SELECTION GUIDE
How to Select a JC3RH-B Type B RCCB by Poles, Current and Sensitivity
Specify the complete order code, load type, poles, supply voltage, current, sensitivity and backup device when requesting a JC3RH-B quotation from W9 Group.
Identify the leakage waveform
Check the load manufacturer requirements for smooth-DC and frequency-dependent residual currents. Confirm the Type B response envelope for the exact device.
Match poles and neutral wiring
Specify 1P+N or 3P+N and the actual supply voltage. Request the neutral-terminal, supply and load connection diagram.
Choose current and sensitivity
Select rated current and residual-current sensitivity separately. Confirm the protection objective and upstream/downstream trip-time coordination.
Check backup and application rules
Request the permitted backup protective device and conditional short-circuit data. For inverter or charging circuits, include the equipment protection specification.

BUYER FAQ
JC3RH-B Type B RCCB FAQs: Smooth DC, Inverter Loads and Selectivity
Find answers about JC3RH-B selection, configuration and ordering.
What does Type B mean on the JC3RH-B RCCB?
Here Type B describes the residual-current waveform response, including smooth DC in the supplier description. It is different from the B overcurrent trip curve used to describe an MCB.
Which current and sensitivity options are listed?
The target table lists 25 A, 40 A, 63 A, 80 A and 100 A, with residual-current sensitivity choices of 0.03 A, 0.1 A and 0.3 A. Confirm the selected combination.
Which supply and pole configurations are available?
The table lists 1P+N at 230/240 V AC and 3P+N at 400/415 V AC, with a rated frequency of 50 Hz. Confirm the offered configuration and neutral connection diagram.
Can I use it with an inverter, rectifier or charging circuit?
The supplier discusses nonlinear loads and smooth-DC leakage. Confirm the equipment maker requirements, residual-current spectrum, local installation rules and exact-model response data; this is not a universal application approval.
Does the RCCB include overload and short-circuit protection?
The target identifies an RCCB and cites residual-current standards. Confirm a separate overcurrent protective device and the specified conditional short-circuit arrangement; do not interpret conditional capacity as integrated overcurrent protection.
Does the BS suffix guarantee selective or time-delayed tripping?
A suffix alone is insufficient. The available shared schedule does not establish a distinct selective curve for every model. Confirm the exact delay class and trip-time data before coordinating devices.
What is needed for a JC3RH-B 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.
