ABB GHR9010100R0002

Product introduction

The ABB GHR9010100R0002 is a high-performance power distribution fuse holder designed to provide reliable overcurrent protection in industrial electrical systems. As part of ABB’s extensive portfolio of low-voltage electrical components, the GHR9010100R0002 combines robust construction with precise engineering to safeguard critical equipment in demanding environments.

This 100A, 690VAC fuse holder is specifically engineered to accommodate NH00-size fuses, serving as a vital link between power distribution networks and industrial machinery. Its primary function is to house and protect fuses, enabling safe replacement during maintenance while ensuring rapid fault isolation during overcurrent events. Whether integrated into motor control centers, distribution panels, or machinery control cabinets, the GHR9010100R0002 ensures uninterrupted power flow under normal conditions and reliable protection when faults occur, making it indispensable in manufacturing plants, data centers, and infrastructure projects.

Core advantages and technical highlights

Industrial-grade durability: The ABB GHR9010100R0002 features a flame-retardant polyamide housing (UL94 V0 rated) that resists high temperatures and chemical exposure, ensuring longevity in harsh industrial environments. This material choice prevents ignition spread during electrical faults, enhancing overall system safety. The copper terminals with M8 screw connections provide low-resistance current paths, minimizing energy loss and heat generation—critical for maintaining efficiency in high-current applications like motor starters or heating systems.

Flexible installation options: With dual compatibility for 35mm DIN rail and panel mounting, the GHR9010100R0002 adapts to diverse cabinet layouts without compromising performance. This flexibility simplifies retrofits in existing systems and allows engineers to optimize space in new installations. The IP20 protection rating ensures compliance with safety standards by preventing accidental contact with live components, a essential feature in areas with frequent human interaction, such as factory floor control panels.

Reliable fault protection: The GHR9010100R0002 supports a 50kA short-circuit withstand capacity for 1 second, enabling it to endure the intense energy released during severe faults without structural failure. This capability ensures that the fuse holder itself does not become a hazard during catastrophic events, containing the fault to protect downstream equipment. Its precision-engineered fuse cavity maintains proper contact pressure, preventing arcing and ensuring consistent performance over thousands of operating cycles.

Typical application scenarios

In automotive manufacturing plants, the ABB GHR9010100R0002 is commonly installed in robotic cell control panels, protecting servo drives and motor controllers from overcurrents caused by mechanical jams or electrical faults. For example, in a welding robot station, the GHR9010100R0002 houses an NH00 fuse upstream of the robot’s power supply, isolating faults within milliseconds to prevent damage to expensive servo motors and control electronics. This rapid response minimizes downtime, as maintenance teams can quickly replace the fuse via the GHR9010100R0002‘s accessible design without disassembling critical components.

In renewable energy facilities, such as solar inverter stations, the GHR9010100R0002 safeguards DC-to-AC conversion systems. It is typically integrated into combiner boxes, where it protects inverter inputs from overcurrents caused by panel string mismatches or lightning-induced surges. The GHR9010100R0002‘s wide operating temperature range (-25°C to +70°C) ensures reliable performance in outdoor enclosures, even in extreme climates, making it ideal for desert or high-altitude solar farms.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing the ABB GHR9010100R0002, ensure the mounting surface (DIN rail or panel) is clean, flat, and capable of supporting the holder’s weight (including fuse). Use torque tools set to 5-6 Nm for terminal connections to ensure proper contact without damaging threads. Verify that the installation environment is free from condensation and corrosive gases, as these can degrade terminals over time. Disconnect all power sources and use lockout/tagout procedures to prevent accidental energization during installation.

Maintenance suggestions: Inspect the GHR9010100R0002 quarterly for signs of overheating (discoloration) or loose connections. Tighten terminals if necessary using the specified torque. When replacing fuses, use only NH00-size fuses with current ratings matching the circuit design—never substitute with higher-rated fuses, as this compromises protection. Clean dust from the housing using compressed air (max 5 bar) to maintain IP20 integrity. If the holder shows signs of damage (cracks, melted plastic), replace it immediately with a genuine GHR9010100R0002 to ensure continued safety.
