Additional Details:

The S803N-C100 features a C-characteristic tripping curve, meaning it trips faster for short circuits than for overloads, making it suitable for circuits with moderate inrush currents. The 'N' likely indicates the number of poles (in this case, three poles). The C100 indicates that it is a 100A circuit breaker. The thermal-magnetic trip mechanism provides both overload and short-circuit protection. Its high breaking capacity allows it to safely interrupt high fault currents. The trip-free mechanism ensures that the breaker will trip even if the handle is held in the ON position during a fault. It is designed for easy installation on standard DIN rails. The visual contact position indication provides a clear indication of the breaker's status.
