Cut-off temperature is measured with silicone oil bath of which temperature is increased at the rate of 1° per minute. Detecting current is 0.1A or less.
Th and Tc are for C-UL(CSA) and CCC respectively.

Features
t is a high performance thermal cutoff/ resistor assembly which combine a cement resistor with a fusible alloy type thermal cutoff and has an overheat protect function.
It uses coil-winding for greater ability to withstand inrush current.
It can open the circuit certainly in the case of any circuit malfunction. Its characteristics rarely fluctuate.
It provides extremely robust electrical insulation and voltage withstanding properties after it functioned, and almost no trouble occurs with residual resistance or re-continuity.
It does not contain lead (Pb) and cadmium (Cd) in compliance with RoHS.
It does not contain 46 substances of very high concern (SVHC) that are specified by REACH as of Dec. 2010.
