Product details

It breaks fault currents up to 15 kA per EN 60898 and 20 kA per IEC 60947-2 at 415 V AC, making it suitable for industrial panel protection where high fault current capacity is needed — the 20 kA IEC rating gives headroom for coordination with upstream switchgear in high-capacity distribution boards.

Snap-mounts onto standard DIN rail. Occupies 3 modular width units (18 mm each) for a total 54 mm panel width.

Halogen-free and silicon-free construction. Sealable design allows lockout/tagout. Vibration-resistant per IEC 60068-2-6. Power loss 1.6 W per pole in hot operating state. Suitable for industrial operation per the manufacturer's designation.

Frequently asked questions

Where can I buy 5SL7306-7RC?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the difference between 5SL7306-7RC and 5SL4363-7?

The 5SL4363-7 is a SENTRON-branded 3-pole C-curve MCB with a lower breaking capacity (10 kA per both EN 60898 and IEC 60947-2) and higher per-pole power loss (5 W). The Betagard 5SL7306-7RC offers 15/20 kA breaking capacity at 1.6 W per pole, making it better suited for higher-fault industrial panels. Both share the same 76 mm depth and 90 mm height, but the 5SL4363-7 is 54 mm wide (3 MW) — same footprint as the 5SL7306-7RC, so it drops into the same DIN-rail position without rewiring the busbar.
