選定ガイド
Selecting a Capacitor Bank Contactor by Load and Coil Voltage
Specify the capacitor step capacity, system voltage/frequency, coil supply, switching sequence and mounting size when requesting a CJ19 quotation from W9 Group.
State the capacitor step
Provide the step capacity, system voltage and frequency. Request the matching model-specific capacitor-switching rating.
Check switching inrush
Confirm that the offered inrush-limiting arrangement is suitable for the bank configuration and switching sequence.
Choose the coil and controls
Specify the control-supply voltage and frequency together with the required auxiliary contacts.
Confirm size and mounting
Request the selected model’s dimensions and screw / rail fixing details. Confirm terminal capacity and protection coordination.

購入者のよくある質問
CJ19 Contactor FAQs: Inrush Current, Capacity and Mounting
Find answers about CJ19 selection, configuration and ordering.
What is CJ19 designed to switch?
The supplier lists low-voltage shunt capacitors used in reactive-power compensation equipment. It is a capacitor-switching contactor rather than a general protection device.
Why does capacitor switching need an inrush arrangement?
The source describes restraint of switching inrush for capacitor duty. Confirm the offered arrangement against the bank size and operating conditions.
Can I size CJ19 using only its thermal current?
No. Confirm the capacitor-switching capacity at the actual system voltage. A thermal-current row alone does not establish the permitted capacitor step.
What capacitor capacity can each model switch?
The source has a model and voltage matrix, but its units and series coverage are not sufficiently clear for a universal capacity claim. Confirm the manufacturer’s capacity table for the offered model.
Which coil voltage should be ordered?
Specify the actual control voltage and frequency, then confirm the coil code. The capacitor-bank supply and contactor-coil supply are separate selection inputs.
Does every CJ19 size use the same DIN rail?
No common fixing should be assumed. The page describes different screw and rail arrangements by size; confirm the mounting drawing for the chosen frame.
What is needed for a CJ19 quotation?
必要な構成、数量、配送先市場、および書類の要件を送信してください。W9 Groupに、選択した構成の価格、最小注文数量、サンプル、納期を確認していただくよう依頼してください。.
