Scope note: series pages are still being prepared. The hub uses page anchors until each family page has rating tables, variants and model-level files ready for publication.
Application fit
Line Isolation, Load Switching, Fuse Protection and Bypass Applications.
Locate the duty point first: visible isolation, load sectionalizing, transformer branch protection, maintenance bypass, grounding or cabinet isolation.
Visible isolation
Outdoor disconnect switches for line isolation
For feeder, substation or line positions where the main requirement is visible open isolation before maintenance.
Load sectionalizing
Outdoor air break switches for overhead lines
For overhead distribution line points that need outdoor switching, sectionalizing or simple load-break review.
Transformer branch
Fuse disconnect switches for branch protection
For transformer branches and feeder taps where fuse protection and visible isolation are selected together.
Maintenance isolation
Bypass, earthing and indoor disconnects
For bypass paths, grounding points and cabinet isolation positions that depend on the maintenance sequence.
Duty and rating comparison
Compare Voltage Range, Duty Boundary and RFQ Inputs.

Switch Body, Operating Mechanism, Mounting and Interlock Package.
For disconnect switch selection, family selection is only the first layer. The quote still needs mechanism, mounting, interlock and drawing inputs before model-level confirmation.
Switching Package Architecture
Start with the selected switch family, then lock the operating and installation package used for drawings, packing and inspection.

Page reviewMaintained by XIYA POWER product documentation
Updated June 26, 2026. The page routes switching and isolation inquiries to the correct product family before model-level quotation.
01Family first
Outdoor disconnect, air break, fuse disconnect, earthing, bypass and indoor switch disconnector decisions stay separate.
02Line position
The topology section explains where each family sits in the switching chain.
03File-backed review
Photos, catalog pages and instruction files support the current family comparison.
04RFQ ready
Use voltage, duty, drawings, quantity and destination standard before final price review.
RFQ Checklist for Disconnect, Air Break and Fuse Disconnect Switches.
Useful RFQ details include voltage, rated current, isolation or switching duty, fuse or grounding function, operating mechanism, mounting photos, drawings, quantity, destination country and utility standard.
What does this Disconnect Switches selector cover?
It covers outdoor disconnect switches, outdoor air break switches, fuse disconnect switches, earthing switches, bypass disconnectors and indoor disconnect switches used for line isolation, sectionalizing, grounding and maintenance switching decisions.
What is the difference between an outdoor disconnect switch and an air break switch?
Use an outdoor disconnect switch when the main requirement is visible no-load isolation. Use an outdoor air break switch when the line point also needs air break switching or sectionalizing within the selected rating and operating method.
When should a buyer choose a fuse disconnect switch?
Choose a fuse disconnect switch when fuse protection and visible isolation belong at the same transformer branch, feeder tap or outdoor line protection point. Send fuse carrier or fuse link requirements with the voltage and current class.
When are earthing switches and bypass disconnectors reviewed?
Review earthing switches when the operating sequence needs a dedicated grounding point. Review bypass disconnectors when a recloser, breaker or switching device needs a service bypass path for maintenance.
What information is needed before XIYA POWER can quote a disconnect switch?
Send voltage class, rated current, line position, isolation or switching duty, operating mechanism, mounting photos or drawings, quantity, destination country and any utility standard requirement.
Should individual models be selected on the selector page?
No. The selector should narrow the product family first. Model selection comes after voltage, duty, installation drawings and document requirements are known.
