This facility allows the ACB to be remotely operated locally.
The air circuit breaker is fitted with a removable umbilical connection that allows the operation of the circuit breaker from a safe area/distance.
Low voltage air circuit breakers (ACB) until recently have always been operated by personnel standing in front to the switchboard and using the mechanical push buttons located on the front of the ACB. In the event of an arc flash hazard event occurring this is a very dangerous place for the operator to be.
There are two solutions to this problem, one is for the operator to wear correct category PPE. Category 4 arc flash protection suit, depending on the energy levels present may not provide full protection. The other safer solution is to remove the operator from the dangerous area in front of the switchboard.
Terasaki have designed within the circuit breaker an umbilical connection socket which allows for a push button circuit breaker operation unit to be located at or outside the switch room door which can then be easily connected to the circuit breaker to be operated via an umbilical cable. Facility moves the operator from the dangerous location in front of the switchboard to a safe area. It also alleviates the need to run costly installation cables from a remote location to the switchboard.
A circuit breaker can either be supplied new or retrofitted into existing Terasaki circuit breakers.
Terasaki and Socomec Sicon hosted a Conference on the Future of Electrical Protection & Monitoring at Lord’s Cricket Ground on Thursday 6th February.
The conference provided an important forum for exchange between facility managers, industry professionals and academics, tackling the most critical global energy issues for our businesses. Dr. Catalina Sparatu from the Energy Institute at the University College London was the guest speaker and hosted a presentation on the Dynamic Simulation of Energy Systems.
Despite the Conference being held during the Tube Strike 50 delegates attended on the day and the event was judged to be a resounding success.
Over the past few decades the low voltage installation has become increasingly more challenging for Moulded Case Circuit Breakers (MCCBs). Increased fault levels, higher harmonics levels, changing legislation and demand for maximum uptime have substantially altered the requirements of this important protective device.
Our “Safe Switchgear Specification” Paper will update the professional electrical engineer on the safe application of low voltage MCCB technology and will examine thoroughly protection disciplines, isolation principles and future trends for MCCBs
The “Application of Circuit Breakers to Reduce Downtime in Datacentres” paper will describe circuit breaker selection methods and available circuit breaker technology which can contribute to reduced downtime in datacentres. It is divided into issues related to topology (or system layout) and sustainability (performance over time).
Find both articles on the MCCBs application notes’ page.
Amtech users now have the opportunity to design a complete protection system using Terasaki devices. Air Circuit Breakers (ACBs), Moulded Case Circuit Breakers (MCCBs) and Miniature Circuit Breakers (MCBs) covering 1A to 6300A ratings are included in the 2013 release.
Terasaki’s panelboard and distribution board ranges have been upgraded to include new TemBreak 2 Lite MCCBs and TD3 MCBs. Discrimination and cascade co-ordination between these devices is included in the software. Cascade protection of up to 40kA between MCCBs and MCBs has been proven by test.
Protection settings can even be uploaded and downloaded through the data link. This means that the settings can respond dynamically to changes in the electrical network (for example if the mains fails and the supply comes from a back-up generator). All the necessary protection relay models are included in Amtech software.
We also offer CIBSE CPD endorsed courses which have been used to train over 500 engineers in subjects such as discrimination and circuit breaker specifications. If you need training that is focused on learning, not selling, these concise courses are ideal.
Terasaki has published a new UK price list as a spreadsheet and as an indexed, searchable pdf file. It includes 220 pages of order codes and prices for circuit breakers, contactors, distribution boards and power factor correction. It is available to download from the website Download section.
A new version of up to date Order Codes List is also available on our Downloads page for our distributors.
Terasaki has extended the range of the popular TemBreak 2 MCCB range. New models have been developed from 800A to 1600A.
The 1000A model is be the same frame size as Terasaki’s existing XS800 (height = 273mm, width = 210mm, depth = 103mm). This is considerably smaller than most of Terasaki’s competitors who offer a 1600A frame device to protect 1000A circuits. Market prices of the new 1000A models are more competitive than the previous XS1250-CE / 1000A.
125kA and 200kA breakers in 800A frame are now available in the new range. Terasaki have recently won two large projects for Telehouse data centres by offering plug-in versions of the new 800A frame models.
The new MCCBs all feature from direct opening action to IEC 60947-5-1. This is a safety feature which is important for isolating machinery and is indicated by the direct opening action symbol on the nameplate. Only breakers made by Terasaki currently carry this safety mark.
Users can now benefit from the common design of TemBreak 2 MCCBs from 20A to 1600A. Shunt trips, auxiliary switches and alarm switches are exactly the same throughout the range and are easy to install in the field.
Terasaki’s two-dial electronic overcurrent relay also has the same design throughout the range, covering ratings from 20A to 1600A.
Terasaki Electric (Europe) Ltd in Glasgow have been supporting an apprentice programme for over twenty years now! Some of the first apprentices still work in the company.
At the moment we have six apprentices out of our 120 employees! One of them, Melissa Lyon, has been interview by Manufacturer Magazine recently, she has told about her experience in Terasaki.
Last September we had visitors from Chengdu Technicians College in China, who came to see how our apprentice programme works. The aim of the partnership was to introduce the Modern Apprenticeship model and work-based learning in general to our Chinese partners. In particular they were interested in Modern Apprenticeships in Engineering as this is the main focus of their College. The proposed outcome of the project has been to introduce an apprenticeship programme in mechanical engineering at their College as a pilot for further development of work based learning.
On the 17th-19th of February 2013 in Dubai Terasaki will take part in the Middle East Electricity exhibition in Dubai International Convention & Exhibition Centre.
