24 Hours online(Perfessional response)

RS14
Standard semiconductor fuse without striker. Dimension Ø8.5×31.5 mm, rated voltage 500 V AC. Only blow‑out indicator on end cap, no remote alarm output. Fits regular RT19‑16 fuse base. Current range 0.5‑25A.
RS14A
Front‑end striker version for semiconductor protection. Dimension Ø8.5×23 mm, rated voltage 250 V AC. Once the fuse operates, striker pops out from front cap to trigger external micro‑switch, realizing remote fault signal feedback. Mainly used for low‑voltage semiconductor loop requiring alarm function. Current range 0.5‑20A.
RS14B
Rear‑end striker semiconductor fuse. Dimension Ø8.5×36 mm, rated voltage 380/500 V AC. Striker ejects from rear side of fuse element, specially matching RT19‑16 gF1 base with auxiliary switch. Supports high‑voltage semiconductor circuit and remote alarm monitoring. Current range 0.5‑20A.Key reminder：RS14 series is aR fast semiconductor fuse, do not mix‑use with RO14 gG general‑purpose fuses. Even if outer dimensions are identical, protection characteristics differ completely, wrong replacement will cause semiconductor device burn‑down.
