SELECTION GUIDE
How to Select an MCCB Shunt Trip Release by Control Voltage and Coil Duty
Specify the host breaker, release code, coil supply, command duration and reset requirements when requesting a Shunt Release quotation from W9 Group.
Identify the breaker and release
Provide the complete MCCB code and required shunt-release accessory code. Confirm the mounting and wiring interface.
Define the control supply
State the actual control voltage and AC or DC type. Confirm nameplate supply limits for the selected coil.
Specify command duration
Confirm whether the input is a pulse or maintained command and whether auxiliary cutoff or interlocking is required.
Check trip and reset behavior
Request the wiring diagram and reset procedure. Confirm how the trip command affects any motor mechanism and closing permission.

BUYER FAQ
MCCB Shunt Release FAQs: Remote Trip vs Closing and Undervoltage Release
Find answers about Shunt Release selection, configuration and ordering.
What does the MCCB shunt release do?
The target source describes an auxiliary device for remote tripping of the compatible breaker. Confirm the exact coil and host combination.
Is a shunt release the same as an undervoltage release?
Specify commanded tripping or voltage-loss protection as separate requirements. Confirm which release and control scheme the breaker needs; one name does not establish both functions.
Which coil voltage should I order?
The available text gives a relative operating range but not a complete orderable voltage schedule. Confirm the exact rated AC or DC supply and nameplate limits for the selected release.
Can the coil stay energized continuously?
Continuous duty is not established by the source. Confirm permitted command duration, coil duty, auxiliary cutoff and protective interlocks.
Can the shunt release remotely close the breaker?
Remote tripping does not establish a closing actuator. Confirm any separate motor mechanism, reset and closing-permission circuit.
What confirms compatibility and terminal assignment?
Use the full MCCB series and frame with the release code, mounting instructions and wiring diagram. Confirm reference terminals and the post-trip reset sequence.
What is needed for a Shunt Release 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.
