Mersen 63A NH00 Fuse Link

Description

The Mersen NH00GG50V63 is an industrial-grade, low-voltage high-rupturing-capacity (LV HRC) fuse link. It is designed to provide reliable overcurrent protection in electrical distribution systems, control panels, and other industrial applications. With a nominal current of 63A and a voltage rating of 500V AC, this fuse is suitable for a wide range of uses. The gG/gL characteristic ensures it is a general-purpose fuse, ideal for protecting cables and lines against both overload and short-circuit currents. This model includes a front indicator to easily identify a tripped fuse. Order now from PLC2Day for expert support and fast delivery.

FAQ

The 'gG' (formerly 'gL') designation indicates a general-purpose fuse characteristic according to IEC standards. It is designed to protect against both overload (slow-blow) and short-circuit (fast-acting) currents, making it suitable for protecting cables, lines, and general equipment.

No, the gG/gL characteristic is not fast enough for protecting sensitive semiconductor devices like thyristors, IGBTs, or diodes. For those applications, you should use a high-speed fuse with an 'aR' or 'gR' characteristic.

Yes, this NH00 size fuse is designed with insulated gripping lugs. It can be safely installed and removed using a standard NH fuse handle or puller designed for live-line work, ensuring operator safety.
