N.B.
A low resistive suppression device in parallel to the relay coil increases the release time and reduces
the lifetime caused by increased erosion and/or higher risk of contact tack welding.

Assumptions:
1. Still air
2. Nominal coil resistance
3. Maximum mean coil temperature = 155 ˚C
4. Coil temperature rise due to load
= 8 °C at 10 A
= 20 °C at 15 A
35.5 °C at 20 A
5. Curves are based on nominal coil power at 23 °C
6. When full lifetime is at high ambient and high load current,
subtract 25 °C from maximum allowable ambient temperature.
