Selecting JCB1-125 miniature circuit breaker for Your Installation
Use JCB1-125 as the enquiry reference and confirm the selected configuration against your circuit, connection and installation requirements.
Choose the rated current
For JCB1-125, specify the circuit design current and conductor protection requirements. Ask W9 Group to confirm the available current steps for the exact order code.
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.
