FEATURES

• High capacity

High capacity control possible at 22A/

31A (High capacity type) 250V AC rating

in compact size (L: 15.7 × W: 30.1 ×

H: 23.3 mm L: .618 × W: 1.185 × H: .917

inch)

• Contact gap: 1.5 mm .059 inch

Compliant with European photovoltaic

standard (VDE0126).

EN61810-1 certified: 2.5 kV surge

breakdown voltage (between contacts)

• 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.

• 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
