Product details

It breaks 50 kA at 400 V AC per IEC 60947-2 — that's the industrial-grade SCCR, not the lower 10 kA residential rating you see on the 5SL or 5SY siblings.

Mounts on standard DIN rail or via screw fixing — the evidence lists both. Installation depth is 92 mm, and it occupies 4.5 width units (about 81 mm on the rail). Tunnel terminals at top and bottom accept the conductors; the housing is IP20 with conductors connected, so it's meant for enclosed panels, not open wet areas. Sealable cover is standard, and touch protection is built in.

Rated for -40 °C to 75 °C ambient, with 95% humidity at 55 °C. Shock resistance is 150 m/s² at 11 ms half-sine (IEC 60068-2-27), vibration 50 m/s² at 25-150 Hz and 60 m/s² at 35 Hz. Mechanical life is 20 000 switching cycles typical.

Frequently asked questions

How do I get current pricing and availability for 5SP9306-7KC47?

Submit an RFQ through the storefront. The part is sourced to order through independent distribution; availability and current pricing are confirmed at quote time.

What is the difference between 5SP9306-7KC47 and the 5SL4363-7?

The 5SL4363-7 is a 3-pole C-curve MCB but rated only 10 kA per IEC 60947-2, versus 50 kA on the 5SP9306-7KC47. The 5SL also has a shallower 70 mm installation depth and 10 000 mechanical cycles, compared to 92 mm and 20 000 cycles here. They share the same 400 V AC rating and DIN-rail mount, but the 5SP9 is the high-breaking-capacity industrial variant.

Will 5SP9306-7KC47 drop into a panel specified around 5SL4363-7 without rewiring?

It mounts on the same DIN rail and uses the same tunnel terminals, but the 92 mm installation depth is 22 mm deeper than the 5SL's 70 mm — check enclosure depth clearance before swapping. The 50 kA breaking capacity is higher, so no coordination issue downstream, but the wider 4.5 width units (vs 3 on the 5SL) may crowd adjacent devices.

What compliance documentation does this brand provide for 5SP9306-7KC47?

The part is rated per IEC 60947-2 for industrial applications. It carries IP20 protection (with conductors), pollution degree 3, and overvoltage category III. Halogen-free and silicon-free construction is confirmed. Specific RoHS/REACH/UL declarations should be requested at quote time.
