Max. discharge current: 40 kA. Category IEC / EN / VDE: class I+II, II / type 1+2, 2 / B+C, C. Protection methods: (+)-PE, (-)-PE, (+)-(-). Protective elements: MOV. Enclosure: modular.
Technical info
Applications:
• For the protection of low-voltage devices against lightning strikes and surges,
• For installation according to the lightning protection zone (LPZ) concept in LPZ 0-1,
• Designed in accordance with the IEC 61643-31:2018 standard.
Features:
• Surge protection devices protect against lightning-induced surges in solar systems (photovoltaic power systems),
• These units must be installed in parallel in DC networks that need to be protected and provide both common and differential protection modes,
• Their location is recommended at both ends of the DC power line (on the solar panel side and the inverter/transformer side), especially if the line is external and long.
Series description:
• RSP-T...-DC.../... is an SPD of class I+II, II for low-voltage power systems,
• Primarily installed in the main distribution cabinet,
• The surge protectors are equipped with high-energy MOV (metal oxide varistors) with special thermal disconnectors and associated fault indicators.
