The Siemens Betagard 5SL7104-7RC is a 1-pole miniature circuit breaker with a C-curve trip characteristic, rated 4 A at 240 V AC single-phase and 415 V AC multi-phase.
The 4 A rating governs the continuous thermal load; expect nuisance trips if the branch draws above 4 A sustained. That dual rating gives the buyer flexibility to spec this into either a commercial or industrial BOM without swapping part numbers. Rated for 240 V AC single-phase and 440 V AC multi-phase, it covers standard 230/400 V three-phase panels. The 50/60 Hz frequency range is universal for mains supplies worldwide.
Panel integration and environment
Mounting position is unrestricted. Sealable — the toggle can be locked in the off position with a padlock, meeting lockout/tagout requirements. Halogen-free and silicon-free construction reduces toxic gas and silicone outgassing in sensitive environments.
