2.Perfect for small load switching of home appliances

105switching operations possible with a 3A 250V AC resistive load.

mminch 3. Low operating power

Compact size, nominal operating power as low as 200mW.

4. High shock resistance

The relay withstands a functional shock resistance of 300m/s2 [approx. 30 G more]

5. High insulation resistance

•Creepage distance and clearances between contact and coil: Min. 6 mm .236 inch(In compliance with IEC65)

•Surge withstand voltage between contact and coil: 10,000 V or more.

6. UL/CSA, VDE, TÜV approved.
