Because SIRIUS is a modular system, the standard devices fit together opti-
mally both mechanically and electrically. The fuseless load feeders can
therefore be assembled quickly and easily in all four frame sizes. To this end,
the circuit breaker and the contactor are connected to the corresponding kit.
There are kits for reversing feeders for mounting on:
• Rail, frame sizes S0, S2, S3: mounting kit for reversing operation
frame size S00: wiring kit for reversing operation
• Busbars, frame sizes S00, S0, S2: mounting kit for reversing operation
The following illustration shows how to assemble the fuseless load feeder
of frame size S00 for reversing operation and rail mounting:

The fuseless load feeders are also available fully assembled:
• Up to 22 kW in the case of direct starters
• Up to 11 kW in the case of reversing starters
