Frequently Asked Questions
What does the time-delay feature mean for this fuse?
The time-delay characteristic allows the fuse to withstand temporary current surges, such as motor start-up currents, without blowing, providing protection against sustained overloads and short circuits.
How does the SmartSpot® indication system work?
The SmartSpot® system provides a visual indication when the fuse has blown, making it easy to identify and replace without additional testing equipment.
Is this fuse suitable for DC applications?
Yes, the AJT40 fuse is rated for use up to 400 VDC, making it suitable for both AC and DC circuits within its voltage and current ratings.
What is the significance of the Class J rating?
Class J fuses have a high interrupting rating and are designed for industrial applications requiring compact size and superior protection, especially in motor circuits.
