 Surface-Mounting Thermostate ATHs-70U 
  Temperature Range: +20°C to +150°C
   Works as Safety Temperature Limiter with Manual Reset.
   Versions according to EN VDE-Specifications.
   The Safety temperature Limiter for many application areas. 
     
 
   Technical Description
   
   Operation 
   The operation of the surfacemounting
   thermostat relies upon phenomenon of 
   liquida expansion. The volume of a 
   liquid filled sensor system (consisting of 
   sensor, capillary tubing and membrane) 
   varies with varying temperatures. 
   The resulting membrane displacement 
   actuates the mirco-switch.
   The temperature is only sensed by 
   the temperature sensor.  
   
   Switching Operation
   When the actual temperature exceeds 
   limit temperature the mircoswitch 
   opens (or closes) the 
   electric ciruit by the sensor system.

   Change Over Contact
   When the limit temperature is 
   exceeded, the electric ciruit is 
   opend (or closed) and the 
   mircoswitch is mechanically locked. 
   After the temperature has returned 
   down to the set limit the 
   mirocswitch can be unlocked 
   manually, only. 

   Switch Element
   Cased miroswitch with
   change over contact and 
   lock-out facillity.
   Opening (or closing) only 
   upon rising temperature.

  TÜV certifies for compilance with 
   DIN 3440 standards,
   system of protection IP54 (cased).

   Application Area
   The ATHs-70U surface mounting thermostat is 
   used as a safety temperature limiter in 
   laboratory and climatic cabinets, in 
   furnace applications and
   in mechanical applications per DIN 3440 standard.

   Safety Temperature Limiter
   with:
   change over contact and lock-out. 
   Reset button can be operated after 
   removing the cap. 
   Adjustable Temperature Range: +20°C to +150°C

   Note:
   per DIN 57100 part 420 VDE0100 
   are two temerature momitoring systems, 
   independent from each other, forcing required. 
   One of them has to be performed as 
   safety temperature limiter.
