I regret to inform you that the 40A breaker you already have to have in circuit is going to trip faster than that PTC, in 0.8-1.8 seconds.

This is the datasheet for the Snap Action breaker in the 2012 KOP.
http://www.snapaction.net/pdf/MX5%20Spec%20Sheet.pdf
150 % overload = 3.9 - 47 seconds
175 % overload = 2.2 - 9.2 seconds
200 % overload = 1.5 - 3.9 seconds
250 % overload = 0.8 - 1.8 seconds
300 % overload = 0.5 - 1.1 seconds
400 % overload = 0.3 - 0.6 seconds
500 % overload = 0.2 - 0.3 seconds
Correct?
