選定ガイド
How to Select a 1 Pole to 4 Pole MCB
Specify the rated current, pole count, trip curve, operating voltage and board connection details when requesting a JCB3-80M quotation from W9 Group.
Match current to the circuit
The catalog covers 1–80 A. Confirm the required current step and coordinate it with the circuit conductors and load.
Choose the trip curve
The reviewed matching features list B / C / D. Request the selected time-current curve for starting-current and coordination checks.
Specify poles and supply
State the supply voltage and required 1P / 2P / 3P / 4P arrangement. Confirm the wiring diagram and terminal allocation.
Check the board space
Request dimensions and busbar details for the selected pole version before finalizing the board.

Find answers about JCB3-80M selection, configuration and ordering.
What does JCB3-80M protect against?
The product is listed for overload and short-circuit protection. Residual-current protection requires a suitable additional device or an RCBO configuration.
Which currents are listed for JCB3-80M?
The target-model summary lists a 1–80 A range. Confirm the individual current rating and complete order code.
Which pole configurations are offered?
This page lists 1P / 2P / 3P / 4P. Confirm the wiring and neutral arrangement in the matching product drawing.
How do I specify the trip curve?
The matching features list B / C / D. Select using the load starting current and protective coordination, and request the corresponding curve.
Is the listed 6kA rating suitable for every board?
The breaking rating must meet the prospective short-circuit current at the installation point. Confirm the applicable voltage and rating on the supplied datasheet.
How is this MCB installed?
The source lists 35 mm DIN-rail mounting. Confirm the terminal capacity, busbar type, dimensions and tightening instructions for the ordered version.
