The FERRAZ SHAWMUT AJT series fuses offer a combination of protection and visual indication. Featuring a solid-state SmartSpot visual blown fuse indicator, these fuses provide instant confirmation of a tripped condition. Their time-delay characteristics are ideal for handling motor starting and transformer inrush currents while providing superior current-limiting ability. Recommended for arc flash energy reduction, the AJT fuses also require less mounting space than traditional Class RK fuses, making them suitable for a wide range of applications including motor circuits, branch circuits, and circuit breaker back-up.
