Frequently Asked Questions
What does the 'aR' characteristic mean for this fuse?
The 'aR' characteristic indicates that the fuse is a semiconductor protection fuse designed for partial range protection, providing fast-acting short-circuit protection while allowing for higher overload currents typical in semiconductor devices.
Can this fuse be used in DC applications?
While this fuse has a rated voltage of 250V DC, it is primarily intended for AC applications. Consult technical guidelines before using in DC circuits to ensure proper protection.
What is the significance of the clearing I2t and melting I2t values?
Clearing I2t represents the energy let-through during fuse operation, while melting I2t is the energy required to melt the fuse element. Lower values mean better protection for sensitive semiconductor devices.
How is this fuse mounted?
This fuse is designed for bolted mounting using L bracket terminals, ensuring a secure and reliable electrical connection.
