MCCB auxiliary contact
TECHNICAL DATA
MCCB auxiliary contact specifications
W9 Group lists this MCCB auxiliary contact for remote indication of the breaker’s ON or OFF/tripped status through an auxiliary circuit. Select the contact using the host frame and the required signaling duty; the contact does not carry the breaker’s main load current.

BUYER FAQ
MCCB auxiliary contact signaling and compatibility FAQs
Find answers about MCCB auxiliary contact selection, configuration and ordering.
What does this contact indicate?
The source describes remote indication of the breaker’s ON or OFF/tripped state. Confirm the exact contact sequence for manual opening, fault trip and reset.
Which accessory codes and host frames are listed?
The original table lists AX-125, AX-250 and AX-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.
What is needed for a MCCB auxiliary contact quotation?
Send the required configuration, quantity, destination market and document requirements. Ask W9 Group to confirm price, minimum order quantity, samples and lead time for the selected configuration.
