The Form 6 recloser control can be used with the old-style
Type A CTs; however, the event recorder and duty cycle
monitor will have limited accuracy for currents above 5000
Amps.
Retrofit kits with the new Type B sensing CTs are
available to upgrade existing families of reclosers for
operation with Form 6 recloser controls. For additional
information, contact your Cooper Power Systems
representative.
For identification, Table 1 lists the serial number breaks
between old-style Type A and the new-style Type B sensing
CTs. Below this serial number, the recloser is equipped
with the Type A CTs.
Note: For reclosers shipped prior to June 1989 and not listed
below, please contact your Cooper Power Systems
representative with the recloser type and serial number
for verification of type A or B bushing current
transformers.
Duty Cycle Monitor
The Duty Cycle Monitor provides the following duty cycle
information:
• Measures and records duty for each individual phase in
non-volatile memory.
• The recloser duty is measured and stored on the basis
of Current
1.5
x Number of Operations for Each Phase
(ANSI C37.61).
• Readout is based on a percentage of total duty cycle
for each phase.
• Duty record can be adjusted or reset if recloser is
changed-out, serviced, etc.
Using Table 2, select the appropriate recloser interrupting
duty cycle factor and enter that value via the ProView
interface software.
Mounting the Control
Mount the Form 6 pole-mount recloser control in a
convenient, accessible location. Mounting dimensions are
provided in Figure 10.
Note: Unless otherwise specified, dimensions shown in mm
(inches).
A hole and keyway in the control mounting bracket accom-
modates a 15.9 mm (5/8”) bolt.
Locking the Control
The handles on the Form 6 control cabinet are able to
accept a padlock to prevent unauthorized access. For
cabinets with the quarter-turn latch, the top handle has two
locking holes provided depending on the diameter of the
lock shackle being used. Refer to Figure 10.
• Use the smaller hole for shackle diameters of .177-
295”.
• Use the larger hole for shackle diameters of .295-.394”.
Note: DO NOT use a smaller shackle (.177-.295) in the
larger diameter hole as it will NOT LOCK the cabinet.
