3.3

Hybrid technology

The 3RM1 motor starter combines the benefits of semiconductor technology and relay

technology.
This combination is known as hybrid technology. The hybrid technology in the 3RM1 motor

starter is characterized by the following features:

Switching on

The inrush current in the case of motorized loads is conducted briefly via the

semiconductors.
Advantage: The relay contacts are protected. Longer service life is achieved thanks to

reduced wear and tear.

Current conducting

The continuous current is conducted via relay contacts.
Advantage: Relay contacts cause less thermal losses than semiconductors.

Switching off

Switch-off is implemented again via the semiconductor.
Advantage: The contacts are only slightly burdened by arcs. This results in increased service

life.
