Are the LAD703F coils rated for continuous duty?

Issue:
Continuous duty on a LAD703F.

Product line:
Tesys D IEC Contactors and Overload Accessories

Environment:
LAD703 remote stop or electrical reset
LA7D03 remote tripping or electrical reset

Cause:
Customer was using competitor brand and it burns after 10 seconds

Resolution:
The time for which the coil of the remote tripping or electrical resetting device, LAD703 or LA7D03 can remain energized depends on the rest time in between energizing the coil.
Minimum pulse to energize is 200ms

1 second pulse needs a 9 second rest time
5 second pulse needs a 30 second rest time
10 second pulse needs a 90 second rest time
Maximum duration of energizing the coil is 20 seconds and would require a 300 second rest time.
