The motor starter combines several functions such as direct-on-line and reversing starting, and overload protection in one device. What is more, in a group configuration, short-circuit protection up to 55 kA can be achieved with just one motor starter protector.

The hybrid switching technology uses low-wear semiconductors for switching the motor on and off, and in the operating phase it relies on energy-saving relay technology, thus ensuring the durability of the starters and a high level of energy efficiency.

Infeed in the main circuit for several motor starters can be handled quickly and simply via a special infeed system. They are connected to one another by means of a three-phase busbar - with a minimum of wiring.

The combination of fail-safe motor starters with SIRIUS 3SK safety relays enables the simple implementation of safety-related disconnections. The Safety versions are certified to SIL3/ Pl 3 Cat. 4 and ATEX.
