Section 8—ComPacT NS1600b–NS3200 Circuit Breaker

ComPacT NS1600b–NS3200

The ComPacT NS1600b–NS3200 circuit breakers feature the exclusive MicroLogic electronic trip units, which allow for a range of sophisticated applications for metering and monitoring. In addition, trip units can be interchanged in the field to allow for maximum flexibility.

The compact size and smaller footprint of the NS circuit breaker permits higher density installations. These circuit breakers are available in up to 3200 A construction to meet a broad range of commercial and industrial application needs.

• Circuit breakers are available in 3200 A construction with a sensor size range of 600–3200 A.

• Interrupting ratings (AIR):

• The N interrupting rating is recommended for applications having high inrush and/or non-linear loads such as large motors, transformers, motors with soft starts, etc.

• ComPacT circuit breaker size allows for smaller footprint installations. Fifteen-inch width provides increased density installation.

• Most field-installable accessories are common to all frame sizes for easier stocking and installation.

• Selection of four interchangeable MicroLogic trip units available, with PowerLogic power metering and monitoring capabilities available in advanced trip units.

• Compatible with PowerLogic systems and high amperage power circuit breakers.

• Built-in Modbus protocol provides an open communications platform and eliminates the need to purchase additional, proprietary network solutions.

• Connection options include bus or cable for installation flexibility.

NS1600b–NS3200 circuit breakers are equipped for bus connection only. For certain amperages, an RLTBE terminal pad kit may be required. (Same kit as the PowerPacT R-frame circuit breaker.) Refer to PowerPacT R-Frame Termination Information for terminal pad kit information.

Accessories are available either factory-installed or field-installable. They can be installed in accessory compartments behind the circuit breaker accessory cover. (Same accessories as the R-frame circuit breaker.)

Control wiring is connected to terminals located under the circuit breaker accessory cover.

Refer to Wiring Diagrams PowerPacT R-Frame Control Wiring. (Same as the R-frame circuit breaker.)
