"increased safety" type of protection eex e according to atex directive 94/9/ec the 3ru11 thermal overload relays are suitable for the overload protection of explosion-proof motors with "increased safety" type of protection eex e. the relays meet the reuirements of en 60079-7 (electrical apparatus for areas subject to explosion hazards increased safety "e") see catalog ic 10. ec type test certificate for category (2) g/d exists. it has the number dmt 98 atex g 001. benefits the most important features and benefits of the 3ru11 thermal overload relays are listed in the overview table (see "general data" on page 5/42) . application industries the 3ru11 thermal overload relays are suitable for customers from all industries who want to guarantee optimum inverse-time delayed protection of their electrical loads (e. g. motors) under normal starting conditions (class 10). application the 3ru11 thermal overload relays have been designed for the protection of three-phase and single-phase ac and dc motors. if single-phase ac or dc loads are to be protected by the 3ru11 thermal overload relays, all three bimetal strips must be heated. for this purpose, all main current paths of the relay must be con- nected in series. ambient conditions the 3ru11 thermal overload relays have temperature compen- sation in accordance with iec 60947-4-1 for the temperature range of 20 c to +60 c. for temperatures from +60 c to +80 c the upper set value of the setting range must be reduced by the factor listed in the table below. accessories the following optional accessories are available for the 3ru11 thermal overload relays: for the four overload relay sizes s00 to s3 one terminal bracket each for stand-alone installation one mechanical reset module for all sizes one cable release for resetting devices which are difficult to access (for all sizes) one electrical remote reset module in three voltage variants for all sizes terminal covers 1 2 5 7 3 4 6 ambient temperature in c derating factor for the upper set value +60 1.0 +65 0.94 +70 0.87 +75 0.81 +80 0.73 lv1_2010_gesamtbuch.book seite 46 m ittwoch, 19. januar 2011 7:00 19 ? siemens ag 2011
