JC3RS residual current device
TECHNICAL DATA
JC3RS residual current device specifications
The JC3RS residual current device is listed by W9 Group for residual-current protection. Choose the waveform response, sensitivity, current-carrying rating and pole arrangement separately. Coordinate separate overload and short-circuit protection rather than treating an RCD as an RCBO.

SELECTION GUIDE
JC3RS RCD waveform response selection
Specify the complete order code, circuit duty, installation conditions and required documents when requesting a JC3RS quotation from W9 Group.
Choose the waveform response
Specify the connected equipment and expected residual-current waveform. Confirm the exact response type and any delay suffix.
Coordinate sensitivity and rated current
Choose the required residual-current threshold separately from the current-carrying rating. Confirm both in the ordered version.
Coordinate upstream protection
Request the manufacturer’s backup overcurrent and short-circuit coordination requirements for the actual supply and prospective fault level.
Plan neutral and test wiring
Request the exact line, neutral and test-circuit diagram. Confirm pole configuration, supply terminals and enclosure integration.

BUYER FAQ
JC3RS RCD overcurrent coordination FAQs
Find answers about JC3RS selection, configuration and ordering.
Does this RCD provide overload protection?
A residual-current device is not a substitute for overcurrent protection. Confirm the required upstream protective device and coordination schedule for the selected version.
How do Type A and Type AC differ?
Type AC addresses sinusoidal AC residual current; Type A additionally addresses pulsating DC residual current within its specified scope. Confirm the type required by the connected equipment; neither label establishes Type B coverage.
Are rated current and residual-current sensitivity the same?
No. Rated current concerns the device’s current-carrying duty, while sensitivity concerns its residual-current operating threshold. Confirm each independently in the offered version.
Which pole arrangement is listed?
The original table lists 1P+N and 3P+N arrangements. Confirm the corresponding voltage, neutral connection and test-circuit requirements for the selected version.
Can I use the RCD without a neutral connection?
Request an approved wiring arrangement for the exact unit and supply. Test-circuit operation may depend on the connection; do not improvise resistors or transfer another model’s diagram.
What do the G and S suffixes establish?
The original schedule includes G and S suffix variants. Confirm the actual delay, selectivity and waveform characteristics from the exact version’s documentation before coordinating upstream and downstream devices.
What is needed for a JC3RS 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.
