Why Choose the Lovato SG2DG600M2 Type 2 DC Surge Protection Device?
The Lovato SG2DG600M2 is a compact and reliable Type 2 DC surge protection device (SPD) specifically designed to protect photovoltaic installations against transient overvoltages caused by indirect lightning effects and induced electrical surges. As part of the Lovato Electric SG2DG series, it provides dedicated protection for the DC side of solar PV systems using replaceable plug-in cartridges for straightforward maintenance.
Designed for +, -, PE photovoltaic circuits, the SG2DG600M2 provides a rated discharge current In of 20 kA and a maximum discharge current Imax of 30 kA with an 8/20 µs waveform. Its voltage protection level Up of less than 1.9 kV helps limit potentially damaging transient voltages reaching photovoltaic inverters and other connected DC equipment.
With a rated operational voltage and maximum continuous operating voltage Ucpv of 600 V DC, the SG2DG600M2 is purpose-built for photovoltaic DC power lines. Integrated thermal protection, frontal operating/end-of-life indication and a compact two-module DIN rail format provide dependable protection while simplifying installation and maintenance within PV distribution and combiner enclosures.

Reliable Surge Protection for Photovoltaic DC Systems
Type 2 photovoltaic surge protection devices such as the Lovato SG2DG600M2 divert transient surge currents away from sensitive DC equipment while limiting the voltage appearing across the protected installation. This helps protect photovoltaic inverters, DC distribution equipment and other connected components against transient overvoltages associated with indirect lightning and induced surge events.
The SG2DG series is specifically designed for installation on the DC side of photovoltaic systems. Its replaceable cartridges allow individual surge protection elements to be renewed when required, while integrated thermal protection and frontal status indication make it easy to identify the operating condition of the device during routine inspection and maintenance.
Typical Applications
- Solar photovoltaic DC installations.
- PV string and array protection.
- Photovoltaic combiner and distribution boxes.
- DC-side protection for solar inverters.
- Commercial and industrial photovoltaic systems.
- Residential solar PV installations.
- PV systems requiring Type 2 transient overvoltage protection up to 600 V DC.
