As to "types" of contactors, in what context? Construction? Application? Voltage? Duty cycle?

NEMA contactors are much heavier duty than IEC contactors rated the same. They also tend to cost about 3X more than IEC. They are also larger than IEC. They tend to take more abuse than IEC. The theory is that if you've invested in these expensive NEMA contactors you will be rewarded by long life and the ability to repair them as you can order all the various bits when they wear out. The reality of it is that it's very hard to figure out the part numbers needed to order the various bits and then finding someone who has them to sell you. About half the time you end up with the wrong parts that cost a serious percentage of the price of the original contactor. It may be well less expensive to just replace an entire IEC contactor that has an issue than the time and cost required to fix a NEMA contactor.
