L: .618  W: 1.185  H: .917 inch

• Contact gap: 1.5 mm .059 inch and

1.8 mm*** .071 inch

Compliant with European photovoltaic

standard (IEC62109* and VDE0126**).

*Safety standard of PV power inverter

**German safety standard of PV power inverter

***Due to addition of altitude stipulation (2,000 m

6,561.68 ft or more) to IEC62109.

EN61810-1 certified: 2.5 kV surge

breakdown voltage (between contacts)

• High insulation resistance

Creepage distance between contact

and coil terminal: Min. 9.5 mm .354 inch

Clearance distance between contact

and coil terminal: Min. 6.5 mm .256 inch

Surge breakdown voltage: 6 kV

• Coil holding voltage contributes to

saving energy of equipment

The coil holding voltage can be reduced

up to 35%V of the nominal coil voltage

(Ambient temperature: 20C 68F).

Power consumption at the lowest coil

holding voltage: 170 mW equivalent

*Coil holding voltage is the coil voltage

after 100 ms from the applied nominal

coil voltage.

*When the ambient temperature during

use is 85C 185F, make the coil

holding voltage between 45% and

80%V of the nominal coil voltage.

• Conforms to various safety

standards

UL, C-UL and VDE approved
