Global industrial power controls

Networks & Communication

XT family of IEC Power Controls includes globally rated contactors, starters, overload relays, manual motor protectors, and combination motor controllers.

XT line of IEC Power Control solutions for motor protection and control encompasses a variety of industrial control products for panel builders and OEMs, including contactors, starters, overload relays, manual motor protectors, and combination motor controls. Featuring open and packaged control options, the line is applicable worldwide with its global ratings, smaller product sizes for tight panel spaces, and ease of installation and maintenance.

XT reduces mounting and wiring time by allowing standard components to be combined without tools, quickly and error free. It offers UL, CSA, CE, and CCC approvals, as well as RoHS compliance. Four frame sizes cover contactor ratings up to 150 A, making it easier to lay out panels. ECX, the enclosed offering, has a back panel sized for metallic or non-metallic enclosures.

Products are available in a wide range of control voltages—12-600 V ac and 12-220 V dc— to meet many requirements. Installation and maintenance are simplified by DIN rail mounting for devices up to 65 A, reversing and star-delta (wye-delta) wiring link kits, and modular combination motor controllers.

XT meets stringent user and environmental safety requirements. IP20-rated terminals are finger and back-of-hand proof. Contactors up to 400 A feature box terminals with dual terminal chambers to form a better connection and lower the possibility of flash.

Included in XT line are XTPB pushbutton (up to 25 A) and XTPR rotary (up to 63 A) actuated Manual Motor Protectors, accessories, and enclosures; contactors and starters for applications from 7-2,000 A; and manual/combination motor controllers (MMC and CMC). Rated to both IEC and UL standards, MMC and CMC are available as open non-reversing or reversing devices. Eaton Corp.

Wireless LAN for data exchange


Scalance W wireless LAN from Siemens E&A ensures critical data are received and transmitted when and where they’re most needed.

Scalance W wireless LAN from Siemens Energy & Automation operates over three wireless protocols in one system. It provides data rates of up to 54 Mbits/second and operating speeds of 2.4 GHz (802.11b and 802.11g) or 5 GHz (802.11a).

Featuring deterministic control for client modules, the LAN frees up bandwidth and ensures critical data are received and transmitted when and where they are needed most. Scalance W completes Siemens' line of industrial Ethernet infrastructure products, complementing its Scalance X industrial Ethernet switches and Scalance S security modules.

Raj Rajani, Siemens product marketing manager, says the product delivers a complete industrial wireless LAN (IWLAN) solution, providing access points, client modules, varying types of antennas, power supplies, cables, and connectors. "We've incorporated all of the convenient features associated with wireless access and pushed them to the next level by incorporating superior data security, critical client data reservation, and the flexibility of 802.11b/g/a open standards," says Rajani. "The industrial ruggedness of the product eliminates the need for enclosures. As a result, costs are reduced and users gain enhanced installation flexibility because the system may be mounted directly on machines, ceilings, or roofs."

Advanced industry standard security features designed into the system are easily managed without special training. Scalance W protects against unauthorized access by incorporating Wi-Fi Protected Access (WPA) security and Advanced Encryption Standard (AES) with 128-bit encryption. It operates at temperatures between -20 and 60°C, and features IP65 protection against dust, water, and foreign bodies. It is easily configured and deployed using a Web-based management tool included with the product. Siemens Energy & Automation
