The 5SL4210-6CC: The B-curve (tripping characteristic class B) means the MCB trips at 3–5× rated current — designed for resistive and general-purpose loads in residential and infrastructure panels, not for high-inrush motor circuits. Rated 10 A continuous, so it protects a branch circuit sized for that load. Two-pole (2P) switching with no neutral pole switching — the neutral is not broken, so this is for single-phase or two-phase circuits where the neutral is common. Rated for 440 V AC maximum in multi-phase operation, which gives headroom above the 400 V nominal.
Accepts solid or stranded conductors from 0.75 to 25 mm², with screw terminals torqued to 2.5–3 N·m. Sealable and touch-protected per IP20 with connected conductors. Ambient temperature range -25 to +55 °C operating, -40 to +75 °C storage.
