Fits standard 4-module enclosures and leaves room for adjacent breakers or busbars. Operates from -40 °C to 75 °C, with derated current above 30 °C: 4.4 A at 30 °C, 4.2 A at 40 °C, 4.1 A at 45 °C, 4 A at 50 °C, 3.9 A at 55 °C, 3.8 A at 60 °C. In a hot panel, size up if the load runs near 4 A continuous. ## DC and AC ratings Rated for single-phase AC up to 440 V and DC up to 72 V max. The DC rating is lower than the AC because DC arcs don't self-extinguish at zero-crossing — the Z curve's fast magnetic trip helps here, but stay within 72 V for DC circuits.","metaTitle":"Siemens Betagard 5SL4104-0RC MCB, 4 A, 1-pole, Z characteris","metaDescription":"Siemens Betagard 5SL4104-0RC miniature circuit breaker, 4 A, 1-pole, Z characteristic, 10 kA per EN 60898.
