Thermoswitch (T/C oil) Apply an ohmmeter between the terminal and body and check for continuity (resistance value). Replace the thermoswitch if the measured insulation resistance value is not more than the value listed in the table below.
1 M ohm or more (with contact OFF) (at 500 V megger)
Insulation resistance value
Internal resistance: 0.5 ohm or less (with contact ON) Allowable load: 0.5 A
NOTE When installing the thermoswitch, tighten it to the specified torque.
31.4 to 47.1 N·m (3.2 to 4.8 kgf·m) [23.2 to 34.7 lbf·ft]
Replace the thermoswitch if it was dropped or abused.
Main specifications OFF→ON
122 ± 3 °C (251.6 ± 5.4 °F)
115 °C (239 °F) or higher
Insulation resistance (with contact OFF)
1 M ohm or more
