fixed facilities. The surge voltage withstand level for up to the rated voltage of 300 V is 2500 V.
*3 This index indicates the degree to which conductive material is generated in terms of the environment in which the equipment is used.
Pollution level 2 is when only non-conductive pollution occurs. A temporary conductivity caused by condensing must be expected
occasionally.
