SELECTION GUIDE
How to Select a JCSD1-125 Contact by Signal Logic and Host Compatibility
Specify the host breaker model, required signal states, control voltage, monitoring load and accessory combination when requesting a JCSD1-125 quotation from W9 Group.
Choose the required signal
Use the defined automatic-trip indication for fault monitoring. Confirm which releases change the signal and how it resets.
Confirm the mechanical interface
Provide the exact MCB or RCBO order code and accessory stack. Confirm the left-side pin interface and permitted combinations.
Match the monitoring load
Request the contact voltage, current, load category and minimum switching requirements. Match these to the PLC input, indicator or relay circuit.
Check the state diagram
Obtain terminal numbering and the contact truth table. Confirm manual operation, protective trip and reset behavior during commissioning.

BUYER FAQ
JCSD1-125 Contact FAQs: Position Feedback, Trip Indication and Reset
Find answers about JCSD1-125 selection, configuration and ordering.
What signal does the JCSD1-125 provide?
The target description specifies indication after automatic release of a compatible MCB or RCBO due to overload or short circuit. Confirm the terminal diagram and the state table for the supplied host combination.
How does this differ from a position contact?
A position contact reports the contact position. This alarm listing describes indication after automatic overload or short-circuit release. Confirm the exact triggering events and reset sequence.
Which breakers can accept the accessory?
The functional description lists MCBs and RCBOs with left-side pin mounting. Confirm the exact compatible breaker models and accessory combinations; the mounting description is not universal compatibility.
What are the contact count, terminal numbers and NO / NC states?
The available target text does not establish a complete contact diagram. Request the terminal drawing and state table rather than inferring the contact count from the model digits.
Can the accessory switch the main load?
This is a signaling accessory. Confirm its control-contact electrical rating and intended load; do not use the host breaker rating as the accessory contact rating.
Can it trip or close the breaker remotely?
The listed function is indication. Commanded tripping or closing needs a separately specified release or operating mechanism. Confirm the required combination with W9 Group.
What is needed for a JCSD1-125 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.
