OFAFC1GG200

The ABB OFAFC1GG200 is a high‑rupturing‑capacity (HRC) DIN‑type fuse link designed for overcurrent protection in low‑voltage electrical distribution systems. It is part of ABB’s OFAFC family of gG‑characteristic fuse links, used to protect power circuits, feeders, motors, and control equipment from overloads and short circuits. This compact fuse link fits into compatible DIN fuse holders or switch‑fuse disconnectors to provide reliable fault interruption.

Parameters Nominal Fuse Current: 200 A — protects circuits with continuous current up to this value before blowing. Utilization Category: gG — general purpose protection for overload and short circuit in power distribution. Rated Operational Voltage: Up to 690 V AC for three‑phase networks or 500 V AC in some configurations. Breaking Capacity: High fault current interruption capability suited to industrial electrical installations. Standards: Designed to meet relevant international low‑voltage fuse standards for HRC protection. Mechanical & Physical Fuse Size: DIN‑type HRC link with compact rectangular profile for modular assemblies. Construction: Metal and ceramic/fuse element housing engineered for safe, high‑energy fault interruption. Replacement: Plug‑out/plug‑in style fuse link for easy maintenance and replacement within compatible holders. Environmental & Operational Operating Environment: Suitable for installation inside electrical enclosures, distribution boards, motor control centers, and switchgear. Ambient Conditions: Designed to operate over typical industrial ambient temperature ranges. Installation: Used with appropriate DIN‑type fuse holders or switch‑fuse disconnect devices for secure, code‑compliant installations. Typical Applications Primary overload and short‑circuit protection in low‑voltage power distribution networks. Protection of motors, transformers, and feeders in industrial control panels. Overcurrent protection in switchboards, motor control centers (MCC), and distribution panels. Integration with fusible disconnect switches to provide combined isolation and protection.
