Switchgear & distribution
Medium-voltage switching and low-voltage distribution for your electrical and protection requirements.
MVSwitching & feeder arrangements
LVDistribution assemblies
Defined interfacesProtection, controls & metering
THE EQUIPMENT FAMILY
A clear interface at every stage.
Start with the single-line diagram, prospective fault duty and operating requirements. We align these with manufacturer documentation and supply boundaries.
Low-voltage distribution
Incoming and outgoing assemblies selected for the load, fault duty and operating requirements.
Package interfaces
Coordinate switchgear with transformers, prefabricated substations and storage conversion equipment.
TECHNICAL CONSIDERATIONS
Select on the right basis.
Confirm ratings, compliance evidence and availability for the selected model.
REPRESENTATIVE SELECTION DATA
KYN28-12 metal-clad switchgear
| Parameter | Family / selection basis | Project consideration |
|---|---|---|
| Rated voltage | 3 / 6 / 7.2 / 12 kV | 50 Hz series; selected configuration to match the network. |
| Rated current | 630–4,000 A | Rating depends on the selected assembly. |
| Short-time withstand | 16–50 kA for 4 seconds | Confirm the tested voltage, current and fault-duty combination. |
Representative manufacturer series data, reviewed August 2026. Select ratings together; the published range does not establish site acceptance or internal-arc classification.

| Parameter | Family / selection basis | Project consideration |
|---|---|---|
| System rating | Voltage, frequency and continuous current | Select around the project single-line diagram and operating duty. |
| Fault duty | Prospective fault level and required withstand | Verify the exact assembly and device configuration. |
| Protection | Breaker/fuse selection, relays and coordination | Protection studies and settings have a defined engineering responsibility. |
| Operation & access | Interlocking, isolation and maintenance requirements | Confirm the operating sequence and site access philosophy. |
| Controls & metering | Signals, communication and interface requirements | Agree the point list, protocols and responsibility for integration. |
| Evidence | Selected assembly’s test and documentation basis | Do not infer an internal-arc classification or approval from another configuration. |
APPLICATIONS

COMMON QUESTIONSBefore you
Before you
specify.
Are internal-arc ratings standard across the range?
No. Check the exact tested assembly, installation arrangement and required classification.
Does this include rack PDUs and busway?
This offer covers MV switchgear and LV distribution. Rack PDUs and busway are shown as system context; supply requires separate qualification.
Who defines protection settings?
The project engineer and equipment suppliers agree responsibility. Switchgear supply does not include a complete site protection study unless expressly agreed.
