SIRIUS Motor Starter Packages
SIRIUS Motor Starters for industrial and construction applications
March 6, 2023
Siemens has developed an innovative enclosed line of motor starters using their SIRIUS product family, placing the most advanced motor control technology “in a box.” To compliment their long standing “V” series made-to-order SIRIUS Motor Starters, the 3RE41 line offers a modular approach to ordering and configuring enclosed motor starters.
SIRIUS 3RE4 offers a wide selection of enclosed motor starter packages, contactors installed in NEMA 1 enclosures, which can be converted to 3-phase or 1-phase motor starters with the addition of an overload relay (sold separately). Packages are available with or without SIRIUS ACT control devices, pilot lights and control transformers.
SIRIUS ACT devices, control transformers and a variety of other devices can optionally be installed in the field, with the purchase of field installation kits. This versatility allows distributors to combine the benefits of custom-engineered starters with off-the-shelf availability. Protecting the performance of motors is a critical priority and one of the best ways to do so is with cUL certified SIRIUS Motor Starter Packages.
