Technical Terms
  • Rated Functioning Temperature (Tf)
    The acceptable tolerance is +0,-10°C

  • Holding Temperature (C-UL&CSA:Th, CCC:Tc)
    The maximum temperature at which the thermal cutoffs may be maintained.

  • Maximum Temperature Limit (Tm)
    The maximum temperature at which an opened thermal cutoff does not reclose.

Notice: Please read Standard Specification and Instruction Manual for details of use.
