The 3RB21 solid-state overload relays are suitable for customers from all industries who want to guarantee optimum inverse-time delayed protection of their electrical loads e.g. motors under normal and heavy duty conditions, minimize project completion times, inventories and power consumption, and optimize plant availability and maintenance management.
The 3RB21 solid-state overload relays have been designed for the protection of induction motors in sinusoidal 50/60 Hz voltage networks. The relays are not suitable for the protection of single-phase AC or DC loads.
