STYLISH DESIGN AND LEADING-EDGE TECHNOLOGY

L egrand combines stylish design, leading- edge technology and over 500 control functions, to deliver complete electrical and device-charging solutions for bedrooms. The Arteor range – which encompasses eve- rything from simple switches to the most ad- vanced home automation systems – enables users to create their own scenarios, which can be altered at any time to suit changing require- ments. Arteor mechanisms are available in white and magnesium, with a selection of 17 cover plate design options, in various colours, with plastic, metal and wood finishes. For added security and greater comfort, the Legrand team recommends including a min- iature Arteor emergency lighting device in the

bedside combination. This light illuminates im- mediately in the event of a power outage and although the lighting unit is small, its illumina- tion is powerful. The light fitting is easily unclipped from the mechanism and used like a conventional torch – a handy facility when a room is sud- denly plunged into darkness. 2 400 mA intel- ligent USB technology allows for fast charging of two USB connected devices with balanced load sharing. To add functionality, convenience and en- hanced aesthetics to any installation, the modular Arteor wiring devices are combined seamlessly with wireless chargers for mobile devices. For convenient mobile phone charging, all a

SAVE SPACE USING NEW RANGE OF CONTACTORS

A COMPLETE RANGE OF MOULDED CASE CIRCUIT BREAKERS UP TO 3200 A

E ngineered to provide the most compact contactor solution, the WEG CWB range of devices offers a width space saving of up to 18%. Add to this that the range was de- veloped according to IEC 60947 and UL 508 international standards and you will understand why this new generation contactor is finding such favour with electrical contractors. Developed in two frame sizes, the new WEG CWB line of contactors meets a range of industrial and domestic application require- ments. The first contactor in the range, cover- ing up to 38 A, has a width of only 45 mm while the second contactor, ranging from 40 to 80 A, has a width of 54 mm. Two mounting options, standard DIN rail or oblong mounting holes, make interchangeability easy. Significantly, the space saving offered by the WEG CWB contactors, especially when compared to similar product ranges, will allow contractors to use six contactors where previ- ously only five could be used. Another innovative engineering feature is the use of WEG’s Zero-Width mechanical in- terlocking system. Traditionally, contactors use

CWB contactors and because the coil con- sumes such low current it is possible to allow direct switching from PLCs without the need for interface relays. This facilitates space and cost savings for the end-user.

a mechanical interlock device that is external to the contactor. The Zero-Width system fa- cilitates quick and easy mechanical interlock- ing between contactors, without the need for tools. In addition, this feature allows the user to build a reversing starter up to 38 A with a total width of only 90 mm. Built-in front 1NO+1NC auxiliary contacts not only further enhance the space saving benefit of the WEG CWB contactors, but also eliminate the need for contractors to purchase additional auxiliary contacts. This feature also offers greater flexibility as it facilitates optimi- sation of the internal space in electrical pan- els. In another innovation, the contactors have been engineered with integral surge suppres- sor blocks without increasing the physical size of the devices. This limits undesired interfer- ence which could be caused during the open- ing of the contactor coils and allows for the front mount surge suppressor to be easily re- moved without the use of special tools. Energy saving is achieved through the low consumption of the coils used in the WEG

A ll the circuit breakers in the SACE Tmax T-range from ABB, both three-pole and four-pole, are available in fixed version; sizes T4 and T5 in the plug-in version, and T4, T5, T6, and T7 also in the withdrawable version. High values of short circuit breaking ca- pacity are guaranteed at different voltage levels, without compromising overall dimen- sions, while thermomagnetic and electronic trip units are available for use in ac/dc or in ac only. It is possible to interchange trip units keeping the same breaking part, so that in- stallation can be upgraded with fewer costs. A complete range of electronic trip units is suitable for different level of protection, enhancing selectivity values with Early Fault Detection and Prevention algorithm.

A SOUTH AFRICAN LEGACY UPGRADED T he PSO-1 socket outlet box, made by Allbro, has been a familiar sight in homes and public spaces around South Africa for more than 40 years. The tried and tested little enclosure has proven itself in some of the harshest environments and has remained the industry standard in the face of numerous foreign products being offered. While the trusty and familiar favourite PSO-1 will still be available, there has been an increasing number of requests for the com- pany to provide the option of an up market version. Allbro has called its newest arrival the ‘PSO-1 Stealth’. At first glance it is apparent that its appearance is dra- matically different. Looking more closely, it becomes evident that the new product also introduces some noteworthy features. The PSO-1 Stealth has an IP level of 66, which means that it keeps the electrical socket dry even when faced with a powerful water jet.

The Stealth is also equipped with cams and a padlock point for applications that need to be secured. The company believes that the most important feature to have been added is the in-wall mounting capability. By cutting the base on a cut line provided, the base can be mounted precisely in the space of two standard bricks. The use of GRP (Glass Reinforced Polyester) is very important because of the characteristics associated with the material: • Mechanical strength of GRP does not deteriorate like plastic materials that be- come brittle when their molecular structure is compromised by UV exposure. • There is also no deflection with high temperatures so the sealing of lid to base on these products remains predictable over long periods of time. • The material does not ignite when it comes into contact with electrical circuits so it is not a fuel source for an electrical fire (glow wire: 960 ° C) • The impact resistance of the enclosure is IK10 so it does not break easily when bumped. Allbro has invested heavily in local design and toolmaking capabilities over the past six years. The result has been that the bulk of the company’s business is now generated from new products. Local designs, local toolmaking, local materials, and local manufacture make this product thoroughly South African.
