What This Range Is For
Dis-connector circuit breakers for isolation and protection in low-voltage distribution boards and control panels. The HTH2-125 series provides a mechanical disconnection function with overcurrent protection, suitable for industrial, commercial and building applications where manual isolation is required.
Who Buys This Range
- Electrical wholesalers stocking isolation and protection devices for distribution boards
- Panel builders and switchgear assemblers integrating protection and isolation in control cabinets
- Industrial machine builders needing safe isolation in control panels
- Commercial and building contractors installing final circuit protection with visible disconnection
Problems It Solves
- Final circuits need a manual disconnection point that is clearly visible and mechanically secure
- Standard circuit breakers do not provide a visible disconnection gap for safety during maintenance
- Installers require a device that combines isolation and protection in one DIN-rail mounted unit
- Panel builders need a consistent footprint for both protection and isolation functions without extra space
Where It Is Used
- Main distribution board isolation in commercial buildings and offices
- Control panels in industrial machinery requiring safe manual disconnection
- Sub-main distribution in electrical panels where both protection and isolation are needed
- Maintenance access points in switchgear assemblies where visual confirmation of isolation is required
Advantages
What Separates This Range
- Mechanical disconnection with visible break in the circuit for safety during maintenance
- Built on a standard DIN-rail footprint compatible with MCB and other low-voltage devices
- Combines overcurrent protection and isolation in a single unit, reducing panel space
- Rated for 125A, suitable for main and sub-main distribution circuits
- Same factory produces conventional and smart versions of related devices, enabling future upgrade paths
