Frequently Asked Questions
What is the difference between a time-delay fuse and a fast-acting fuse?
A time-delay fuse, like the A4BQ2000, allows temporary overloads without blowing, which is ideal for motors and transformers. Fast-acting fuses blow quickly to protect sensitive electronics from short circuits.
Can this fuse be used in both AC and DC circuits?
Yes, the A4BQ2000 is rated for both 600VAC and 500VDC, making it suitable for dual-voltage applications.
What type of mounting does this fuse require?
This fuse is designed for bolted mounting with blade terminals to ensure a secure connection.
What is the breaking capacity of this fuse?
The fuse has a maximum interrupting rating of 200 kA AC, providing high fault clearing capability.
