The Cleaveland/Price DB-A is a three pole, group operated, aluminum double end break switch used primarily in substations. It is available at 345 kV, 2000A through 5000A.
The double side break design is useful in applications where there is limited overhead clearance and interphase distances need to be kept at a minimum. The switch is ideal for EHV applications where a naturally counterbalanced blade is advantageous.
Reference the DB-AV tab for drawings of the switch in a “V” configuration for low profile mounting.

DB-CV “V” Copper Double Break
The DB-CV uses the same current carrying parts as the DB-C, however, the jaw end insulators are inclined. By having the jaw end insulators inclined, the cable conductors establish electrical clearance from the base without the need for wire guides or outriggers. The inclined insulator design makes the switch suitable for low profile substations. This design is available from 115 kV through 161 kV.
The Cleaveland/Price DB-C is a three pole, group operated, copper double end break switch used primarily in substations. The switch is available in a “V” configuration at 115 kV to 161 kV. The double side break design is useful in applications where there is limited overhead clearance and interphase distances need to be kept at a minimum. Because the blades of the switch will not be energized when the switch is in the open position, the switch can be installed on the same phase spacing as a vertical break switch.

Group Operated Switch Overview
Cleaveland/Price offers many group operated switch types including vertical break, center break, double end break and single end break. All of the switches are available with copper current carrying parts. The switches are typically supplied as three pole switches for substation, transmission, and distribution applications. The switches can be mounted in the horizontal-upright, vertical, horizontal-underhung, or inclined position.
The switches are suitable for use in a variety of applications including line disconnecting and sectionalizing, circuit breaker by-pass and isolation, and transformer isolation. Arc horns or quick break whips are available when small amounts of transformer magnetizing currents or line charging currents must be interrupted.
Full load break attachments are available for vertical break switches. Accessories needed to adapt the switch to a customer’s particular requirements are available.
The switch may be manually operated by use of a swing handle or wormgear mechanism or electrically operated by use of a Cleaveland/Price TP-C2 motor operator.
Cleaveland/Price’s switches meet ANSI C37, NEMA, and IEEE Standards and the rating requirements of IEC Standards.
