Description
The Mersen AJT2 is a time-delay 2A Class J fuse rated for 600V AC and 400V DC, designed to provide reliable current-limiting protection for main, feeder, and branch circuits across a wide range of loads. The Amp-Trap 2000® AJT fuse features time-delay characteristics that help handle typical motor and transformer inrush currents while providing superior current-limiting performance. Its compact Class J design requires significantly less mounting space than traditional 600V Class RK fuses, making it a practical choice for applications where panel space is limited.
Key Features
- 2A Time-Delay Protection: Provides time-delay overcurrent protection while accommodating typical motor and transformer inrush currents.
- 600V AC / 400V DC Rating: Suitable for electrical systems rated up to 600V AC and 400V DC.
- Class J Fuse: Provides current-limiting protection for main, feeder, branch, motor, transformer, and general-purpose circuits.
- High Interrupting Rating: Offers a maximum AC interrupting rating of 200 kA for applications with high available fault currents.
- Compact Design: Requires significantly less mounting space than 600V Class RK fuses, helping conserve valuable panel space.
- Ferrule Connection: Features a ferrule terminal design with tin-plated copper connection material and clip mounting.
- Open-Fuse Indication Options: The AJT series is available with either a non-indicating design or a SmartSpot visual open-fuse indicator.
