PRODUCT SELECTOR
Find the Right MV Switchgear for Your Project
Select by system voltage, insulation type, rated current and application. Final configuration is confirmed against your SLD, BOQ and project specification.
Step 1 — Select System Voltage
11/12kV Systems
Typical utility, industrial, compact-substation and infrastructure distribution.
QCL-12 Gas-Insulated RMU
XGN15-12 Air-Insulated RMU
QCG-12 Solid-Insulated RMU
20/22/24kV Systems
For 20–24kV distribution networks, renewable plants and project substations.
33/35/36/40.5kV Systems
For higher-voltage distribution, substations, mining and renewable collection networks.
Step 2 — Compare Product Types
| Requirement | Recommended Product | Typical Fit |
|---|---|---|
| Compact sealed gas-insulated solution | QCL-12 / QCL-24 / QCL-40.5 | Utility, EPC, solar, BESS, industrial and infrastructure projects |
| Air-insulated metal-enclosed RMU | XGN15-12 | Conventional indoor distribution and compact substations |
| SF6-free option for confirmed projects | QCHB-12 or QCG-12 | Projects with environmental or insulation-medium requirements |
| Integrated MV + transformer + LV package | YB Compact Substation | Industrial, renewable, infrastructure and utility distribution |
| Vacuum switching component | QCDL Indoor VCB | Medium-voltage switchgear assemblies and replacement projects |
| RMU load switching or transformer feeder | FLN36-12 / 24 / 35 | Three-position load-break switch or switch-fuse configuration for compact MV distribution |
Step 3 — Match Rated Current and Application
630A Distribution
Common for RMU feeder, transformer protection and secondary distribution. Confirm short-circuit level and functional-unit arrangement.
1250A and Above
For higher-load feeders, bus couplers and selected GIS/MV switchgear projects. QCL-40.5 configurations can cover 630/1250/2500/3150A subject to project confirmation.
Project-Specific Configuration
C, V, F, PT and metering functions are selected from the approved SLD. Protection, CT/VT and cable interfaces are confirmed during engineering review.
Information Needed for Final Selection
Electrical
Rated voltage, frequency, rated current, short-circuit level, busbar rating and insulation requirements.
Configuration
SLD, functional units, incoming/outgoing feeders, protection scheme, metering and cable entry.
Project
Application, installation environment, quantity, standards, drawings, documentation and delivery requirements.
Engineering note: This selector provides a preliminary recommendation. Final equipment selection must be confirmed using the project SLD and technical specification.
