ABB OFAF000H40 1SCA022627R1120 HRC Fuse Link NH000 40A gG

The ABB OFAF000H40 (article 1SCA022627R1120) is an HRC fuse link in NH000 size, designed to protect electrical circuits against overloads and short-circuit faults. Rated at 40 A and suitable for voltages up to 500 V AC or 250 V DC, it delivers high-capacity fault interruption in both AC and DC distribution systems.

Technical specifications:

• Series: OFAF000H40
• ABB article number: 1SCA022627R1120
• EAN: 6417019205540
• Rated current: 40 A
• Size: NH000
• Rated voltage: 500 V AC / 250 V DC
• Utilization category: gG
• Rated breaking capacity: 120 kA (AC) / 80 kA (DC)

Features and benefits:

• NH000 form factor fits standard NH fuse bases and holders, making installation and field replacement straightforward
• gG utilization category covers full-range protection - both overload conditions and short-circuit currents - on general-purpose AC circuits
• Breaking capacity of 120 kA (AC) handles severe prospective fault currents, making it suitable for high-power distribution environments
• Dual-voltage rating of 500 V AC and 250 V DC permits use across a broad range of AC and DC system architectures

Applications:

• Cable and line protection in AC distribution boards and panels operating up to 500 V
• Short-circuit protection in industrial and commercial switchgear assemblies
• DC circuit protection in battery-backed power systems and similar 250 V DC installations
• General-purpose circuit protection in building services and industrial electrical installations
