Description
The Hubbell unitized Type AR switch is a distribution-level, loadbreak, gang-operated side-break switch designed to meet not only today’s needs but well into utilities’ future of distribution automation. Designed for nominal system voltages of 14.4kV and 25kV three- and four-wire systems and 34.5kV grounded-wye systems. The Type AR switch is available with a variety of options, and in ratings for present and planned requirements.
To minimize eld installation time, the Type AR switch is pre-assembled, adjusted and mounted on a crossarm. Instal­lation time is even faster for a Type AR switch with the hook stick-operation option.

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 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 eld 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, distribution­level switches.

DesignFeatures
The jaw socket and hinge terminal castings of the D7 are bronze with tin-plated NEMA terminal pads. The blade is a round tubular copper with attened ends to allow for a silver/copper contact. A four-point silver plated contact is supplied on the jaw end to make the switch easier to open and close. An all-copper current path is provided.
Interrupters
Chance Duogap® expulsion interrupter converts any D7 to a loadbreak switch. Built-in sockets on each switch accept the interrupter. The
Chance 15.5, 27 and 38 kV Duogap expulsion interrupters .
Duogap may be ordered with the switch or may be hotstick-installed for load management conversion. For more on the Duogap, see Bulletin No. 14-9405.
Terminal Pads, Arcing Horns
Two-hole NEMA terminal pads are standard. The D7 terminal pads are bronze with tin-plating to provide low-resistance efcient current transfer.
14A-11
A stainless steel arcing horn is provided to pick up load current, thus preventing burning or arc pitting on the main contacts.
Insulators
The Vee conguration of the insulators simulates a low prole with less bulk and a pleasing visual appearance. The gray-tone insulator for the unitized D7 switch is NEMA 3-inch BC.
15 thru 34.5 kV Switch Base and Bearings
The base castings consist of high strength, high corrosion resistant aluminum alloy. This lightweight aluminum is comparable to bronze in almost all metal technical categories, such as: ultimate tensile, tensile yield, elongation, hardness, modulus of elasticity, thermal conductivity, and electrical conductivity. Bearings are high-strength, high-density Delrin, for smooth pivotal action.
Conductors are dead-ended to each individual switch base. Pull-off holes are designed for a 6,000-lb. working load rating. The switch frame is limited to an unequal loading of 700 lb.
Common Support
The 4 x 4-inch common support member is furnished in either galva­nized-steel or berglass tubing. The “interphase” shaft which connects the three rotating insulators is constructed of the same material as the crossarm.
Controls
Controls are either all metal or metal with a vertical berglass section. Three options combine the metal or insulated interphase shaft with the metal or berglass common support.
The arcing horn will pick up load current upon closing to prevent burning or arc pitting on the main contact surfaces.
