The copper nickel chemistry of our Cuprothal product line is ideal for fuse and circuit breaker applications. Materials come in a range of resistivities to allow adjustment of circuit interruption at the load you require.
| Kanthal CuNi alloys | Max. continuous operating temp. ºC (ºF) | Resistivity at 20ºC (68ºF) Ω mm2/m (Ω/cmf) |
|---|---|---|
| Cuprothal 294 (aka Cuprothal 49) wire | 600 (1110) | 0.49 (295) |
| Cuprothal 180 (aka Cuprothal 30) wire | 400 (750) | 0.30 (180) |
| Cuprothal 90 (aka Cuprothal 15) wire | 400 (750) | 0.15 (90) |
| Cuprothal 60 (aka Cuprothal 10) wire | 300 (570) | 0.10 (60) |
| Cuprothal 30 (aka Cuprothal 5) wire | 300 (570) | 0.05 (30) |
