Frequently asked questions

What is the significance of the 'C' in the Siemens 5SX2 118-7's tripping curve?

The 'C' in the Siemens 5SX2 118-7 indicates a Type C tripping characteristic. This means the breaker will trip between 5 to 10 times its rated current (15A in this case) during a short circuit. This makes it suitable for circuits with moderate inrush currents, like those from fluorescent lighting or small motors.
