It would take someone to get one and try to install it 'first' to see if it fits. Secondly, the 11.1% reduction in the contact rating would steer ME away from installing this if it even fit. The contacts of a 45 amp relay are burning up, why would you install something with that 11.1% reduction in the current rating? All I can say is have fun, but get a number of them because you'll (in my opinion) be replacing them a lot more often.
