Frequently Asked Questions
What does the time-delay characteristic mean for this fuse?
The time-delay characteristic allows the fuse to tolerate temporary current surges, such as motor start-up currents, without blowing. This prevents unnecessary downtime and fuse replacements.
Can this fuse be used for both AC and DC circuits?
Yes, the AJT20 is rated for use in both AC circuits up to 600 V and DC circuits up to 400 V, making it suitable for a variety of industrial applications.
How does the SmartSpot® indication system work?
SmartSpot® provides a visual indication by changing colour or appearance when the fuse has blown, allowing for quick and easy identification without testing equipment.
What is the breaking capacity of this fuse?
The fuse has a high interrupting rating of 200 kA, meaning it can safely interrupt fault currents up to this level without damage.
