This question probably has more power behind it than usual here, but this is the best place I could think of to ask.
I'm looking to locate a contactor for use in running a 2HP 220VAC motor. I'm not entirely sure of which specs to look at. I know about the coil voltage, the HP rating, the current and voltage ratings; are there any others I should watch for?
Being a 220VAC circuit, there is no neutral wire, just two hot lines. The contactors I have located (such as Telemecanique LC1D12BL) are either for 1 or 3 hot wires, not two. Is there a problem only using two of the three? Some contactors, such as this one, come with an auxilliary contact. Can I use the third contactor connection as a second auxilliary contact for another low voltage circuit?
