TR3R - 3 Amp Fuse

TR3R - 3 Amp Fuse

The TR3R is a 3 Amp Class R time-delay cartridge fuse made for your applications that need dependable overcurrent protection without nuisance openings during normal equipment startup. Its time-delay design allows temporary inrush current to pass while still responding to overloads and short circuits that could damage electrical equipment. With a 200 kA interrupting rating at 250V AC, the TR3R is suitable for electrical systems where high available fault current is a consideration. Its current-limiting Class R construction helps you reduce the energy released during a fault, providing another layer of protection for connected equipment. The compact non-indicating cartridge design also makes it an easy replacement in compatible Class R fuse holders and disconnect switches. From motor control panels and HVAC systems to industrial machinery and transformers, the TR3R is a practical choice for keeping your electrical equipment protected and operating as intended.
