Solid-State Overload Relay
Solid-State Overload Relays with screw-type connections reliably protect loads as well as other switching and protective devices in the respective load feeder from overload, phase imbalance and phase failure. Overload Relays are easily fitted to the Siemens Contactor range or for separate mounting alternatively the stand alone Terminal Brackets (3RB2913) can be used.
Overload Relays ensure real commercial added value: In the main circuit, the electronic overload relays for standard applications are responsible for current-dependent overload protection of electrical loads (e.g. motors). Due to the wide current setting ranges, complete series of motors are covered with just a few types. An electrical Manual/ Automatic reset is incorporated as well as 1 NO and 1 NC auxiliary contacts. Solid-State Overload Relays are available in six sizes dependant upon kW rating and current setting up to 630A, as well as kW and A rating the physical size also changes.
