Eaton British Standard Fuse For Red Spot Series Fuse Holders, T Speed, 80kA Breaking Capacity - NIT20
Need a 'weak-link' fuse to prevent overcurrent and short-circuit faults? Try this British Standard fuse from Eaton. As it's a material-dependent unit, the wire inside melts when supplied with excess heat, current or voltage. This safely breaks your circuit to keep you and your equipment protected and also means you're not reliant on digital processes. Slotted metal tags let you choose between using it as an offset tag or a centre tag component, so you can adapt it to suit your needs. An IEC 60269-2 approval certifies it's a viable option for your low-voltage applications as it's been tested for safety. This fuse is commonly used in a wide variety of industrial applications, electrical equipment and wiring systems.
Features & Benefits
• High-rupture capacity fuse prevents downtime through false trips
• High breaking capacity of 80kA, so stops even significant surges of current from harming you and your equipment
• Works with AC and DC voltages for versatility
• High breaking capacity of 80kA, so stops even significant surges of current from harming you and your equipment
• Works with AC and DC voltages for versatility
Will this fuse work in high-density mounting applications?
Yes. This fuse's low temperature rise and slow-acting burn characteristics make it safe to use for high-density mounting as it won't generate dangerous levels of heat or contribute to the spread of flames in case of a fire.
