The new standard allows users and specifiers to pertinently define the requirements of each application.

InGoogle was founded, the first Apple iMac was introduced and the legendary Windows 98 was released by Microsoft. The BS EN standard specifies that specific margins must be added to the 6149, when using anything other than type testing. In this case the test value is set at operations. Upon completion of the above, and moving into production, the standard requires routine verification be carried out by the Control Panel Manufacturer to ensure continued compliance to the design verified solution is met.

It states that the capabilities of each assembly will be verified in two stages: Learn more about the cookies we use and how to change your settings.

Annex D of the BS EN standard provides a list of 13 categories or verifications required, what testing method can be used and what comparisons can be made. This website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3.

The major change introduced by the new BS EN standard refers to testing.

een Under the old BS EN specification customers would demand a Type Test certificate for each assembly particularly Incoming Air Circuit Breakers, which was very expensive and time consuming. The OEM is responsible for the basic design verification. Accept and continue Learn more about the cookies we use and how to change your settings.

The standard gives details on the requirements of these products through testing and other verification methods. Find Similar Items This product falls into the following categories. This means the new standard completely discards the type-tested TTA and partially type-tested assemblies PTTA categories in favour of design verification.

BS EN Low-voltage switchgear and controlgear assemblies. General rules

To ensure JME are fully certified to manufacture electrical control panels to the new In addition, the assembly manufacturer is meant to oversee the completion of the assembly and routine testing.

You may experience issues viewing this site in Internet Explorer 9, 10 or The new standard recognises that several parties may be involved between concept and delivery of a switchboard assembly. Customers who bought this product also bought BS EN Switchgear and Control Gear assemblies are multifaceted and have an endless number of component combinations. Terminals for external conductors This, again, be the onus on the panel builder to ensure that the contractor will be able to terminate his cables on to the switchboard.

Temperature Rise One of the biggest areas of change in the standard revolves around this area.

Dividing responsibility A second major change implemented by the new industry standard refers to the responsibilities of each party involved in the design, test and implementation of low voltage switchboard assemblies. The options include using an already verified design for reference, calculation and 611439.

Changing Industry Standards: BS EN One Year On

Although BS EN still regards type testing as the preferred option for verifying designs, it also introduces a series of alternative routes to design verification. Before the introduction of the new standard, testing every conceivable variant was not only time consuming and costly, but impractical. IEC is the International Electrotechnical Commission standard which covers low voltage switchgear and controlgear assemblies.

Search all products by. In order to optimise testing time, the standard allows derivation of the rating of similar variants without testing, assuming the ratings of critical variants have been established by test.

BS EN 61439

The faster, easier way to work with standards. In a market where 6139 demand to optimise and reduce costs blends heavily with higher needs for assembly flexibility, the introduction of a new set of standards was needed to guarantee the performance of Low Voltage Switchgear Assemblies.
