Trying to acquire multiple cutler hammer circuit breakers that are somewhat difficult to find. The older models are still reliable. With the right frame and housing it should trip when a surge is detected. So the question is can I trust this manufacturer? Westinghouse also makes quality breakers as well. I just want to make sure all the equipment is protected properly. I was thinking of purchasing four as a backup to keep them on hand in case we need them in a hurry.
