Frequently Asked Questions
What does the 'aR' speed/characteristic mean for this fuse?
The 'aR' characteristic indicates that this fuse is a partial-range semiconductor fuse designed to protect semiconductor devices by providing rapid interruption of short-circuit currents while allowing for inrush currents during normal operation.
Is this fuse suitable for DC applications?
While the fuse has a rated DC voltage of 300 V UL, it is primarily designed for AC applications at 250 V. Consult specific application requirements before using it in DC circuits.
How should this fuse be mounted?
This fuse-link is designed for bolted mounting using L bracket terminals, ensuring a secure and stable connection within fuse holders or panels.
What is the significance of the clearing I2t and melting I2t values?
Clearing I2t (100 A²s) indicates the energy let-through during fault clearing, while melting I2t (15.6 A²s) represents the energy required to melt the fuse element. These values are critical for coordinating protection and ensuring safe operation.
