The heater burnout current when there is a burnout at the load is as follows:
(Heater burnout detection current) = (17.3 + 10) / 2
= 13.65 [A]
To enable detection in either case, use 16.1 A as the heater burnout detection current.
(b) Star Connecting Lines
Example: Using Three 200-VAC, 2-kW Heaters
The current when each phase is normal is 5.8 A ( 10 A × (1 /3)).
The heater burnout detection current for this connecting line is 5.4 A (= (5.8 + 5) / 2).
