Overview

The Mersen A229747 is a high-quality NH Standard fuse-link, specifically a gG type, designed for robust protection in industrial electrical systems. This NH1 size fuse-link operates at a rated voltage of 690VAC and 400VDC, with a current rating of 63A. It features isolated gripping lugs for enhanced safety during handling and a double indicator system to clearly signal its status. The body width is 30 mm, consistent with the NH1 standard. As part of the Mersen NH plug-in fuse system, this fuse-link is crucial for protecting cables and equipment from overcurrents and short circuits. The gG classification signifies a full-range breaking capacity, meaning it can interrupt any current surge from the lowest fusing current up to its maximum breaking capacity. This makes it suitable for use as sole protection for electrical devices and industrial setups, effectively mitigating the electrodynamic effects of very high short-circuit currents. Key specifications include: - SKU: A229747 - Manufacturer: Mersen - Type: NH Standard fuse-link - Class: gG - Size: NH1 - Rated Voltage AC (IEC): 690V - Rated Voltage DC (IEC): 400V - Rated Current (In): 63A - Body Width: 30 mm - Indicator Type: Double Indicator - Contact Type: Isolated Tags - Power Dissipation at In: 6.6 W (from catalog data for similar NH1GG50V63-1) - Package Weight: 0.28 kg (from catalog data for similar NH1GG50V63-1) Due to the design of the NH system, which cannot guarantee non-interchangeability of rated current, handling and replacement of these fuse-links must be performed by a qualified professional. This Mersen fuse-link ensures reliable and safe operation for critical electrical infrastructure.
