Occasionally someone raises the question of maximum traction motor
current. Circuit breaker CB 1 is in the armature circuit. If these
are marked as circuit breaker are usually marked, that is, the current
rating is stamped on the end of the reset button, then the E 20 has
a 50 A breaker and the E 15 a 40 A breaker. Now 50 A times 36 V yields
1800 W or 2.4 HP.
Does this seem reasonable in terms of the performance of the E 20 or
other tractors in the line-up?
