April 2007 – A comprehensive range of miniature incandescent lamps including advanced Xenon filled types and matching drop-in replacement sockets is available from CML Innovative Technologies (CML-IT). Delivering a cost-effective solution with high luminous output, traditional incandescent lamps still have a valid role in many applications such as automotive, gaming, aviation and transport, where cost restrictions don’t warrant the use of still higher-priced, modern LED lamps.
Produced in Bury (United Kingdom) and Bamberg (Germany), CML-IT’s range of Xenon filled miniature incandescent lamps, for example, benefits from a long service life of 10000 hours, a cool wall temperature (about 30 degrees Celsius less than comparable Argon lamps), a very high colour temperature and high output in low watt versions. Compared with conventional incandescent lamps, Xenon filled types also offer power savings.
Miniature incandescent lamps generate significant sales of approximately $40M per year for CML-IT and recently prompted a major investment at the company’s production facility in Bury. A new socket machine was commissioned and will increase the production of sockets from 440000 units per week up to 660000 units per week. This will make it even easier for customers to directly source miniature incandescent lamps together with matching sockets from CML-IT.

Finder announces a new generation of its 14 Series electronic staircase timers, which have been designed for energy saving control of lighting in areas of temporary occupation. The latest models feature microprocessor control, and are targeted at lighting applications in stairwells, corridors, washrooms, storerooms and similar areas that only require illumination for short periods of time.
Designers, contractors and installers of lighting in commercial and residential property are continually looking for ways to reduce energy consumption by eliminating wasteful lighting in unoccupied areas, while addressing the growing need to illuminate more public areas for security and safety reasons in an economical way. Staircase timers such as the 14 series offer a cost-effective solution that is simple to implement even in small installations.
The 14.01 timer is a multi-function unit, while the 14.71 is a single function version. Both models have an on period that is adjustable between 30s and 20 minutes, so that a single timer is suitable for wide range of installations. This flexibility of operation means that specification is simplified and inventory levels can be kept to a minimum. A further single function model, 14.81, offers wiring compatibility with earlier mechanical models.
All the new timers feature zero-crossing load switching, which enables the switching of higher lamp loads and also offers the benefits of longer lamp and unit life and reduced RF interference. A switch-off early warning function on the 14.01 gives a user who is still in the area time to re-activate the timer before the light is turned off.
Multi-function features on the 14.01, accessed via a simple rotary function selector, include timed control with or without manual override, early warning, standard on/off, permanent on and maintenance function with extended 60 minute on time.
Each timer can be used with up to 30 illuminated pushbutton actuators, offering local control over a wide area and thus giving the user maximum opportunity to re-activate the timer before being plunged into darkness: this enhances safety, and is especially beneficial in stairwells.
All the 14 Series timers are housed in a 35mm rail mounting enclosure that is 17.5mm wide, and have a timing adjustment suitable for standard consumer unit.

Just 17.5mm wide for single pole versions and 52.5mm wide for triple-pole types, Moeller Electric’s new Xpole FAZ miniature circuit breakers (MCBs) have a breaking capacity of 15kA, in line with IEC/EN6094. This makes them an attractive and cost-effective choice for use in industrial applications where space is always at a premium, and high prospective fault currents are often encountered.
In addition to the standard B, C and D trip characteristics, Moeller is offering Xpole FAZ MCBs with the new Z, K and S characteristics, which are of particular interest to OEMs and designers of automation systems.
Specifically designed to protect sensitive electronic equipment, the Z characteristic has a short-circuit response current of 2 to 3 In, combined with quick-reaction overload protection. The K characteristic has a short-circuit response current of 8 to 12 In, which prevents nuisance tripping with three-phase loads such as motors, while the S characteristic with its exceptionally high 13 to 17 In short-circuit response provides a complete solution to the problem of protecting control transformers and other loads with very high inrush currents.
Moeller Electric's new Xpole FAZ MCBs are available with ratings from 0.5A to 63A, and are offered in single-, double-, three- and four-pole versions. All types comply with a broad range of national and international standards, including UL and CSA, there is even a special series of devices which fully comply with UL489.
A range of accessories, which includes auxiliary signalling contacts and shunt-trip mechanisms, provides additional functionality. To ensure fast and easy assembly, most accessories simply snap into place without the need to use tools. The breakers themselves are designed for convenient mounting on standard DIN rail.
The new compact Xpole FAZ MCBs are complemented by an extensive family of RCCBs, combined RCD/MCBs (RCBOs) and control devices. The PKNM combined RCD/MCBs offer triple protection in a single device, namely overload, short-circuit and residual current protection in the space of only two MCB widths. Catering for either B or C characteristics, they are available from 6A to 40A with rated fault currents of 30mA or 300mA.
Xpole type AZ MCBs are also available for use in applications where current ratings up to 125A and a switching capacity greater than 15kA is needed.

