Ideal unit for E-T-A 8345 hot-swappable CBEs in telecomms and other industrial applications

E-T-A Circuit Breakers has introduced a new, compact, modular power distribution system suitable for rack mounting to handle currents up to 125A per channel. When populated with E-T-A circuit breakers, it facilitates rapid start-up and re-configuration of complex systems without downtime.

The E-T-A X8345-D01 Power Distribution System is a 2U-height rail system designed for fitting into 19"/23" or ETSI racks. Its modular design allows customer-specific and economic configurations in telecommunications and transport industries, for power supplies, switchgear, instrumentation and process control applications. It accepts the plug-in E-T-A type 8345 circuit breakers which can be specified to handle from 0.05A up to 125A each and which offer group signalisation. A complete X8345-D01 module will handle 600A in total. Systems can be extended or re-configured without powering down as X8345 circuit breakers are hot-swappable. Live parts in the plug-in area of the load terminals are protected against brush contact to IP20. 

In combination with the toggle switch, hydraulic-magnetic type X8345 circuit breakers, the X8345-D01 rack is ideal for telecommunications control cabinets. They provide a comprehensive power distribution system to protect wireless or wireline equipment, whether for switching technology, transfer mode systems, network access technology or mobile radio systems.

The E-T-A 8345 magnetic circuit breaker for equipment (CBE) is a fully approved circuit breaker for telecommunications equipment, plant control systems, the rail industry and other applications where reliable protection in a compact package is essential. The 125A maximum rating is 25A higher than the industry norm, allowing designers to increase power output without consuming valuable rack space. The product is fully approved to UL489, UL1077 and EN 60934, requiring the circuit breaker to be fit for purpose after interrupting a short circuit at its maximum specified fault rating. Thus, an extra measure of protection for expensive electrical equipment is assured, reducing costly downtime caused by power interruption.

E-T-A offers a wide range of power distribution systems, racks and circuit protection solutions for the telecommunications industry, as well as offering racks or sub-assemblies, wired and pre-fitted with circuit breakers, electronic power controllers and other components customised to meet specific requirements.

These products are highlighted in a new 20-page brochure ‘E-T-A Communication’, available free from E-T-A at http://www.e-t-a.com/uk_literature1.html.  This covers products used in exchange and transmission technology as well as mobile telephone base stations. It emphasises the complete system solutions and explains the advantages of E-T-A circuit breakers, including their space saving, the ability to ‘hot swap’, and the local/remote re-set capability. Along with descriptions of 20 products it also lists their typical applications.

Achilles Link-Up Scheme enables supply and overhaul of electrical components, general enclosures and electrical/electronic equipment (including modules).

E-T-A Circuit Breakers, designer and manufacturer of a broad range of electro-mechanical and electronic products for circuit protection, switching and control, is pleased to announce its recent inclusion in the Achilles Link-Up Qualification Scheme. Link-up is the UK rail industry supplier qualification scheme, providing a single common registration, qualification and audit process for suppliers.

E-T-A Circuit Breakers has met all the demanding criteria required by the Achilles Link-Up Qualification Scheme in order to be included to supply and overhaul electrical components, general enclosures and electrical/electronic equipment, including modules. The qualification scheme supported by Network Rail and over 80 other Rail companies in the UK is an initiative implemented to comply with the EU Utilities Directive, Group Standards (including GM/RT2450) and the EU Utilities Directive (where this is applicable), and to support the Supplier Development Policies of Rail Companies who subscribe to the scheme. More information can be found at www.achilles.com/uk/transport/ 

E-T-A manufactures a range of products suitable for the rail industry for refurbishment projects and for new applications in surface and underground rolling stock. These include the versatile 3120-F7 rocker switches with integral, precision circuit breakers. These attractive, ergonomically-styled products are ideal for passenger use, for example for the frequent on-off switching of lights and heaters, at the same time providing accurate overcurrent protection. The fully approved E-T-A 8345-DC110V circuit breaker is believed to be the only product of its kind which is backed up with full test data for 110V DC usage with the highest fume classification. It can be used in F0 locations in passenger carriages. The product is backed by full test data to international standards to withstand vibration, shock, corrosion, humidity and 5000A rupture capacity at 110V DC.

E-T-A Circuit Breakers designs and manufactures a broad range of electro-mechanical and electronic components and sub-systems for circuit protection, control and instrumentation, including the world’s largest programme of circuit breakers for equipment (CBEs). Alongside examples of systems solutions, the company will be showcasing electronic circuit breakers for the protection of circuits in factory automation systems, as well as flow meters and level sensors for the process industry.  

The E-T-A ESS20 electronic circuit breaker selectively protects individual output circuits from switch-mode power supplies (SMPS). It provides advanced circuit protection for loads such as sensors, actuators, field bus couplers and controls. In combination with an E-T-A power distribution system, Module 17plus or SVS02, the ESS20 offers optimum utilisation of cabinet space, as well as minimising wiring and reducing installation and maintenance costs.

The company offers CBEs with current ratings from 50mA up to 500A. Activation mechanisms include thermal, thermal magnetic, magnetic and magnetic hydraulic. They include high performance products for aircraft, and specialised circuit protection devices for buses, trucks, workboats and pleasure boats. In addition to a wide range of standard products, many of which can themselves be adapted to specific requirements, E-T-A specialises in providing customised solutions. This is a complete service extending from design and prototyping through to full production of sub-systems such as 19" subracks, fully populated and pre-wired with plug-in CBEs. These solutions may be anything, from simple brackets and bus bars to more complex assemblies built and supplied ready to fit and forget. As circuit protection specialists, E-T-A has the expertise and in-depth knowledge of its products to ensure that the most suitable ones are chosen to optimise the design and produce the most cost-effective solution.
