Whether current-dependent or temperature-dependent: A solid-state overload relay delivers real cost-effective value. Especially when it is a device from the SIRIUS product family. Just two of the many advantages of the SIRIUS 3RB2 overload relay: The large current setting ranges reduce the variant quantity compared to thermal relays by up to 90% and the lower capacity loss reduces energy consumption by up to 98%.

Benefits:
- More accurate with respect to thermal protection
- Settable class type
- Compact size due to inbuilt CT for select range
