Product details

The 10 kA breaking capacity per both IEC/EN 60898 and IEC 60947-2 tells you it can safely interrupt a fault current up to 10 kA at 400 V AC without welding contacts or cascading upstream — that covers most residential and light commercial panelboards. Rated 3 A at 30 °C, derated to 2.88 A at 40 °C and 2.69 A at 55 °C — if your panel runs hot, you need to account for that thermal derating curve when sizing the load.

Snap-on DIN-rail mounting in any position — no orientation restrictions. Occupies 4 modular width units at 72 mm wide, 76 mm depth, 90 mm height. Installation depth 70 mm. Sealable for tamper-proof applications.

Mechanical service life 10 000 operating cycles. Suitability marked for residential buildings and infrastructure.

Frequently asked questions

What are the key ratings of the 5SL4603-7?

Rated 3 A at 30 °C with a C-curve trip characteristic, 10 kA breaking capacity per IEC/EN 60898 and IEC 60947-2, rated voltage 400 V AC, max operating voltage 440 V AC multi-phase. 4-pole 3P+N configuration.

Will 5SL4603-7 drop into a panel specified around 5SL4363-7 without rewiring?

Both are 4-pole SENTRON MCBs with the same DIN-rail footprint and 4 MW width. The 5SL4603-7 is a 3 A C-curve; the 5SL4363-7 is a higher-current variant. If your panel was wired for a 4-pole 3P+N MCB, the 5SL4603-7 fits mechanically — but verify the current rating matches your branch circuit protection requirements before swapping.

Where can I buy the 5SL4603-7?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for the best market posture on this active-production SENTRON MCB.
