Certified by CSA

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.

Dimensions
	Features It is a high performance thermal cutoff/ resistor assembly which combine two coil-winding resistors with a fusible alloy type thermal cutoff and has an overheat protect function. It realizes reducing the mounting space and decreasing the number of components. It uses a coil-winding for greater ability to withstand inrush current. It will open the circuit certainly in the case of any circuit malfunction. Its characteristics will 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. Because the marking is printed on the topside, it is easy to confirm the products after assembling. 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.
