagram; an alarm contact does not itself provide the breaker’s protection function.

구매자 FAQ
MCCB trip alarm contact signaling and compatibility FAQs
Find answers about MCCB trip alarm contact selection, configuration and ordering.
What does this contact indicate?
The source describes signaling when the host breaker trips. Confirm which trip events operate the contact and how the indication differs from manual switching.
Which accessory codes and host frames are listed?
The original table lists AL-125, AL-250 and AL-400 with frame associations. Confirm the complete host model, mounting position and compatible order code.
Can it switch the breaker’s main load?
Treat the accessory as a signaling contact and confirm its contact-duty rating. The host breaker’s main current rating is not the accessory’s switching rating.
How should I choose between AC and DC signaling circuits?
Provide the signaling supply, circuit current and load type. Request the matching contact rating and terminal diagram; do not transfer an AC rating directly to a DC control circuit.
Are normally open and normally closed terminals identified?
Request the exact terminal and contact-state diagram, including the state before operation, after a trip and after reset. The contact arrangement must match the control logic.
Does the contact include a remote trip or motor mechanism?
No such mechanism is established by this signaling accessory description. Confirm any separate shunt release, motor operator or controller required by the system.
