MCCB Undervoltage Release Voltage and Compatibility FAQs
Find answers about MCCB undervoltage release selection, configuration and ordering.
How does an undervoltage release operate?
It responds to a low control-supply condition through the compatible breaker mechanism. Confirm the precise dropout, closing-permission and reset characteristics for the ordered coil.
Is it the same as a shunt trip release?
No. An undervoltage release responds to its supply condition; a shunt release operates from an applied trip command. Confirm the operating principle required by the control system.
Which voltage version should be ordered?
Provide the exact AC or DC control supply and request the corresponding order code and nameplate. Confirm the voltage schedule with W9 Group before energizing the coil.
Does the accessory fit every MCCB?
Host compatibility is not universal. Confirm the full breaker model, frame, mounting position and any other installed accessories.
Will restoring the supply automatically reclose the breaker?
Closing permission and automatic reclosing are different functions. Confirm the required reset sequence and any separate motor mechanism or controller; supply recovery alone does not establish remote closing.
Which timing and wiring details are needed?
Request the coil wiring, permitted energization conditions, any delay function and the opening/reset sequence for the exact accessory version.
What should I send for a MCCB undervoltage release quotation?
Send the complete MCCB undervoltage release designation, required configuration, quantity, destination market and documents needed. Ask W9 Group to confirm the offered item, price, minimum order quantity and delivery terms.
