Can the Siemens 5SL4220-7 handle motor starting currents?
The Siemens 5SL4220-7 features a C-curve, which can tolerate moderate inrush currents typical of some motor startups. However, for motors with very high starting currents (e.g., direct-on-line across the line starters), a D-curve breaker might be more appropriate to prevent nuisance tripping.
