Calorific value of the circuit breaker

How to calculate the calorific value of the circuit breaker?
Category : 


1. The internal resistance (per pole) is described in the catalog and technical notes.
2. Power consumption (W) = RI^2 x Poles = Resistance (Ω) x Load current (A) ^2 x  Number of poles (P)
3. Calorific value (J) = Power (W) × Time (s)
<Note>The internal resistance is representative value, and is not guaranteed value.
