More Info
The SMA DC_SPD_KIT6-10 surge protection kit features the Raycap ProTec SPD designed specifically for photovoltaic systems to guard against transient overvoltages.
Its Class II / Type 2 rating and UL 1449 4th Edition certification ensure compliance with stringent safety and performance standards.
The device mounts easily on a 35 mm DIN rail, making it ideal for integration within string boxes and inverter DC input panels.
A thermoplastic housing rated UL 94 V-0 provides fire resistance, while the IP20 enclosure protects internal components.
Models are available with optional remote contacts to enable alarm and system monitoring capabilities.
The built-in thermal disconnect and green flag LED indicator provide real-time operational status and enhance safety by disconnecting during fault conditions.
Designed to operate reliably in harsh environments, it supports altitudes up to 13,123 ft (4000 m) and temperatures from –40°F to 158°F.
With a high short-circuit current rating of 50 kA, the SPD withstands severe fault currents common in solar installations.
SMA is a global leader in solar inverter technology, delivering innovative and reliable solutions for residential, commercial, and utility-scale solar energy systems.
