Why Choose the Lovato GA080D 3-Pole Photovoltaic DC Switch Disconnector?
The Lovato GA080D is a robust 3-pole direct-operating switch disconnector designed specifically for photovoltaic and industrial DC applications. Part of the Lovato GA series, it provides dependable manual isolation of DC circuits and is supplied complete with a black operating handle for straightforward installation and operation.
Designed for photovoltaic applications, the GA080D has an IEC conventional free-air thermal current rating of 80 A and supports DC-21B switching with poles connected in series according to the required system voltage. The switch can provide a DC-21B operational current of up to 32 A at 1000 V DC with the appropriate eight-pole series arrangement, making the platform suitable for high-voltage photovoltaic isolation duties.
The GA080D features a 1000 V rated insulation voltage, 8 kV rated impulse withstand voltage and a mechanical endurance of approximately 30,000 cycles. It can be mounted by screws to a plate or on a 35 mm DIN rail, while the operating mechanism can be padlocked in the OFF position without an additional accessory.

Reliable DC Isolation for Photovoltaic Systems
Photovoltaic switch disconnectors such as the Lovato GA080D provide a mechanical means of isolating DC circuits so that electrical equipment can be inspected, maintained or serviced. Because photovoltaic arrays can continue producing DC voltage whenever sufficient light is available, switching devices intended for these systems must be specifically designed to interrupt and isolate DC circuits.
The GA080D is engineered for photovoltaic applications and supports series connection of switching poles to achieve the required DC voltage and current performance. Its robust mechanical operating system, high insulation rating and padlockable OFF position make it suitable for PV distribution equipment, combiner systems and industrial DC installations requiring dependable manual isolation.
Typical Applications
- Solar photovoltaic DC installations.
- PV array and string isolation systems.
- Photovoltaic combiner and distribution equipment.
- Solar inverter DC isolation circuits.
- Industrial DC electrical systems.
- OEM renewable-energy and power distribution equipment.
