Issue:
What are contacts T1, T2 used for on the VW3A7701 braking resistor?

Product Line:
VW3A7701 braking resistor

Environment:
VW3A7701

Cause:
Clarification of product features is needed by the customer

Resolution:
Contact T1, T2 are a thermally activated contact on the resistor to indicate an overheat condition of the resistor.  The contact are normally closed and open once the braking resistor temperature reaches 120 degrees Centigrade.  The minimum voltage/current for these contacts is 24VDC at .1 amps.  The maximum voltage/current is 250VAC at 1.0 amps.
