Components and Accessories

EvoPacT MV circuit breakers move on side-mounted rollers supported on rails inside the cell. Circuit breakers can roll on bottom-mounted wheels outside the cell.

Circuit Breaker Compartment, 1200 A and 2000 A

These are mounted in a one- or two-high structure, and auxiliary devices can be mounted above a circuit breaker in a single high structure. Instruments can be mounted on the door in front of the circuit breaker.

Doors are standard left-hand hinged and come with two thumb screws per door. Doors are also available with a latching system. Please see your sales representative for more information. Through-door racking is standard on the circuit breaker. For details on through-door indicator position see Instruction Bulletin NNZ9886800.

• Mounted on left-hand side above each circuit breaker in the circuit breaker compartment 25–40 kA

• Operates in the Test and Connected Positions as standard

• 10 contacts as standard, 13 contacts available

• Rated to 10,000 Cycles.

• Mounted on right-hand side above each circuit breaker in the circuit breaker compartment up to 25 and 40 kA

• Auxiliary Contacts same as MOC

• 10 contacts as standard

• Rated to 1,000 Cycles

CTs are front-accessible, bushing/window-type, 600 V rated, single- or multi-ratio CTs can be mounted in the compartment around the insulating tubes of the line or load-side primary high-voltage contact bushing assembly. A maximum of four CTs, depending on accuracy, can be mounted per phase—two on the line side and two on the load side.

• 1 or 2 standard-accuracy CTs on line and/or load side or

• 1 high-accuracy CT on one side, plus 1 or 2 standard-accuracy CTs on the other.

Please reach out to your Schneider Electric representative for more information.

Voltage Transformer Details

• Customers can select up to three 5 kV or 15 kV VTs. For increased space savings, LPVTs (Low Power Voltage Transformers) are also available and are mounted behind the LV box. See LPVT Application Sheet or reach out to your Schneider Representative for more details.

5/15KV SureSeT Voltage Transformers

Control Power Transformer Details

• 5, 10, or 15 kVA single-phase CPTs are available.

• The secondary circuit breaker on the drawout truck is mechanically interlocked.

• Padlock provision is standard

Low Power Voltage Transformers

Low Power Voltage Transformers are voltage sensors based on resistor dividers for low power digital protection and measuring devices, LPVT provide a low voltage output signal compatible with the new generation of digital relays and secondary equipment with high input impedance.

Due to its reduced size and weight, it brings an easy installation compared with standard VT and allows to have bigger instrument compartments because of the removal of the traditional VT drawer solutions.

Benefits of LPVTS include:

• Insensitive to core saturation due to over-voltages and ferroresonance free due to lack of magnetic cores

• No issues for short-circuits on secondary side.

• Can support the protection function 25 - Synchronizing or Synchronism-Check Device.

• No need of MV fuses

• Cost saving solution during planning and execution due to the ability to serve a wider range of applications with fewer models. This leads to easier specification and design for consultants and reduces required inventory for integrators, resulting in potentially shorter lead times for end users.

• The same product reference can guarantee both metering and protection purpose with a wide operating voltage range.

Application Details

A quantity of 3 for each cubicle that requires LPVTs shall be used and connected phase to ground. Each LPVT is provided with a shielded RJ45 cable.

1 x LPVT HUB EMS59573 is required in all cubicles featuring LPVTs and it shall be mounted in the LV box, the signals coming from the 3 LPVTs are merged into this HUB.

In case the required protection relay/meter/voltage sensing device does not feature a LPVTs input option, the transducer P7M12025 is required to connect the LPVTs to the device voltage inputs. A power supply is required for this transducer and shall be UL Listed Class 2 or an Industrial Control Low Voltage Limited Energy Power Supply

 LPVT and standard VT cradle/drawers cannot be used in the same line-up.

See LPVT application and specification sheet for more details E85875.

CPT Drawout

• 5, 10 or 15kVA single phase CPT are available.

• The secondary breaker on the drawout truck is mechanically interlocked.

• Padlock provision is standard.

• For CPT and Fuse Selectrion see E58400.

• For CPT specificatons see E85115.

For Seismic Applications, CPTS must be mounted on the floor in the lower compartment.

Breaker Test Cabinets

An optional test cabinet is available. The test cabinet consists of a small metal enclosure including:

• A power on-off selector switch.

• An amber light indicating the power is on.

• A red light indicating the circuit breaker is closed.

• A green light indicating the circuit breaker is open.

• Close and open push buttons.

• An 8 ft. (2.44 m) cable with a secondary control receptacle that can be plugged directly into the EvoPacT circuit breaker top secondary control plug.

Test cabinet can be wall-mounted as shown. Refer to documentation provided with test cabinet for mounting and electrical diagrams.
