Frequently asked questions

What is the benefit of the integrated diode in the Siemens 3RT2016-1FB41?

The integrated diode in the Siemens 3RT2016-1FB41 acts as a freewheeling or suppression diode. It protects the control circuitry from voltage spikes generated by the collapsing magnetic field when the DC coil is de-energized, thus preventing damage to sensitive electronic components.
