As a dedicated manufacturer of electrical protection components, Jinhua Dika Electrical Equipment Co., Ltd. is proud to introduce the FKPV-32-2 DC Solar Fuse. Engineered specifically for the demanding conditions of photovoltaic (PV) systems, this 32A fuse is a critical safeguard for your DC circuits. Our commitment to quality, backed by a comprehensive Mill Test Report (MTR) for traceability and verification, ensures you receive a reliable component that protects your investment in solar energy infrastructure. With over a decade of experience supplying global markets from North America to Southeast Asia, we understand the stringent requirements for safety and performance in renewable energy applications.
The FKPV-32-2 fuse is designed to interrupt fault currents in DC solar arrays effectively, preventing damage to inverters, charge controllers, and wiring. Its construction and performance are tailored for the unique challenges of DC arc suppression. Let's delve into the key features and technical specifications that make this fuse a preferred choice for system integrators and installers.
- Precision Engineering for DC Applications: Unlike standard AC fuses, the FKPV-32-2 is specifically designed to extinguish DC arcs, which are more difficult to quench due to the absence of a natural current zero point.
- High-Purity Materials: Utilizes silver alloy elements and robust ceramic bodies to ensure stable performance, low resistance, and excellent thermal characteristics under high DC voltage stress.
- Enhanced Safety: Provides reliable overcurrent protection, isolating faulty strings to prevent fire hazards and protect expensive downstream equipment like inverters.
- Compliance-Oriented Design: Manufactured in a facility adhering to stringent quality management systems, ensuring consistent production standards.
- Full Traceability: Each batch is supported by a Mill Test Report, offering documented proof of material composition and electrical performance tests.
The technical parameters of the FKPV-32-2 fuse are critical for proper system design and compatibility.
| Parameter | Specification |
|---|---|
| Rated Current (In) | 32 A DC |
| Rated Voltage (Un) | 1000 V DC |
| Fuse Type / Model | FKPV-32-2 |
| Breaking Capacity | Designed for high DC fault currents |
| Operating Temperature Range | -40°C to +85°C (typical for PV environments) |

Choosing the FKPV-32-2 DC Solar Fuse provides tangible benefits for your projects:
- System Reliability: Minimizes downtime by accurately disconnecting only the faulted circuit, allowing the rest of the PV array to continue generating power.
- Cost-Effective Protection: Acts as a sacrificial device, protecting significantly more expensive components like central or string inverters from catastrophic failure.
- Simplified Compliance: Using a purpose-built DC fuse aids in meeting electrical safety codes and standards for solar installations.
- Supply Chain Confidence: Sourcing from an established manufacturer with an annual export value of US$1-1.5 million and a global reach ensures stable supply and professional support.

Frequently Asked Questions (FAQ)
Q1: What is the main purpose of the FKPV-32-2 fuse in a solar system?
A: Its primary role is to provide overcurrent protection for DC branches within a photovoltaic array. It safely interrupts excessive current caused by faults like short circuits or ground faults, protecting wiring, combiners, and inverters.
Q2: Can I use a standard AC fuse of the same amperage instead of this DC solar fuse?
A: It is strongly discouraged. DC circuits present a different arc-quenching challenge. A DC-specific fuse like the FKPV-32-2 is engineered to safely extinguish a DC arc, which an AC fuse may not accomplish, posing a significant fire risk.
Q3: What does the "Mill Test Report" (MTR) provide?
A: The MTR is a certificate from the manufacturer detailing the raw materials used (e.g., silver content), the results of factory electrical tests (like resistance, time-current characteristics), and batch traceability. It verifies the product meets its stated specifications.
Q4: What is the maximum system voltage this 32A fuse can handle?
A: The FKPV-32-2 is rated for DC voltages up to 1000V. It is suitable for many commercial and utility-scale PV systems operating at common string voltages.
Q5: How do I select the right amperage for my solar string?
A: The fuse rating should be slightly higher than the maximum possible current of the protected string (considering Imp and safety factors like 1.56 per NEC), but lower than the current-carrying capacity of the cable. Professional design is recommended.
Q6: Are these fuses certified to specific international standards?
A: While our manufacturing processes follow rigorous quality systems, specific certifications for the product (like UL or TUV) are available upon request. Please contact us for the latest certification status for your target market.
Q7: What is the typical lead time for orders?
A: Lead times can vary based on order quantity and current production schedule. As an experienced exporter, we leverage ports like Shanghai and Ningbo for efficient shipping and can provide estimated timelines upon inquiry.
Q8: Do you offer other amperage ratings for PV DC fuses?
A: Yes, we typically offer a range of DC fuse ratings to cover various system requirements. Please inquire about other available models similar to the FKPV series.
