Wiring Notes

Observe the following notes when wiring the breaker for
operation:
posi-
• Customer-supplied contacts (such as
) should be momentary action, rated for 0.25

A at 125 Vdc for dc motor operators or rated for 3 A
at 120 Vac for ac motor operators.
• Do not apply power to any terminal board point
other than points 1 and 2.
• Observe the proper polarity for dc motor operators
(point 1 is positive).
• When performing hi-pot or dielectric tests:
– Remove all power leads, both control and power.
– Short all motor operator terminal board points.
– Open the circuit breaker.
– Test between the motor operator terminal board
points and the load side of the breaker's center
pole (this pole is connected to the frame).
– Test at 2200 Vac for one minute using a current-
limited, nondestructive ac hi-pot tester with
maximum output of 20 mA.
