What is the purpose of the C-curve in the Siemens 5SY6230-7 circuit breaker?
The C-curve on the Siemens 5SY6230-7 means it is designed to trip at higher currents (5 to 10 times the rated current) compared to a B-curve. This characteristic is ideal for circuits that have moderate inrush currents, such as those powering motors or lighting ballasts, preventing nuisance tripping during startup.
