Description
422 Series fuse is a 250 V rated Wire-in-Air Surface Mount Fuse,
designed specifically to provide circuit protection to space
constrained application. The wire-in-air design of the 422 Series
results in a relatively high I2t in a 2410 size.

Notes
1. AC Interrupting Rating tested at rated voltage with unity power factor. DC Interrupting Rating tested with time constant <0.8 ms for 32 VDC, <2.2 ms for 86 VDC, <0.22 ms for 125 VDC, and <0.1 ms for 250 VDC.
2. Nominal Resistance measured with <10% rated current.
3. Nominal Melting I2t measured at 1 msec. opening time.
4. Interrupting Rating may differ based on Agency Approval. See Agency Approval certificate for more details.
