Reliable Operation of Photovoltaic Disconnect Switches
Photovoltaic disconnect switches provide a controlled means of isolating solar arrays, inverters and associated DC equipment from the electrical supply. A correctly selected operating handle enables the switch mechanism to be moved clearly and consistently between its operating positions.
The direct-mount design of the Mersen HDD250 is suited to applications where the disconnect switch is operated directly from the front of the mechanism. When correctly matched with a compatible Mersen MD100–250 switch, it provides a compact operating solution for photovoltaic and industrial DC installations.
Typical Applications
- Photovoltaic array isolation.
- Solar inverter systems.
- PV combiner and distribution panels.
- Industrial DC power systems.
- Renewable energy control equipment.
- OEM solar equipment assemblies.
- Replacement of compatible disconnect switch handles.
