SELECTION GUIDE
Selecting an MCCB Auxiliary Alarm Contact for Position and Trip Indication
Specify the host MCCB model, required signal states, connection version, control voltage and input load when requesting a Auxiliary Alarm Contact quotation from W9 Group.
Specify the required signal
Define position feedback, defined trip indication or separate circuits. Request the state truth table before assigning control-system inputs.
Identify the exact host
Provide the complete MCCB model, frame, release and accessory position. Confirm the matching accessory code.
Match the control load
State control voltage, input current and load type. Confirm contact ratings and any minimum reliable switching load.
Choose the connection form
Select wiring leads or a terminal version. Confirm lead identification, terminal assignment and the reset procedure.

BUYER FAQ
MCCB Auxiliary Alarm Contact FAQs: Signal States and Host Compatibility
Find answers about Auxiliary Alarm Contact selection, configuration and ordering.
What does this MCCB auxiliary alarm contact report?
The native listing identifies an auxiliary-plus-alarm accessory. Confirm which terminals report position and which report a defined trip event using its exact contact diagram.
Is auxiliary position feedback the same as a fault alarm?
Specify which signal the circuit needs. Confirm whether each terminal follows main-contact position or a defined trip event; do not assume those states are interchangeable.
Does the accessory open or close the breaker remotely?
A feedback contact does not establish an operating actuator. Request the separate shunt release or motor mechanism if commanded opening or closing is required.
What NO / NC arrangement and contact rating can I use?
The exact arrangement and voltage-dependent rating must come from the selected accessory diagram and datasheet. Confirm the reference state, load category and control-input requirements.
Will it fit all MCCB frames?
No universal compatibility is established. Confirm the breaker series, frame, release, accessory position and complete accessory code.
Should I select wiring leads or terminals?
Choose the connection form for the panel wiring and service requirements. Confirm terminal identification, lead length where applicable, mounting and the procedure for checking each signal state.
What is needed for a Auxiliary Alarm 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.
