When switching a resistive (DC1) or inductive (DC13) load having voltage and current values under the corresponding curve, an electrical life of > 30000 cycles can be expected. 

**NOTE:** The heating and electrical endurance tests have been performed on relays soldered on PC boards having the following characteristics: double side, copper thickness >105 μm, contact tracks width 40 to 45 mm, total cross section about 10 mm[2]

## **Energy saving mode** 

In some applications, such as photovoltaic inverters, it may be necessary to minimize the overall relay power dissipation and to permit use at higher ambient temperature levels (up to 85 °C). This can be achieved by initially applying a coil voltage within the Energy saving mode Operating range (see diagram to the left) and then rapidly (< 1 s) reducing the coil voltage to a level within the Holding voltage range. The lower the Holding voltage, the lower is the continuous power dissipation of the coil (0.7 W minimum). 

Coil voltages as high as 2.5 UN may be used, when necessary, to reduce the contact operate time. 

**1 -** Max. permitted coil voltage. 

**2 -** Min. pick-up voltage with coil at ambient temperature.
