SUNTREE-DC Surge Protector 3pole 1000VDC 20kA – 40kA

Investing in the SUNTREE 3-Pole 1000VDC Surge Protector is critical for safeguarding high-performance solar installations against transient overvoltages. This device is specifically engineered to dissipate heat quickly, reducing the service temperature and extending the operational life of the unit. A key safety innovation is the inclusion of a flash barrier, which prevents arc propagation during intense current impacts. The unit utilizes a green and red visual indicator system: green confirms the module is healthy, while red signals that the protection has been exhausted and requires replacement. For advanced monitoring, it supports optional remote contact signaling through a floating changeover contact. To ensure maximum safety, the design incorporates a combined disconnection and short-circuiting device with safe electrical isolation, preventing fire damage caused by DC arcs. When installing, it is recommended to maintain a minimum 10mm safety distance from other grounded parts using suitable electrical insulators. This SPD is compliant with international standards, offering a reliable defense for the DC side of your system. Its plug-in module design allows for rapid maintenance without needing to rewire the entire base. By diverting surge currents safely to the ground, this 3-pole protector ensures that the most expensive components of your solar infrastructure, such as high-voltage string inverters, are protected from atmospheric discharges and grid-related electrical spikes.
