The IP20 rating applies with conductors connected, so it's a panel-interior device; no washdown or outdoor exposure. Sealable with a lockable cover if the installation requires tamper-proofing. Halogen-free and silicon-free construction, which matters for environments where outgassing during a fault could contaminate sensitive equipment.
The 5SL4406-7 is rated 10 kA breaking capacity per both EN 60898 and IEC 60947-2 at 400 V AC. That's the same rating across both standards, so you don't need to derate or double-check which certification governs your application.
The 5SL4363-7 is a 3-pole version (54 mm wide) while the 5SL4406-7 is 4-pole (72 mm wide). Same 76 mm depth and 90 mm height, same DIN-rail mounting, same C-curve and 10 kA rating. It fits the same enclosure depth but needs an extra 18 mm of DIN-rail width — so a panel designed for the 3-pole unit will need a wider rail or a different backplate layout to accept the 4-pole.
The 5SL4406-7 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or price is published here.
