Zhejiang Hongman Electric Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of 800v pv low voltage fuse link in China. We are committed to providing high quality customized products made in China with competitive price. Welcome to wholesale bulk cheap 800v pv low voltage fuse link from our factory.
Product Introduction
The HMRS12 series HRC Fuse is matched exclusively for HMHR-400 three-phase fuse disconnectors, designed for 800V AC photovoltaic low-voltage power distribution circuits. This high-performance PV Low Voltage Fuse adopts thickened ceramic housing and precision pure copper melt, equipped with full-range overcurrent protection curve to deliver reliable overload & short-circuit isolation for PV combiner boxes and energy storage cabinets. As standard 800V PV Fuse, two size specifications (HMRS12C2:125–250A / HMRS12C3:300–400A) cover full current demands of medium & large solar power stations. The high-breaking HRC structure restricts intense fault arcs within the fuse body, eliminating fire risks under PV reverse surge current. Ultra-low temperature rise performance ensures long-term stable continuous operation inside compact three-phase switchgear.

FAQ
Q1: Can this HRC Fuse be directly matched with HMHR8 series three-phase disconnector?
A1: Yes. The HMRS12C2/C3 series PV Low Voltage Fuse is customized for HMHR8-400 disconnectors, all dimensional interfaces fully compatible without modification for 800V PV Fuse application.
Q2: What peak short-circuit current can this 800V PV Fuse withstand?
A2: Rated peak withstand current reaches 50kA. As standard HRC Fuse, it can safely cut extreme surge current from PV grid faults to avoid fire hazards inside distribution cabinets.
Q3: Does this PV Low Voltage Fuse need current derating for high altitude PV stations?
A3: Yes. Follow IEC altitude rule: derate 0.5% per 100m above 2000m to prevent overheating of the HRC Fuse under long-term operation.
