MCCBの低電圧リリーフ

The MCCB undervoltage release is offered by W9 Group for voltage-dependent breaker opening and closing permission. The native listing calls it an under-voltage contact, while the functional description identifies a tripping device. Confirm the exact release code, rated control supply and operating thresholds for the compatible MCCB. Request the selected configuration and matching technical documents from W9 Group.

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.

01

Identify the required function

Specify voltage-loss opening and closing-inhibition requirements. Confirm whether an instantaneous or delayed release is needed.

02

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.

03

Confirm thresholds and timing

Request the release-specific drop-out, pickup and closing-permission limits with the applicable delay.

04

Verify the host and wiring

Provide the complete MCCB code and request the accessory mounting diagram, terminals and reset instructions.

Before specifying Undervoltage Release: Confirm the exact accessory identity and control-voltage thresholds. Do not treat closing permission as a guaranteed automatic-reclosing function.

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.
