選定ガイド
How to Select an MCCB Undervoltage Release by Supply and Trip Thresholds
Specify the host MCCB, release code, rated control supply, trip thresholds, delay and reset requirements when requesting a Undervoltage Release quotation from W9 Group.
Identify the required function
Specify voltage-loss opening and closing-inhibition requirements. Confirm whether an instantaneous or delayed release is needed.
Select one control supply
Match the release coil to the actual AC or DC supply. Confirm the nameplate rating rather than treating voltage options as a universal input.
Confirm thresholds and timing
Request the release-specific drop-out, pickup and closing-permission limits with the applicable delay.
Verify the host and wiring
Provide the complete MCCB code and request the accessory mounting diagram, terminals and reset instructions.

購入者のよくある質問
MCCB Undervoltage Release FAQs: Voltage Restoration and Closing Permission
Find answers about Undervoltage Release selection, configuration and ordering.
Is this an undervoltage release or a feedback contact?
The native title uses contact wording, but the functional body describes undervoltage tripping and closing inhibition. Confirm the release code and function in the quotation.
What happens when the control voltage falls?
The source describes breaker opening as the control supply falls and prevention of closing at sufficiently low supply. Confirm the selected release thresholds and time response.
What control voltage options are available?
The native listing names AC and DC choices. Confirm the exact orderable voltage, frequency where applicable and release nameplate before selecting a coil.
Is an undervoltage release interchangeable with a shunt release?
Confirm the required operating principle and compatible accessory. Voltage-dependent release and commanded shunt tripping use different control requirements.
Does voltage restoration automatically close the breaker?
Closing permission does not by itself establish automatic reclosing. Confirm the breaker mechanism, reset and complete closing-control scheme.
Can it provide a delayed trip?
No universal delay option is established here. Request the required delay characteristic and confirm the exact accessory, wiring and supply arrangement.
