2)
Measured at nominal voltage without coil suppression unit.
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.
