Selecting a Type A or Type AC Residual Current Circuit Breaker
Specify the pole count, current, residual-current type, sensitivity, supply voltage and upstream protection when requesting a JCRD4-125 quotation from W9 Group.
Match supply and poles
The listed pole options are 4P. Confirm supply voltage, neutral arrangement and the manufacturer’s terminal diagram.
Choose type and sensitivity
Specify Type A or Type AC and the required residual-current sensitivity. Confirm the waveform and protection requirements of the circuit.
Coordinate overcurrent protection
Select a compatible MCB or fuse and request the manufacturer’s short-circuit coordination data. The RCCB does not replace overcurrent protection.
Confirm the offered current
The reviewed current choices include 25, 40, 50, 63, 80, 100 A. Confirm the complete model code and rating for the quoted unit.

Часто задаваемые вопросы покупателей
JCRD4-125 RCCB FAQs: 30mA Options and Overcurrent Coordination
Find answers about JCRD4-125 selection, configuration and ordering.
Is JCRD4-125 an RCCB or an RCBO?
It is listed as an RCCB: residual-current protection without integral overload and short-circuit protection. Use a coordinated MCB or fuse for those functions.
Which pole and supply arrangement is listed?
This model is listed as 4P. The voltage choices appear in the specifications; confirm the selected voltage and neutral connection diagram in the offered datasheet.
Which residual-current sensitivities are available?
W9 Group lists 30 mA, 100 mA and 300 mA options. Select the sensitivity for the required protection purpose and coordination.
How do I specify Type A or Type AC?
The source lists both options. State the connected equipment and required residual-current waveform response, and confirm the selected type in the quotation.
Does a 6kA figure mean the RCCB protects against overload?
No. A short-circuit figure does not establish integral overcurrent protection. Confirm the conditional short-circuit rating and required upstream protective device.
What installation details should be checked?
The source lists 35 mm DIN-rail mounting and IP20 protection. Confirm terminal sizes, busbar compatibility, connection instructions and enclosure requirements.
What is needed for a JCRD4-125 quotation?
Отправьте необходимую конфигурацию, количество, целевой рынок и требования к документации. Попросите компанию W9 Group подтвердить цену, минимальное количество заказа, наличие образцов и срок изготовления выбранной конфигурации.
