1. High switching capacity: 10 A 277V AC
2. High insulation resistance between
contact and coil
1) Creepage distance and clearances
between contact and coil: Min. 6 mm .236
inch
(In compliance with IEC65)
2) Surge withstand voltage between contact
and coil: 10,000 V or more
3. High noise immunity realized by the
card separation structure between con-
tact and coil
