ETP External Transformer Protection Fuses

The Sure Guard ETP back-up current-limiting fuses are designed to protect overhead distribution systems and are used in series with another protective device (such as an expulsion fuse). This combination limits the high-fault current to a safe level, thus providing protection through the complete range.

Medium Voltage Fuses

Current-limiting power fuses are widely used in industrial plants, shopping centers, hospitals, schools, office buildings and underground residential service because they afford excellent over-current protection and noiseless operation, and because they can be used in confined spaces.

AJT - Class J - Time-delay

Amp-Trap 2000® AJT fuses provide non-indication as well as a SmartSpot visual open fuse indicator. With advanced material technology the AJT fuse provides IEC Type 2 No Damage protection to main, feeder, and branch circuits, for all types of loads — yet, they require only half the mounting space needed for 600VAC Class RK fuses. AJT’s time-delay characteristics are ideal for handling typical motor and transformer inrush currents, while also providing superior current-limiting ability.
