TUSS – WIRE CONNECTED – for domestic and industrial water heating applications

This product is part of ROD/STEM THERMOSTATS
Relevant applications:


1-pole temperature regulation and 1-pole safety limiter



  • Independent non self resetting safety function
  • Over temperature cut out
  • Available with single pole limiter or as control only
  • Factory pre-set fixed temperature limiter, OEM adjustable or end-user adjustable control temperature
  • Wire connected


The differential expansion of the sensing element causes the opening of a snap-action switch in the thermostat head.  In case of abnormal temperature rise, a bimetal disc ensures double pole safety.  The limiter is manually re-settable.
