Technical support:

Refer to inside back cover.

Safe breaking, arc extinguished (normally open contact) for resistive loads.

Assumptions:

1. Thermal resistance = 50°C per watt

2. Still air

3. Nominal coil resistance

4. Maximum mean coil temperature = 180°C

5. Coil temperature rise due to load

= 2°C @ 8 amps

= 5°C @ 16 amps

= 11°C @ 24 amps

= 20°C @ 32 amps

= 32°C @ 40 amps

6. Thermal resistance and power dissipation

based on coil resistance at 180°C

7. Curves are based on 1.6 watts at 23°C

8. When full lifetime is at high ambient and high

load current, subtract 25°C from maximum

allowable ambient temperature.
