SELECTION GUIDE

JCB3-125 high current MCB selection

Specify the complete order code, circuit duty, installation conditions and required documents when requesting a JCB3-125 quotation from W9 Group.

01

Define the supply circuit

Provide the supply type, maximum circuit voltage and earthing arrangement. Confirm the required pole connection from the matching wiring diagram.

02

Coordinate current and release

Choose the ordered current using conductor and load duty. Request the exact trip curve and any installation-related derating.

03

Compare fault interruption

Provide the prospective short-circuit current. Confirm the breaking rating, operating voltage and applicable test standard together.

04

Check installation details

Request terminal limits, mounting dimensions, torque and accessory compatibility for the complete model code.

Before specifying JCB3-125: Confirm supply type, operating voltage, pole arrangement and trip curve using the exact order-code documentation.

BUYER FAQ

JCB3-125 MCB fault rating FAQs

Find answers about JCB3-125 selection, configuration and ordering.

Is JCB3-125 specified for AC or DC supply?

Confirm the exact supply-specific order code and rating schedule. The summary includes a DC voltage statement for a four-pole configuration, but does not establish the same voltage or supply rating for all variants.

Is every JCB3-125 supplied at the maximum current?

No. The supplier lists a range up to 125A. Confirm the individual current option and its trip curve for the intended conductor and load.

Can I use the same voltage on every pole option?

Confirm a separate voltage and wiring schedule for each pole configuration. Do not apply the four-pole voltage statement to fewer poles.

Does 10kA establish the required fault duty?

Confirm the voltage, test standard and selected configuration associated with the listed 10kA rating, then compare it with the prospective circuit fault current.

Does this MCB include residual-current protection?

Residual-current protection is not established by the listed overload and short-circuit functions. Confirm a separate RCD or an appropriate RCBO if that protection is required.

Which trip curve and mounting dimensions should be used?

These details are not established by the available summary. Request the matching curve, dimensions and terminal instructions from W9 Group.

What is needed for a JCB3-125 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.
