Compact starter reduces wiring overhead

Second Quarter 2008 Electrical switching & drive systems & components

With the Sirius 3RA6 compact starter, Siemens Industry Automation (IA) has introduced a new low-voltage switchgear product for three-phase AC standard motors up to 32 amps. The functions of overload relay, circuit breaker and contactor are combined in the device. This reduces installation and wiring overhead for the user and creates more space in the control cabinet. The new compact starter has its own connection system for power supply and an optional mounting module for simple connection to AS-Interface.

Having five current settings up to 32 amps and three wide voltage ranges of 24, 42 to 70 and 110 to 240 volts for AC/DC current, the devices, available as direct starters or reversing starters, cover a large percentage of the application range.

Using the associated Control Kit, the user can perform an early check on the wiring and motor direction even before the plant starts up. This can prevent faults and increase plant availability, as can safe shutdown at the end of service life, separate indication of overload and short-circuit, and auto reset following overload trip. Removable spring-loaded and screw-type terminals simplify device replacement for service purposes.

For connection to the main circuit, the user can simply plug the Sirius 3RA6 compact starter into the associated, pre-wired infeed system, significantly reducing the wiring overhead. This infeed system can be flexibly expanded to suit the plant by adding additional slots and other Sirius industrial controls components such as 3RV1 circuit breakers.

When used in conjunction with the AS-Interface all the diagnostics and status data of the compact starter are forwarded directly to the higher-level controller.
