The 5SL3150-6: Snaps onto DIN rail at 18 mm per pole (1 width unit). Installation depth is 70 mm; overall depth with terminals is 76 mm. Mounting position is unrestricted — vertical, horizontal, upside-down — which helps when you're shoehorning it into a crowded enclosure. Terminals accept 0.75 to 25 mm² solid or stranded copper, torqued to 2.5–3 N·m.
Lifecycle stage is current — no phase-out, no last-time-buy on the horizon. That means you can spec it into a design without worrying about a forced redesign mid-cycle. Compliance documentation (RoHS, REACH, UL, IEC) is standard for the SENTRON line; the part carries IP20 protection with conductors connected, overvoltage category 3, and energy limiting class 3.
Rated for residential buildings and infrastructure — think distribution boards, sub-panels, lighting circuits, general-purpose branch protection. The B curve trips between 3 and 5 times rated current, which suits resistive and light inductive loads where you don't want nuisance trips from inrush. Ambient range is -25 to +45 °C operating, -40 to +75 °C storage. Halogen-free and silicon-free construction for environments sensitive to outgassing.
