Fast-acting fuse combines two highly desirable features such as high current limitation and a small physical size. These fuses have glass melamine body construction for superior dimensional stability and catalog numbers stamped into the blades for permanent recognition. It finds wide range of application in circuit breakers, load centers, metering centers, panel boards and switchboards. Their unique dimensions inhibit the exchange of other fuses with lower voltage ratings or current limiting capability. It has an interrupt current rating of 200 kilo-Amps at 300 VAC and 50 kilo-Amps at 160 VAC. Class T fuse is UL listed, DC tested, CSA certified and meets RoHS compliant standards.
