Product: DC Surge Protector protection, Model RND1C, Type Surge arrester, Size 2 Overview The RND1C DC surge protector is a compact surge arrester designed for DC systems up to 500V. It delivers reliable transient protection with a nominal discharge current of 20KA and a maximum discharge current of 40KA. This unit is a nonsmart, device intended to guard sensitive DC equipment from voltage spikes. Key benefits Effective surge suppression: Rated nominal discharge current 20KA and max discharge current 40KA to absorb and divert energy transients before they reach connected equipment. Designed for DC systems: Input voltage 500V compatibility makes it suitable for a wide range of DC power installations. Simple and reliable: Not a smart device, providing straightforward passive protection without software or network requirements. : is_customized Yes indicates configuration options to fit installation needs. Low chemical concern: Hignconcerned Chemical None assures no concern chemicals are specified for the product. Features and performance Model: RND1C, Type: Surge arrester Size: 2, compact form factor for easy integration into panels and equipment racks Electrical ratings: Nominal Discharge Current 20KA, Max Discharge Current 40KA, Input Voltage 500V Function: Diverts surge energy away from connected loads, reducing the risk of damage to DCpowered devices Installation: Intended for installation in DC distribution lines, combiner boxes, or equipment enclosures requiring surge protection Practical applications and scenarios Solar photovoltaic arrays: Protect inverters, charge controllers, and combiner boxes from lightninginduced or switching transients on 500V DC strings. Battery energy storage and DC distribution: Provide surge protection for battery systems, DC busbars, and industrial control equipment. Telecom and industrial equipment: Shield DCpowered telecom cabinets and control panels from transient overvoltages on supply lines. Why choose this product The RND1C offers clear, applicationfocused protection for DC systems where a robust nominal discharge rating and a higher maximum discharge capacity are required. Its compact Size 2 form and configurable options make it practical for retrofit or installations that need reliable surge arresting without added complexity.
