Lsolating Switch JCH3-125 Main Switch Isolator 100A 125A
TECHNICAL DATA
JCH3-125 100A and 125A Main Switch Isolator Information
The W9 Group product title identifies JCH3-125 as a main switch isolator with 100A and 125A designations. Use JCH3-125 in the enquiry and confirm the offered current, poles, switching duty and installation drawing for that exact model.
The title identifies JCH3-125, while older body text identifies JCH2-125 and contains a different rating schedule. Confirm a JCH3-125-specific datasheet and nameplate before selection.

SELECTION GUIDE
Selecting JCH3-125 100A 125A main switch isolator for Your Installation
Use JCH3-125 as the enquiry reference and confirm the selected configuration against your circuit, connection and installation requirements.
Define the switching duty
Provide load type, supply voltage and required operating duty. Confirm the utilization category and permitted switching conditions.
Select current and poles
Match the ordered current and pole configuration to the circuit, including any neutral-switching requirement.
Coordinate fault protection
Specify the upstream protective device and prospective fault current. Request the manufacturer’s short-circuit coordination information.
Check enclosure and access
Confirm dimensions, terminal details, mounting and access for operation and maintenance. Request any locking instructions separately.

BUYER FAQ
JCH3-125 Main Switch Isolator Rating and Wiring FAQs
Find answers about JCH3-125 selection, configuration and ordering.
Is this isolator an automatic circuit breaker?
It is listed as a manual switch disconnector. Confirm separate overload and short-circuit protection; a manual switching function does not establish automatic fault tripping.
Which model should appear on the order?
Request the complete order code and nameplate confirmation from W9 Group. Use a matching model-specific datasheet and connection drawing throughout the specification.
How should I choose the current and pole arrangement?
Provide the circuit current, supply and neutral-switching requirement. Confirm the exact current option and conductor arrangement for the offered model.
Does a withstand rating establish load switching duty?
No. Confirm rated operating voltage and utilization category separately from insulation, impulse and short-time withstand data.
Can the JCH3-125 main switch isolator be locked for maintenance?
Confirm whether the selected JCH3-125 has a compatible locking arrangement, which operating positions can be secured and the required installation procedure.
Which installation documents should I request?
Request the terminal diagram, mounting dimensions, conductor limits, tightening instructions and applicable operating-duty schedule for the exact nameplate model.
What should I send for a JCH3-125 quotation?
Send the complete JCH3-125 designation, required configuration, quantity, destination market and documents needed. Ask W9 Group to confirm the offered item, price, minimum order quantity and delivery terms.
Send W9 Group the complete JCH3-125 designation, circuit or host-equipment requirements, quantity and destination market. Request the exact offered configuration and its matching technical documents.
