Description Detailed Specifications
 
The Siemens 3RB2056-1FW2 solid-state overload relays are suitable for customers from all industries who want to provide optimum inverse-time delayed protection of their electrical loads (e.g. motors) under normal and heavy starting conditions (CLASS 5 to CLASS 30), minimize project completion times, inventories and power consumption, and optimize plant availability and maintenance management.

These Siemens Sirius solid-state overload relays have been designed for the protection of three-phase motors in sinusoidal 50/60 Hz voltage networks. The relays are not suitable for the protection of single-phase AC or DC loads. The 3RU11 thermal overload relay or the 3RB22/3RB23 solid state overload relay can be used for single-phase AC loads. For DC loads the 3RU11 thermal overload relays are available.
