Draw-Out Device Installation

Figure 3. Right side of the device, showing the rejection feature, draw-

out position indicator, and electric operator cutoff switch.

Draw-Out Position Indicator

. Indicates whether the device is

in the connected, test, or disconnect position.
Electric Operator Cutoff Switch

. Prevents cycling of the spring-

charging motor during installation or removal of a device.
Draw-Out Interlock

. This feature trips a closed device if the

wrench interlock is deliberately defeated. The device is

tripped before the primary disconnects part as the device

is racked out and before the primary disconnects engage

as the device is racked in.
Rejection Feature

. This feature prevents insertion of a device

into a substructure of lower ampere rating or higher short-

circuit rating. It does not reject a device with incompatible

control wiring. See the label on the device or Tables 1 or 2

for the proper substructure catalog number. (Also shown

in Figure 8.)
Tables 3 and 4 illustrate the rejection scheme logic. Note

that devices may be safely used in higher-rated

substructures. However, local and industry codes and

standards require that conductors be sized to the

substructure. Therefore, installing devices in substructures

with higher ratings is possible, but not economical.
Draw-Out Padlock Accessory

. When a padlock is installed,

this feature works with the racking shaft lockout plate to

prevent engagement of the racking shaft wrench.
Shutter Actuator

. A stud actuates the optional shutter

accessory.
By-Pass Switch Actuator

Operates the optional by-pass

switch accessory.
Lifting Bar

. The Lifting Bar, catalog number TDOLB, is

available for safe handling of the draw-out device, as

illustrated in Figures 4 and 5.

Note: In the device catalog number, replace “X” with “B” for

MicroVersaTrip Plus™ or MicroVersaTrip PM™ Trip Units or

with “D” for Power+™ Trip Units
