hazardous voltage. Solidly ground all equipment. failure 

to comply can result in death, severe personal injury, 

and equipment damage. 

t223.2

4.  Ground the recloser. Make ground connections to the 

recloser ground connector. For substation installations, 

the ground connector is moved to the bottom of one 

of the extension legs, as shown in Figure 10. It will 

accommodate 2/0 to 250 MCM stranded conductors. 

Make ground connections in accordance with approved 

utility standards.

The VSA recloser is used with a control. Refer to the 

appropriate service information manual for complete 

recommended grounding instructions for the control.

5.  Install the control. Connect the control cable between 

the control and the recloser. Make sure the control is 

grounded and properly programmed for the planned 

installation.

6.  Make the high-voltage line connections. See Figure 3.

Disconnect switches and bypass switches are recom-

mended to facilitate switching and isolation.

A.  Surge protection on both sides of the recloser is 

recommended. However, if protection is provided 

on only one side, it should be located on the source 

side for line installation and on the load side for 

substation installation.

B.   Connect high-voltage lines to recloser bushing 

terminals. VSA12, VSA12B, VSA16, and VSA20 

bushing terminals are universal clamp-type and 

will accommodate conductors ranging in size from 

4/0 to 1000 MCM inclusive. VSA20A bushings are 

equipped with 1 1/4 - 12 UNF-2A threaded studs.

to facilitate maintenance and with complete surge 

protection.

7.  Block ground sensing via the control panel.
8.  Close source and load disconnect switches.
9.  Closer reclosers via control signal.
10.  Open bypass switches.
11.  Enable ground sensing, if applicable.

Heaters

Cabinet heaters are provided in both the operating 

mechanism cabinet and at the bottom of the interrupter 

enclosure cabinet. Power is supplied to both sets of heaters 

from the 240 Vac source and are connected through a 

DPST toggle switch and 2 A fuses, see Figure 5. The two 

mechanism cabinet heating resistors are rated 500 Ω, 50 

W; the two interrupter enclosure heating resistors are rated 

1000 Ω, 100 W.

Form 3 and Form 3A electronic controls must be equipped 

with the KA1175ME fuse accessory. This accessory 

supplies a MDQ-2.5 closing coil control fuse, which is 

required for operation of the closing solenoid.

The instantaneous reclose delay plug must not be used in 

Form 3 and Form 3A controls. For fast reclosing, use the 

KA1177ME1 reclose delay plug, which provides a fixed 0.5 

second delay.

VSA12, VSA12B, and VSA16 reclosers use 1000:1 ratio 

current sensing transformers (CTs), VSA20 and VSA20A 

reclosers use 2000:1 ratio CTs. Form 3 and Form 3A 

controls, used with 1000:1 CTs, require 

yEllow

 labeled 

trip resistors; 

BluE

 labeled trip resistors are required with 

2000:1 CTs. Refer to S280-75-1 for additional information.

All microprocessor controls must be programmed for the 

appropriate CT ratio.
