Load Feeders

When it comes to load feeders, a fundamental question arises as to whether they should have fuses or no fuses. The SIRIUS system allows fuseless combinations to be configured using circuit-breakers and contactors or with fuses using contactors and overload relays.

The direct online starter

A simple starter configuration comprising circuit-breaker and contactor without starting steps or soft starting is the right solution for drives such as pumps, saws and similar applications. However, this also applies to large drives, for example, amusement rides and rolling mills can be directly started with SIRIUS. A direct online start is characterised by the high motor starting torque.

SIRIUS completely covers the power range from 0.06 to 250 kW at 400 V.
