Siemens 3RK1308 Soft Starter, DOL, 500V ac, 1.1 kW, 3 Phase, IP20

Prevent high loads from damaging motors as they power up with this soft starter from Siemens. It's a direct-online type of starter that keeps wiring simple and allows machines to start up quickly. As a hybrid device using relays and semiconductors, it starts motors gently and efficiently to keep your equipment working at its best. A power rating of 1.1kW makes this a suitable option for high-performance systems, including conveyors, pumps and three-phase motors. Fail-safe functionality ensures the starter shuts down motors in the event of a blockage, minimising damage. It's also fused to safeguard against short circuits and, to help prevent overloads, it has built-in solid-state motor protection. An adjustable trip means you can tailor the safety levels to your application.
