DC Fuse Holder | 1000V High-Performance & IP65 Rated

Our DC fuse holders are engineered with high-grade glass-filled nylon and phenolic materials that exhibit exceptional thermal stability, maintaining structural integrity even at sustained elevated temperatures. In practical terms, the holders can operate continuously at 125°C without deformation or loss of electrical performance, thanks to our unique heat dissipation design featuring venting channels and increased surface area. This thermal resistance is crucial in applications such as solar power plants where sun exposure can push enclosure temperatures to 80°C or more. Real-world data from our installation in a Middle Eastern PV plant shows that our holders maintained a case temperature 15°C lower than competitor products.

Reliability in DC fuse holders is not just about electrical performance; the mechanical design ensures secure fuse seating and stable contact pressure over thousands of cycles. Our holders feature a patented spring-clip mechanism that delivers a constant contact force of 15N, preventing loosening due to vibration or thermal cycling. This design has undergone 50,000 insertion and withdrawal cycles in our testing lab, equivalent to 20 years of field use. The housing is made of UV-resistant polyamide, which withstands prolonged sun exposure without becoming brittle or discolored, preserving its structural strength. In a case study with an Australian mine site, our holders were subjected to extreme dusty.