Many of you will have been aware that the JCB DIESELMAX car became the world’s fastest diesel-powered automobile in August when Wing Commander Andy Green drove it to a new record of 350.092mph (563.418kph) after two passes in opposite directions, within one hour, on Bonneville Salt Flats in Utah. But how many of you knew that the electrical circuits were protected by E-T-A circuit breakers?!
Sir Anthony Bamford, Chairman of privately owned JCB, was very clear why he wanted to build a JCB record-breaker when the project was started: “I am passionate about the importance of engineering excellence to Britain and I see using the JCB engine for this record attempt as a fantastic way of showcasing what British engineers can do. The JCB444 has been acknowledged as a remarkable piece of engineering, and this programme to build the world’s fastest diesel-powered automobile is precisely the sort of technical challenge that we should rise to.”
Powering the stunning, nine metre long JCB DIESELMAX car were two JCB444 diesel engines, developed with the help of Ricardo engineers to produce 750bhp each, five times the power needed to drive a JCB backhoe loader, and now the world’s most powerful diesel engine per litre. The JCB444-LSR engine displaces 5-litres, weighs 382 kg (dry), and produces 750bhp at 3,800 rpm on a relatively low 10.5:1 compression ratio and in excess of 1500 Nm of torque at 2,500 rpm.
The distribution panel was designed and built by R&D Vehicle Systems, based in Banbury. Rob Millar,director of RDVS, explained: “R&D Vehicle Systems is a specialist designer and supplier of electrical systems for military and niche vehicle manufacturers. We were delighted to be involved in the JCB DIESELMAX project. The superior technology and reliability of E-T-A’s circuit breakers are well known to us. It was very important for this project that we could build a system using circuit breakers that were very resilient to shock and capable of resisting damaging ingress of salt and oil. For this reason we chose E-T-A type 483s, which we know are highly ‘spec’ed’ and well proven in motor sport and the aerospace industry, and we fitted them with standard dust covers.
The E-T-A 483 Circuit Breaker for Equipment (CBE) is a single pole temperature compensated thermal circuit breaker. Believed to be the smallest package on the market offering protection up to 35A, the range extends from 1A up to 35A. It features a push/pull on/off actuator with a tease-free, trip-free snap action mechanism. A high tolerance to sudden current surges is in-built, reducing the risk of nuisance operation, and enabling close matching of cable size to CBE. This avoids the common practice of overspecifying the cable size and using a higher rated fuse.
“Although the distribution panel was located behind a closed panel,” Millar continued, “it, nevertheless, was subject to inevitable exposure from fine salt particles and oil spray. We never had a single issue with the circuit breakers. One tripped just the once during the Bonneville runs, and that meant that that section of electrical harness was safely protected against the overcurrent that caused the trip.”
Andy Green, the fastest man on Earth, set the first-ever supersonic world land speed record at 763.035 mph in ThrustSSC on the Black Rock Desert on 15 October 1997. As he was feted by his jubilant crew on 23 August, Green said: “I am so pleased that we have got the car to 350mph which was always our ultimate goal and that was with a slow start to the second run. Today’s record proves the potential we have always believed JCB DIESELMAX to possess. This is another great result for a wonderful team and a testament to British engineering.”
"350mph is a fantastic speed for a diesel-powered car. To have built the world's fastest diesel in such a short timescale is a wonderful achievement for the JCB DIESELMAX team,” added Dr Tim Leverton, JCB’s Group Engineering Director and Project Director for the land speed record project. “What is even more impressive is to set three records – 317.021mph, 328.767mph (526.027 kph) and 350.092mph (563.418kph) in only six days.”
