Notes:
    (1) SF109E contains Cadmium and is not RoHS Compliant.
    (2) Part numbers are for standard lead devices. For long leads, add the number "-1" at the end of the part number.
    (3) TM,Tm for SF188E, SF214E, SF226E and SF240E are as follows:

    November 2005: please see Tm upgrade letter
      VDE UL CSA BEAB CCC
    SF188E 375 °C 300 °C
    SF214E 375 °C 350 °C
    SF226E 300 °C 240 °C 330 °C 300 °C
    SF240E 375 °C 350 °C

    (4) The electrical ratings by safety standards are as follows:

    Rated Voltage UL CSA VDE BEAB CCC PSE
    AC120V
    15A (Inductive)
    15A (Resistive)

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.
