Mersen 1B269.000000 Fusível NH2 160A gG 500V com Indicador Superior, Contacto de Lâmina, Caixa de Cerâmica

For industrial protection where reliability is non-negotiable, the Mersen 1B269.000000 NH2 fuse-link steps in with a 160 A rating and a 500 V AC ceiling. Unlike generic fuses that sacrifice precision for price, this gG-class unit is built to guard cables and conductors against both overloads and short-circuits, with a breaking capacity of 120 kA that keeps fault energy firmly in check.

Highlights

• NH2 size with blade contacts for secure, low-resistance mounting in standard fuse bases
• Top indicator gives immediate visual confirmation of a blown fuse, cutting downtime
• Ceramic body and silver-plated copper contacts endure harsh industrial environments
• Complies with IEC 60269-1 and VDE 0636-1, so it slots into existing installations without surprises
• Power dissipation of just 17.5 W at rated current means less heat and longer service life

In daily use

Installed in a distribution board or motor control center, this fuse-link behaves predictably: it carries 160 A continuously, tolerates normal inrush currents without nuisance tripping, and opens fast when a real fault occurs. The top indicator flips to red, so a technician can spot the failed fuse from across the room—no multimeter needed. The ceramic housing shrugs off temperature swings from -5°C to +40°C, and the silver-plated contacts resist oxidation, keeping resistance low over years of service.
