Note: 1. The above values are initial values.
2. Rated and characteristic (initial) values are for a standard temperature of 23°C and a humidity of 65% unless otherwise indicated.
3. The contact resistance was measured with 10 mA at 1 VDC with a voltage drop method.
4. The insulation resistance was measured with a 500-VDC megohmmeter applied to the same parts as those used for checking the dielec-
tric strength.
