Our 12~24kV indoor earthing switch (7S-JDKG) is a safety protection device, compatible for Schneider SM6 cubicle retrofit. It delivers reliable earthing protection for equipment power-off maintenance inside high-voltage switchgear, not for load current interruption.
Field engineers handling MV cubicle retrofits often struggle to source earthing switches that perfectly fit ageing SM6 switchgear. Our XiziEnergy 7S-JDKG medium voltage earthing switch is engineered for direct 12kV & 24kV panel replacement, with custom machining to match your existing cubicle dimensions.
Many clients come to us to upgrade existing Schneider Electric SM6 switchgear. Our engineering team will go through your original equipment data carefully. We cross-reference cabinet mounting layout, operating linkage interface and electrical performance figures to see if we can supply a matching replacement variant. Besides this 12/24kV earthing model, we also offer the 7S-JDKG 35kV SF6 load break switch for higher voltage cubicle renovation projects.
Critical note: We have to verify compatibility against your exact switchgear model and functional unit before order confirmation. A matching rated voltage alone never guarantees proper fit or safe, reliable operation.
If you need spare earthing switches for existing panels, or selecting hardware for a brand-new medium voltage build, sharing original part numbers and site installation photos helps our team cut down technical review time significantly.

When replacing the earthing switch fitted inside Schneider Electric SM6 medium voltage switchgear, always start evaluation from the original cabinet configuration.
SM6 cubicles cover a wide range of functional units. Each carries unique mechanical interfaces, operating linkages and interlock sequences. Never pick a replacement earthing switch based solely on voltage rating. The new unit must integrate smoothly with your whole existing assembly.
Identify the exact SM6 series, cubicle type and functional unit. Whenever possible, send us the old earthing switch part number, switchgear nameplate photos and original technical drawings. These documents help our engineers match all mechanical and electrical requirements needed for your retrofit job.
Check mounting hole locations, overall footprint, phase spacing, contact position and available installation clearance. Even with identical rated voltage, mismatched mounting geometry or contact alignment will prevent the replacement earthing switch from fitting correctly into your cubicle.
Inspect operating shaft size, coupling style, handle rotation direction, operating travel distance and mechanical connection interface. The new earthing switch must move freely inside your existing cabinet assembly. Do not reuse your old operating handle or mechanism without prior technical validation.
Confirm rated voltage, insulation class, short-time withstand current & duration, peak withstand current and short-circuit making capacity where required. The selected ratings need to align with your switchgear design and prospective fault conditions at site.
Review mechanical interlocks and required operating sequence between the earthing switch and other switching devices mounted inside the panel. The replacement unit must preserve all original safety interlock functions. Installation, function testing and commissioning should follow approved equipment manuals and local site safety protocols.
Drop-in replacement cannot be guaranteed for every SM6 setup without a complete technical review.
Our XiziEnergy engineering team analyses your equipment information and checks whether the 7S-JDKG, or a slightly modified version, meets your mechanical interface and electrical performance needs.
Please share the original switchgear model, old earthing switch details, site installation photos and dimensional drawings if you have them available.
Schneider Electric and SM6 are referenced only for compatibility assessment. XiziEnergy operates as an independent component supplier. This product is not OEM Schneider hardware, nor an officially authorised OEM replacement unless clearly stated within formal written documentation.
Once rating verification and configuration confirmation finish, the 7S-JDKG suits these project types:
Each site application needs careful review against switchgear design, site operating procedures and local electrical safety standards.
Earthing switches act as critical safety components within medium voltage panels. If buyers select replacement units only by rated voltage or outer appearance, they risk mechanical fit failures or insufficient short-circuit withstand capacity. These defects introduce serious hazards on site.
Before confirming your order, double-check these items:
Final product selection must rely on valid technical specifications and test documentation.

Compatibility depends on your specific SM6 series, functional unit, mounting dimensions, operating interface, interlock layout and electrical ratings. Our team runs a full technical review before confirming fitment.
This product supports both 12kV and 24kV systems. Before ordering, make sure you confirm your selected configuration’s insulation level and short-circuit withstand characteristics.
Key parameters cover rated voltage, insulation level, rated short-time withstand current and duration, peak withstand current and short-circuit making capacity if needed. Required values are determined by your switchgear design and site fault level.
Supply original switchgear model, existing earthing switch specs, nameplate photos, mounting dimensions, operating interface details and available technical drawings.
You can request documentation for your selected configuration. Applicable ratings and standards should be cross-referenced against our manufacturer datasheets and supporting test records.
