راهنمای انتخاب
Selecting an 18mm 1P+N Miniature Circuit Breaker
Specify the rated current, pole count, trip curve, operating voltage and board connection details when requesting a JCB3-40M quotation from W9 Group.
Match current to the circuit
The catalog covers 1–40 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. Request the selected time-current curve for starting-current and coordination checks.
Specify poles and supply
State the supply voltage and required 1P+N arrangement. Confirm the wiring diagram and terminal allocation.
Check the board space
Allow for the listed 18 mm single-module body and confirm terminal and busbar compatibility.

JCB3-40M MCB FAQs: Current, Trip Curve and Board Fit
Find answers about JCB3-40M selection, configuration and ordering.
What does JCB3-40M 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 JCB3-40M?
The target-model summary lists a 1–40 A range. Confirm the individual current rating and complete order code.
Which pole configurations are offered?
This page lists 1P+N. Confirm the wiring and neutral arrangement in the matching product drawing.
How do I specify the trip curve?
The matching features list B / C. 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.
