選定ガイド
Selecting a 1–80A MCB by Pole Arrangement and B, C or D Curve
Specify the rated current, pole count, trip curve, supply voltage and required breaking capacity when you request a JCB3-80H quotation from W9 Group.
Choose the rated current
For JCB3-80H, match the ordered current to the circuit design and conductor protection requirements; the catalog range is 1–80 A.
Choose the trip curve
Specify B, C or D and request the corresponding time-current curve to assess starting current and coordination.
Match pole count and fault duty
State the number of poles and supply voltage. Confirm that the selected breaking rating meets the prospective short-circuit current.
Check mounting and connections
Request the terminal, busbar and mounting drawing for the ordered version before finalizing the distribution board.
