JC3R-125 residual current device
TECHNICAL DATA
JC3R-125 residual current device specifications
The JC3R-125 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
JC3R-125 RCD waveform response selection
Specify the complete order code, circuit duty, installation conditions and required documents when requesting a JC3R-125 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
JC3R-125 RCD overcurrent coordination FAQs
Find answers about JC3R-125 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 3P+N at 400/415V. Confirm the neutral and test-circuit wiring, especially for a circuit without a neutral.
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 JC3R-125 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.
