SELECTION GUIDE
How to Select a JC3RH 2 Pole or 4 Pole RCD for Earth-Leakage Protection
Specify the waveform type, pole arrangement, rated current, sensitivity, supply voltage and backup protection when requesting a JC3RH quotation from W9 Group.
Choose the residual waveform type
Specify Type A or Type AC according to the connected equipment and installation rules. Confirm the exact suffix and response characteristics.
Separate current from sensitivity
Select the load-current rating and residual-current sensitivity independently. Confirm the protective purpose and coordination of the chosen sensitivity.
Match the poles and supply
Use the published pole-specific voltage options and request the neutral-terminal and supply-connection drawing for the exact version.
Coordinate backup protection
Request the conditional short-circuit data and associated upstream device. Confirm selectivity using trip-time information instead of relying on a suffix alone.

BUYER FAQ
JC3RH RCD FAQs: Type A vs AC, Sensitivity and Overcurrent Coordination
Find answers about JC3RH selection, configuration and ordering.
What does the JC3RH residual current device protect against?
Its stated function is earth-leakage protection. The source cites the residual-current device standard; the candidate does not claim integrated overload or short-circuit tripping from contradictory legacy wording.
Which load-current and sensitivity options are listed?
The target table lists 25, 40, 50, 63, 80 and 100 A, with 30 mA, 100 mA and 300 mA residual-current sensitivity options. Confirm the exact offered combination.
How do I choose Type A or Type AC?
Select the waveform response required for the connected load and local installation rules. Confirm the full device type from a matching datasheet; Type A is not an assumed smooth-DC detection rating.
What are the pole and operating-voltage options?
The table lists 2-pole versions at 230/240 V and 4-pole versions at 400/415 V. Confirm the supplied pole version, neutral terminals and wiring diagram.
Does the S suffix prove time-delayed selective operation?
The schedule lists several waveform and suffix variants but does not establish the exact time-current behavior of every listing. Confirm the delay class, trip-time curve and upstream/downstream coordination.
Does it replace an MCB or other overcurrent protective device?
Residual-current protection and overcurrent protection serve different duties. Confirm the separate overload and short-circuit device and the tested backup combination for the installation.
What is needed for a JC3RH quotation?
Send the required configuration, quantity, destination market and document requirements. Ask W9 Group to confirm price, minimum order quantity, samples and lead time for the selected configuration.
