Current-limiting fuses intended for medium voltage motors and motor controllers to protect against short circuit conditions. Include E-rated fuses for general purpose use, R-rated for backup applications and PT fuses for protection of potential transformers.
Mersen Ferraz Amp-Trap bolt-in Series fuses are used with 7.2 kV bolt-on mount motors. These R-rated backup fuses are UL-listed and have bolt-in mounting capability for direct connection to motor buses or terminals. They can be operated at temperatures as high as 80 degrees C and stored at temperatures as low as -25 degrees C. These fuses have mounting holes at the ends for easy installation.
Mersen Ferraz medium-voltage fuses are used to protect equipment and electrical circuits from overcurrent conditions and faults. They are ideal for power distribution networks, motor control centres, transformers and switchgear. These fuses have a glass-melamine laminate for arc flame resistance and provide electrical insulation performance in humid environments. They have copper with silver plating contacts for electrical conductivity. These fuses are further equipped with mounting-type clips for easy installation.
