FERRAZ SHAWMUT AJT20 Time-Delay Class J Fuse

The FERRAZ SHAWMUT AJT20 is a time-delay Class J fuse engineered for robust circuit protection. It incorporates a SmartSpot visual blown fuse indicator for easy identification and provides IEC Type 2 No Damage protection, safeguarding main, feeder, and branch circuits. The fuse's time-delay characteristics effectively handle motor and transformer inrush currents while delivering superior current-limiting performance. Its compact design reduces mounting space requirements, and the unique Class J dimensions prevent incorrect replacements. Applications include motor circuits, lighting, heating, transformers, control panels, and circuit breaker back-up.
