hello phillipd, The asked component (contact element) 3SB3400-x has itself no B10/B10d value, because this component can’t work without an actuator. If using this contact element, then is always too an actuator needed (contact block work not alone). But the actuator itself has of course, different to the contact element3SB3400-x, a B10 value if this component is a safety relevant part with positively driven contacts, e.g. emergency stop (3SB3000-1HA20),. For the actuator is a standard B10 value available which is listed into the following documentations. In the following attached letter “Customer_letter_B10_01-06-2011.pdf” the B10 values of our control devices are listed.This custom letter contents:- An example for the calculation of the dangerous failure rates with B10 values (= at electromechanical components and switching cycles) according the EN62061 and- A table with the SIRIUS standard B10 values of electromechanical componentsThe B10 values are listed too in ourCatalog IC 10issue 2011 on chapter13 page 13 and14 link http://www.automation.siemens.com/ce-static/ftp/e86060-k1010-a101-a1-7600.pdf (sorry actually only German version available)Into the SI 10 N 2012 catalog chapter 5 page 3 are too further B10 values for safety relevant components listed and additional the dependence of the B10 values and the utilization categories. The SI 10 N 2012 catalog is available via link http://www.automation.siemens.com/mcms/infocenter/dokumentencenter/ce/Documentsu20Catalogs/e86060-k7010-a121-a1-7600.pdfFurther information’s you find in our brochure “Safety Integrated Functional Safety of Machines and Systems Convenient Implementation of the European Machinery Directive “Link to download the brochure: http://www.automation.siemens.com/mcms/infocenter/dokumentencenter/ce/Documentsu20Brochures/e20001-a230-m103-v5-7600.pdfIn this brochure you will find: - on page 19 a glossary. - on page 18 a table with standard-B10-values and percentage of dangerous failures for the electromechanical range of SIRIUS products. - on page 16 the transfer from B10 and percentage ratio of dangerous failures into SIL resp. PL. Further interesting information, hints and FAQs can be obtained The calculation of the B10d value is according the formula B10 divided through the Ratio of dangerous failures.
