Siemens Soft Starter, Soft Start, 22 kW, 400 V ac, 3 Phase, IP00

Having trouble firing up your three-phase asynchronous motors? Get them off on the right foot with this soft starter from Siemens. It uses two-phase control and hybrid switching technology that combines a thyristor and mechanical bypass. This helps you get a handle on unstable line voltages and limit in-rush currents and torque spikes. To give you a simple and safe way to power up and stop your machines, there are two dials on the front for setting the ramp-up time and starting voltage. The unit's small dimensions of 160 (L) x 55 (W) x 170mm (D) mean it slots neatly into compact control cabinets. Thanks to a high output of 22kW, this is an effective choice for pumps, conveyors and other belt-driven systems.

• Works with AC and DC supply voltages for versatility
• Screw terminals ensure your connections are firm and stay reliable
• Operates safely at temperatures between -25°C and +60°C

Yes. This device's flexible design makes it easy to add a link module (621-1830) that lets you connect it to a motor protector (211-5956) and clip in auxiliary conductor terminals (210-3502).
