DESCRIPTION

The 322010 is a lead-free 3AB very fast-acting cartridge fuse designed for protection of Silicon Controlled Rectifiers and similar solid-state devices in appliance and utilization equipment. It is available in ampere ratings from 1 A to 30 A, with voltage ratings of 250 V (1–10 A) or 65 V (12–30 A), and features a ceramic body with nickel-plated brass caps. The fuse exhibits very fast response characteristics, with opening times of 4 hours minimum at 100% of ampere rating and maximum opening times of 0.2 seconds (1–10 A) or 1 second (12–30 A) at 250% of ampere rating. It operates across a temperature range of -55 °C to +125 °C and is RoHS compliant and lead-free, meeting UL Standard 248-14 and receiving approvals from UL, cUL, PSE, and CE agencies. This fuse is ideal for supplementary protection in circuits requiring rapid response to overcurrent conditions, particularly in power electronics and semiconductor applications.
