Frequently Asked Questions

What does "quick acting" mean for this fuse?

"Quick acting" means the fuse responds rapidly to overcurrent conditions, providing fast protection to prevent damage to sensitive components.

Is this fuse suitable for DC applications?

No, this fuse is rated for AC use only, as specified under the AC or DC technical specification.

Can I use this fuse in a circuit with a voltage higher than 250V AC?

No, the fuse is rated for a maximum of 250 V AC. Using it above this voltage may compromise safety and performance.

What is the significance of the melting I2t value?

The melting I2t value (410 A²s) indicates the energy let-through by the fuse during fault conditions, important for coordinating protection with other devices.
