Mersen 1B275.000000 NH2 250A gG 500V NH poistková vložka s horným indikátorom

For industrial power distribution, the Mersen 1B275.000000 NH2 fuse-link stands out by combining a 250 A rating with a full-range gG operating class, ensuring reliable protection for cables and lines under both overload and short-circuit conditions. Its ceramic body and silver-plated copper contacts provide robust performance in demanding environments, while the top indicator gives clear visual confirmation of fuse status. Ideal for low-voltage networks up to 500 V AC, this fuse-link is a dependable choice for maintaining system integrity.

Highlights

• Rated current 250 A, rated voltage 500 V AC, suitable for industrial applications.
• Operating class gG (general purpose) for full-range protection of cables and lines.
• High breaking capacity of 120 kA at 500 V AC for effective short-circuit interruption.
• Top indicator for quick visual identification of blown fuse.
• Blade contact design for secure mounting in NH2 fuse bases.
• Compliant with IEC 60269-2 and VDE 0636-2 standards.

In daily use

In practice, this NH2 fuse-link installs easily into standard fuse bases, and its top indicator allows maintenance personnel to quickly spot a tripped fuse without removing it. The low power dissipation of 22 W at rated current helps minimize energy losses, contributing to efficient operation. Its robust ceramic body withstands mechanical and thermal stresses, making it suitable for continuous duty in power distribution panels and industrial machinery.
