Introduction to EvoPacT

The Square D™ brand EvoPacT medium voltage vacuum circuit breaker is a drawout (removable) device enabling switching and assists in the protection of distribution networks. Installed in medium voltage switchgear used up to 15 kV, it provides up to 40 kA short circuit interrupting capability protecting downstream conductors and limiting the electrical and mechanical stress to components situated downstream. The specific rating of each circuit breaker is printed on the circuit breaker nameplate. The EvoPacT medium voltage circuit breaker is a horizontal drawout circuit breaker designed for use with medium voltage metal-clad switchgear.

Surge Protection for EvoPacT Circuit Breakers (Statement of Use)

Circuits in which these circuit breakers are placed are capable of producing overvoltages. The following general guidelines will address the vast majority of application concerns. However, they do not guarantee complete system protection from the occurrence of overvoltages.

• Complex medium voltage systems may require a detailed overvoltage system analysis and the addition of an RC network.

• All circuits should have at least distribution class arresters unless cable lengths exceed 300 ft. (91.5 m). In many cases, external arresters are already used for other reasons. Surge protection is not provided as standard equipment, but is an available option (as necessary per customer specifications).

• For dry-type (including cast-resin type) transformers and motor loads, surge capacitors should be used at the terminals of the transformer or motor. Where there are long lengths of cable, the cable capacitance may offer surge capacitor protection if the cable capacitance is equivalent to typical values available in surge capacitors.

The nameplate shown here is only to be used as an example and does not reflect actual values that will be stated on the customer specific circuit breaker nameplate. The customer’s specific circuit breaker ratings and all required information will be shown on the nameplate of the circuit breaker. The nameplate label also shows information on the motors and auxiliary control units installed on the device, and their operating voltages. The nameplate label is placed near the center of the circuit breaker front cover.

The serial number (SN) located on the nameplate is using 18 characters in order to be easy to understand. Example: SE-2016-W44-5-0018.

To access to Safe Repository, enter the serial number with its simplified 11 characters’ format. Example: SE164450018.

If the long description is typed in, it will be automatically converted to the short description. The QR code link implement the simplified format.

The QR code, located on the nameplate, grants access from a smartphone or a connected tablet to all data relating to the specific circuit breaker including:

• serial number

The serial number and the commercial reference number also allow access to the information without a smartphone or connected tablet.

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E, NOM-029-STPS,  CSA Z462, or local equivalent. Observe all circuit breaker installation, operation, and usage instructions. Never operate the circuit breaker if it is damaged. Do not allow the ambient operating temperatures to exceed the specified limits. The ambient operating air must not be significantly polluted by dust, particulates, smoke, corrosive and/or flammable gases, vapors, or salt. Failure to follow these instructions will result in death or serious injury.

The circuit breaker, including its auxiliary and control circuits, is designed to operate according to its rated characteristics and the service conditions below:

If operated beyond the normal service conditions, the circuit breaker is submitted to accelerated aging.

The circuit breaker may only be used under conditions other than the normal service conditions with express written permission from Schneider Electric.
