Product details

What the D-curve and breaking capacity mean for your panel

The Siemens Betagard 5SL7306-8RC is a 3-pole miniature circuit breaker with a D tripping characteristic, rated 6 A at 415 V AC. Breaking capacity is 15 kA per EN 60898 and 20 kA per IEC 60947-2, so it clears high-fault currents in industrial distribution without cascading upstream. The 18 mm width per pole (3 modular units total) snaps onto a standard DIN rail, and the 76 mm depth leaves room for wiring behind the gland plate.

Where it fits — panel integration and environment

Vibration-rated per IEC 60068-2-6, which matters for machine-mounted sub-panels on conveyors or compressors.

Compliance and documentation signals

Sealable design allows lockout/tagout. The Betagard brand is Siemens' value line for commercial and light industrial panels, distinct from the SENTRON residential range.

Frequently asked questions

What is the breaking capacity of 5SL7306-8RC?

15 kA per EN 60898 and 20 kA per IEC 60947-2 at 415 V AC.

Will 5SL7306-8RC drop into a panel specified around 5SL4363-7 without rewiring?

The 5SL7306-8RC is 18 mm wide (3 modular units), while the 5SL4363-7 is 54 mm wide (also 3 modular units) — same footprint. Both are 3-pole, same depth (76 mm) and height (90 mm), same DIN-rail mounting. The key difference is the D-curve vs C-curve and the higher breaking capacity on the Betagard (15/20 kA vs 10 kA). No rewiring needed for the busbar or load connections, but verify the trip curve matches your load type.
