Siemens has developed an innovative line of enclosed IEC motor controls that feature components form the SIRIUS modular system.
Placing the most advanced motor control technology "in a box" makes this new line ideal for industrial and construction applications that use fans, pumps, or blowers.
See how the pre-fabricated and ready-to-install 3RE4 Enclosed IEC line will increase your plant's efficiency.
- Lower cost alternative to enclosed NEMA products
- Customizable with factory and field modifications
- RoHS-compliant (environmentally friendly)
Available in a variety of sizes from standard to extra-large, Siemens’ enclosed IEC motor controls can be more easily tailored to specific applications to help ensure customers are paying for the right sized product. They also provide a low-cost alternative to enclosed NEMA products.
The new 3RE4 line of enclosed IEC motor controls include NEMA Type 1, 3, 3R, 4, 4X and 12 enclosures, with SIRIUS contactors and overload relays and SIRIUS ACT pilot devices. Starters are available with thermal or solid-state overload relays for single-or three-phase motors in reversing or non-reversing applications.
The SIRIUS line of solid-state overload relays is designed and calibrated to be used with IE2, IE3 and IE4 motors, providing less nuisance tripping due to their high inrush capabilities. The wide range of overload relay settings also allows for inventory reductions.
What sets the enclosed IEC line from Siemens apart?
The Enclosed IEC line has been developed with the most highly-evolved and technologically- advanced product family – the SIRIUS product portfolio, “in a box.” Modular and globally accepted, SIRIUS is the most advanced line of products on the market providing you with updated technology in the familiar gray box.
Siemens devices are manufactured in accordance with environmental guidelines and contain eco-friendly and reusable materials. They comply with important worldwide standards and approvals (RoHS).
Siemens newly-designed contactors and motor starters are suitable for high-efficiency motors (IE3/IE4) which help you reduce nuisance tripping, save on energy costs, reduce parts on the shelf/inventory, and increase plant uptime.
Siemens makes it easier to order with quick order guides and flexible offers for a range of applications. These devices can either be modified in the factory or field to include pilot devices, CPTs, and other control components. You have the option to order the enclosed assemblies with easy to select factory modifications or add these mods on-site using our quick-to-install field kits and accessories.
