SELECTION GUIDE
Selecting a 2 Pole or 4 Pole Switch Disconnector
Specify the current, poles, supply voltage, load duty, enclosure and locking requirements when requesting a JCH2-125 quotation from W9 Group.
Choose the current rating
The table includes 32–125 A choices. Confirm the ordered current and its load-duty suitability.
Match poles and supply
Specify the required live and neutral isolation arrangement. Request the connection diagram for the selected pole version.
Check isolation and locking
Confirm contact indication, the locking accessory and the isolation procedure required by the installation.
Provide circuit protection
Coordinate a suitable breaker or fuse separately. Confirm load switching duty and short-circuit withstand data with W9 Group.

BUYER FAQ
Main Switch Isolator FAQs: Poles, Load Duty and Circuit Protection
Find answers about JCH2-125 selection, configuration and ordering.
Is JCH2-125 a circuit breaker?
It is listed as a main switch isolator / switch-disconnector. It does not provide overload or short-circuit trip protection.
What current ratings are listed?
The technical table lists 32, 40, 50, 63, 80, 100 and 125 A. Confirm the available order code and current marking.
Can I choose a 2-pole or 4-pole main switch?
Yes, the source lists 1P, 2P, 3P and 4P versions. Confirm the required supply and neutral isolation arrangement.
What utilization category is stated?
The supplier lists AC-22A. Confirm that the load duty and operating conditions are covered by the offered switch rating.
Does IP20 make the switch suitable for outdoor exposure?
Do not use IP20 as evidence of outdoor weather protection. Confirm the enclosure and environmental requirements for the installation.
Which installation documents are needed?
Request the dimensions, terminal and busbar details, locking instructions and connection diagram for the selected version. Confirm short-circuit withstand values because source sections differ.
What is needed for a JCH2-125 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.
