Why Choose the Mersen Z076474 High-Voltage Motor Protection Fuse?
The Mersen Z076474, catalogue reference 45ASB36V160P-1, is a high-voltage DIN back-up fuse-link specifically designed to protect medium-voltage motors against the effects of short-circuit currents while withstanding repeated motor starting currents. Part of the proven Mersen Limitor® aSJB/D series, it provides dependable motor protection for industrial switchgear and motor control systems.
Rated at 3.6 kV AC and 160 A, the Z076474 delivers rapid current-limiting protection, interrupting fault currents before they reach their maximum prospective peak. This helps minimise thermal, electrical and mechanical stress on motors, cables and associated switchgear while maintaining reliable motor operation.
Manufactured using pure silver fuse elements, silver-plated brass end caps and a melamine fibreglass body, the fuse measures 67 mm in diameter and 192 mm in length. It incorporates an integrated 20 N striker for operation of compatible switchgear or indication following fuse operation.
