What Are Low Voltage Switchgear Components?
Low voltage switchgear components are the building blocks of distribution panels – frames, busbars, breaker compartments, cable compartments, barriers and protection mounting – that panel builders assemble into complete boards.
Sourcing components from a switchgear factory ensures dimensional consistency, rated busbars and tested assemblies – reducing engineering and fit-up issues for panel builders.
- Frames & enclosures – fabricated panels and compartments.
- Busbar systems – rated copper busbars and connections.
- Sub-assemblies – breaker and metering compartments pre-built.
- 50,000m² factory – in-house sheet metal and fabrication.
- 350+ employees – engineering, quality and export teams.
- OEM / ODM & wholesale – custom branding, packaging and volume supply.
Main Types of Switchgear Components
We manufacture four component groups:
Panels & frames

Component Supply vs Complete Panel Purchase
Buying components gives panel builders flexibility and local assembly; buying complete panels transfers engineering and testing to the factory.
We support both models – the choice depends on your assembly capability and project volume.
