About SIEMENS 3TF 50 DOL STARTER

A DOL starter (also known as a direct on line starter or across the line starter) is a method of starting a 3 phase induction motor. In a DOL Starter, an induction motor is connected directly across its 3-phase supply, and the DOL starter applies the full line voltage to the motor terminals.

Integrated Protection & Durable Build

Engineered with advanced short circuit and thermal overload protection, the SIEMENS 3TF 50 DOL Starter ensures optimal safety for your motors. The use of high-quality materials and a sturdy dustproof, smooth-coated enclosure promote longevity and reliable operation even in demanding industrial environments.

Efficient & User-Friendly Design

Enjoy easy installation thanks to its standardized dimensions and wall-mounted configuration. With screw-type terminals and a straightforward connection process, the starter supports efficient maintenance. Its IP20 rating and high insulation enhance protection for both users and motors during operation.

Wide Application Versatility

Optimized for industrial and motor control uses, the 3TF 50 DOL Starter accommodates a broad voltage input (230/415 VAC) and performs reliably in ambient conditions from -5C to 55C and up to 95% humidity. It is ideal for diverse applications requiring enhanced motor safety and robust operational reliability.
