I'm looking for a surge protector and have two in mind:
P6B
Surge energy rating 490 Joules
eP Joule Rating 465
P74
Surge energy rating 490 Joules
eP Joule Rating 1080
The eP Joule Rating for the P74 is much higher than that of the P6B. Can someone please tell me the difference between eP Joule Rating and Surge Energy Rating?
thanks in advance

That is correct.
The main difference between our Surge Protectors and our competitors, is that we do not rely on Joule ratings alone. APC Surge Devices shunt the excess voltage that come through with a surge, while competitors simply absorb the excess voltage.
The higher the Joule rating the better the surge absorbtion, but APC uses absorbing as a last line of defense. If the Surge Protector is not plugged into a grounded outlet, then the only line of defense will be absorbing the surge, and it will not perform to its full capabilities.
Thanks.

Basically what it means is the P74 passed our surge testing with better marks than the P6B, as compared to our competitors' surge protectors.

Thanks for your response;
On what scale? So this means that the higher the eP Joule rating the better the product?
