Application and Ratings

The Chance unitized D7 is a distribution-level, gang-operated, side-break switch for 15 through 

38 kV applications. It is pre-assembled, adjusted, and mounted on a common support at the 

factory for three-phase service. D7 switches meet a continuous-current rating of 600 amperes, 

a momentary rating of 40,000 amperes, a three-second short time current rating of 25,000 

amperes, and applicable NEMA and ANSI standards. It is available in 15 kV (110 kV LIW*), 

27 kV (150 kV LIW*), 34.5kV (150kV LIW*)  or 38 kV (200 kV LIW*). The D7 is a 600-ampere 

loadbreak switch with the Duogap

®

 expulsion interrupters. With the Duogap, the D7 is capable 

of switching load currents up to 600 amperes, with full recovery voltage across the switch, 

and interrupting transformer magnetizing and line-charging currents. This switch may be 

used for disconnecting, line sectionalizing, circuit breaker bypassing, and isolating.

*Lightning Impulse Withstand (BIL)

Convenient Installation

Field installation time of this pre-assembled switch is greatly reduced below what is usually 

required to install separate gang-operated distribution level switches. The three-phase unit is 

conveniently raised in one piece to its mounting position, secured to the pole, control sections 

attached, and field adjustment made. Proper synchronization and phase spacing have been 

made at the factory. Unitized switches are installed in 2 to 4 hours, compared to non-unitized 

switches that take 6 to 8 hours. 

One-lift  installation  cuts 

time  and  cost  of  separate 

gang-operated, distribution-

level switches.

Three mounting variations of the D7 are available.
