1.Core Product Positioning

Specialized DC-Side Overcurrent Protection for Photovoltaic and Energy Storage SystemsThe RDT8-PV PV DC fuse is specially designed for the DC side of photovoltaic power generation and energy storage systems, with full-range DC breaking capacity. As a key protective device, it effectively mitigates current fluctuations and short-circuit faults in PV and energy storage systems, prevents equipment burnout and arc ignition risks, and is applicable to DC-side overcurrent protection in centralized PV power stations, distributed PV systems and various energy storage facilities. It conforms to the industry development trend of high voltage and large power in the photovoltaic sector.

2.Core Structure and Material Configuration

Precision Manufacturing Ensures Stable Breaking PerformanceThe product consists of an isolator and a fuse link. The moving contact serves as a fuse tube carrier for the fuse link, featuring a compact structure and convenient assembly and disassembly, which is suitable for actual installation and maintenance in industrial scenarios.As the core component, the fuse link is manufactured with pure silver melt, high-quality quartz sand, high-strength fuse tube and cylindrical cap contacts. The application of high-grade raw materials guarantees the breaking performance and service life of the product, enabling rapid and reliable disconnection under overcurrent conditions to meet the safety protection requirements of PV and energy storage systems.

3.Product Models and Core Technical Parameters

Dual Specifications Cover Mainstream Voltages with Multi-Rating Precise MatchingThe RDT8-PV PV DC fuse in the New Leader Series is available in two core models, namely RDT8-32PV and RDT8-63PV, fully covering the mainstream DC voltage levels of 1000V and 1500V. The two models share a number of high-performance core indicators with differentiated adaptation to different application scenarios. The specific parameters are as follows:

✔️ Basic parameters: RDT8-32PV has a rated voltage of DC 1000V, rated current of 32A, and fuse link dimensions of 10×38mm; RDT8-63PV has a rated voltage of DC 1500V, rated current of 63A, and fuse link dimensions of 10×85mm.

✔️ General high-performance indicators: Both models have a peak withstand current and rated breaking capacity of 20kA, a minimum fusing current of 1.45In, protection class IP2X, and utilization category DC-PVO.

✔️ Current ratings: The fuse links of both models cover multiple current ratings ranging from 2A, 3A, 4A to 30A, enabling precise matching with PV and energy storage equipment circuits of different power levels.

4.Operating and Installation Specifications

Stringent Standards Adapt to Multi-Regional Operating ConditionsTo ensure stable operation of the product in various environments, clear specifications for normal operation and installation have been formulated for the RDT8-PV PV DC fuse. Meanwhile, special performance correction is made for high-altitude areas to adapt to PV and energy storage projects in different regions across the country:

⭕️ Ambient conditions: Ambient temperature ≤40℃, 24-hour average temperature ≤35℃, annual average temperature ≥-5℃; relative air humidity ≤50% at 40℃ and up to 90% at 20℃, with necessary condensation protection measures.

⭕️ Installation requirements: Install in positions free from obvious vibration and shock, applicable to pollution degree 3 and installation category III; mounted on TH35-7.5 standard rails by clip-on mounting and must be installed vertically.

⭕️ High-altitude current correction: Clear altitude current correction coefficients are defined, i.e., 1 for altitudes ≤2000m, 0.9 for 2000–3000m, and 0.8 for altitudes ≥3000m, avoiding performance attenuation caused by high-altitude environments.

5.Product Selection and Ordering Specifications

Clear Guidelines Guarantee Accurate Order Allocation and DeliveryPeople Electric has issued clear guidelines for the selection and ordering of the RDT8-PV PV DC fuse in the New Leader Series, facilitating customers to make accurate selections according to project requirements and ensuring efficient order allocation and delivery:
