overload relay

[hounddog05]

im hooking up a new motor starter. on the electronic overload relay there is the following termination points....A1, A2, normally closed 95 and 96, normally open 97 and 98. I got control voltage to the motor contactor, does the overload relay also need its own control voltage (120vac) landed on its own A1 and A2 points?

Who is the manufacturer ?

If whatever is sending signal to coil is maintained contact, go in to 95 and out from 96 on way to coil.

Or in other words break line from switch thru normally closed on it's way to coil.

If I could draw with keyboard like others can I would.

sw---95/96---A1

(A2 not shown, neutral or other leg powering coil, aka common).

Yes, some electronic OL relays need their own source of control power to power up the internal electronics, but some are self powered by the CTs when the current flows through.

Sometimes the A1 A2 terminals on the OL relay are just extensions of the A1 A2 terminals of the contactor coil, because if you stab the OL relay into it, it ends up covering up the coil terminals.

If you post a name and number, we can likely help you better.

A1 and A2 is usually the contactor coil terminal designations, like jraef said it may just be extensions from the contactor coil.
