Functioning Temperature
- The temperature at which the thermal cutoff opens (fuses off) while passing 0.1 amp. or less in a controlled oil bath at arise of 1℃ per minute. The functioning temperature is not the Rated Functioning Temperature.
-
-
-
Holding Temperature (Th)
-
The highest temperature of the thermal cutoffs at which it does not open the circuit while passing rated current for 168 hours.
(Applicable to UL, cUL and CCC)
-
-
-
Maximum Temperature Limit (Tm)
- The highest temperature of the thermal cutoffs at which continuity does not occur for 10 minutes after the function of the thermal cutoff.
-
-
-
Maximum Use Temperature
- The highest temperature of the thermal cutoff at which it does not function or the functioning temperature does not become higher remarkably after being exposed for certain amount of time.
-
-
-
Rated Current (Ir)
- The allowable maximum current which the thermal cutoffs is able to carry.
-
-
-
Rated Functioning Temperature
-
Rating of the functioning temperature based on safety standards. Tolerance of rated functioning temperature is +0, -10℃ for IEC 60691. Tolerance for METI is ±7℃ except some types.
ELCUT Thermal cutoffs are rated to satisfy those requirements.
-
-
-
Rated Voltage (Ur or Vr)
- The allowable maximum voltage which can be applied to the thermal cutoff.
-
-
-
Thermal cutoff
- Thermal cutoff is a safety device which open circuits against overheat. It detects the heat caused by the over-current due to short circuit or component breakdown.
