Product Introduction
HongMan HMHR1 series fuse type isolation switch includes multi-pole specifications of 1P/2P/4P, compatible with AC690V, AC800V, AC1000V, AC1140V AC power distribution systems, and matched with special HMRS12C1 fuse links. It is a dedicated disconnecting and isolating component for photovoltaic inverters, low-voltage distribution cabinets and industrial & commercial power distribution circuits. Adopting integrated insulating housing with built-in arc-extinguishing structure, it delivers stable breaking and isolation performance. As a universal 800V Solar fuse holder, it fits photovoltaic AC & DC complete equipment, equipped with modular structure of standard 1P HRC FUSE Holder, which supports free combination of single-pole, two-pole and four-pole to meet multi-circuit power distribution demands. It can also be extended to form complete power distribution schemes with 3P fuse holder, widely applied to solar PV power stations, industrial control distribution boxes and general low-voltage power circuits.

Product Advantage
1.Modular multi-pole combined design for diversified power distribution scenarios Standard 1P/2P/4P housings are available. The single-pole independent unit is mature 1P HRC FUSE Holder, which can be freely spliced to form three-phase complete distribution with 3P fuse holder. It can be flexibly matched for residential PV and industrial power cabinets, with full range of dedicated specifications for 800V Solar fuse holder PV systems.
2.Wide voltage full coverage, compatible with high & low voltage AC PV systems Supports full voltage grades from AC400V to AC800V, perfectly matching 800V PV AC side. It provides stable isolation under high voltage conditions, only allowing no-load opening to avoid fuse damage caused by load operation.
3.Full range of current ratings for zero blind spot selection Complete current grades from 0.5A to 400A cover small-power control circuits and high-power power circuits. Matched with special HMRS12C1 fuse links, it delivers dual protection against overload and short circuit with high protection precision.
4.Weather-resistant design for stable operation under extreme temperature & altitude Operating temperature ranges from -40℃ to +60℃ without current derating below 2000m altitude; accurate current derating calculation formula is provided for altitude over 2000m. It withstands Class 3 pollution environment with dustproof and moisture-proof performance, enabling long-term stable operation in outdoor PV power stations and humid workshops.
5.Integrated flame-retardant insulating housing for upgraded safety protection One-piece molded flame-retardant shell with closed built-in arc extinguishing chamber ensures no arc flash during short-circuit breaking. Insulation clearance meets high-voltage system standards to prevent electric leakage and housing breakdown, complying with safety standards of high-voltage 800V Solar fuse holder.
Production Process & Quality Control System
Ceramic Shell Forming The ceramic body is formed through high-temperature sintering to deliver reliable insulation and explosion-proof performance.
Copper Contact Machining Integrally stamped thickened solid copper blades are electroplated with copper-tin alloy for anti-oxidation, effectively reducing contact resistance.
Fuse Element Assembly Precision fuse strips are fitted with high-purity quartz sand (99% silicon content) to achieve rapid arc extinction.
Finished Product Testing Every single unit undergoes individual testing for breaking capacity, temperature rise and overload fusing performance.
Aging Sampling Inspection Long-term operation under rated current is simulated to eliminate potential overheating risks.
Full-process traceable quality control ensures consistent performance of every fuse link.

FAQ
Q1: What are the core application scenarios of this HRC 1P 800V PV Fuse holder?
A1: The HRC 1P 800V PV Fuse holder is a single-pole HRC high-breaking fuse base specially customized for 800V AC photovoltaic systems. It is widely used in rooftop distributed PV AC combiner boxes, small commercial inverter AC cabinets, new energy vehicle auxiliary power distribution boxes and light industrial 800V low-voltage power distribution equipment, providing independent overcurrent and short-circuit protection for single solar AC branches.
Q2: What breaking capacity can this HRC 1P 800V PV Fuse holder support to guarantee PV system safety?
A2: Matched with standard gG HRC solar fuse links, the HRC 1P 800V PV Fuse holder reaches a rated breaking capacity of 120kA@AC500V and 50kA@AC690V, and can stably operate under a maximum working voltage of AC800V. The HRC high arc extinguishing structure can quickly cut off fault current and isolate high-energy AC arcs to prevent cabinet fire hazards caused by PV short-circuit faults.
Q3: What international certifications and test reports can you provide for bulk tender and customs clearance?
A3: Each batch of HRC 1P 800V PV Fuse holder is attached with complete CE, RoHS, ISO9001 and IEC60269-2 official test reports. All certification documents support overseas PV project bidding, third-party factory audits and cross-border customs clearance without additional certification fees for buyers.
