1. High sensitivity: 250mW
The power-saving relay is highly sensitive
at the nominal operating power of 250
mW (530 mW power consumption on LK
relays).
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 con-
tact and coil: 10,000 V or more
