Product details

The 4.5 kA breaking capacity per EN 60898 covers most residential and light commercial panelboard duty; the 5 kA rating per IEC 60947-2 gives a bit more headroom for industrial distribution boards where fault currents run higher.

The 5SL3316-7 occupies 3 modular width units (54 mm total) on a DIN rail, with a 76 mm depth and 90 mm height — standard SENTRON footprint that drops into any 18 mm-pitch enclosure. Mounting position is unrestricted, so it works in vertical or horizontal busbar arrangements.

Accessories and auxiliary devices

The breaker accepts supplementary devices (shunt trip, undervoltage release, auxiliary contacts) — the terminal interface is standard across the SENTRON 5SL series.

Frequently asked questions

What is the breaking capacity of the 5SL3316-7?

The 5SL3316-7 is rated 4.5 kA according to EN 60898 and 5 kA according to IEC 60947-2, both at 400 V AC. The IEC 60947-2 figure is the one to use for industrial distribution board coordination.

Will the 5SL3316-7 fit in a panel originally built for the 5SL4363-7?

Yes, the 5SL3316-7 shares the same 54 mm width (3 MW), 76 mm depth, 90 mm height, and DIN-rail mounting as the 5SL4363-7. It will physically swap without rewiring. The difference is interrupting rating: the 5SL4363-7 is 10 kA per both standards; this unit is 4.5 kA / 5 kA. Verify coordination with the upstream breaker before substituting.

Where can I buy the 5SL3316-7?
