RS15 Series
- RS15：Standard aR‑type fast‑acting semiconductor cartridge‑type fuse‑link, size Ø10.3×31.5mm, rated working‑voltage 500/690V AC. It adopts cylindrical cap‑type plug‑in installation and works with semi‑enclosed or open‑style fuse bases. The available rated‑current covers 0.5‑32A, and non‑standard customized current specifications marked with asterisk are optional. It delivers a 100kA breaking‑capacity under 500V and 50kA under 690V, with maximum power dissipation no higher than 7.5W.
- RS15A：Compact short‑length striker‑equipped semiconductor fuse, dimension Ø10.3×25.8mm, rated‑voltage 250V AC. The front‑end striker pops out after fusing to actuate the auxiliary micro‑switch for remote fault‑alarm signal output, suitable for compact‑sized semiconductor‑protection circuits.
- RS15B：Rear‑end striker variant with dimension Ø10.3×31.5mm, rated‑voltage 250/500V AC. Its rear‑fitted striker matches multi‑types of common fuse holders, applied for circuits needing remote monitoring.
- RS15C：Medium‑size fast‑blow fuse‑link of Ø10.3×34mm, rated‑voltage 380/500V, widely‑used for general‑purpose semiconductor‑loop protection.
- RS15D：Long‑size high‑voltage adapted model sized Ø10.3×57mm, rated‑voltage up to 600V, rated‑current range 2‑32A.
Key reminder：The RS15‑series belongs to aR‑class quick‑action semiconductor‑special fuses. Never interchange them with RO15 gG general‑purpose fuses. Though sharing the same outer diameter, they carry totally‑different melting characteristics. Improper replacement will lead to severe burnout of semiconductor components.
