The overload protection setting range (Ir) for the Eaton NZM2-ME200-NA is adjustable from 100A to 200A.
This breaker is specifically designed for motor protection. While it can be used in power distribution systems, its features and settings are optimized for motor circuits and may require specific integration considerations.
This refers to the adjustable time delay setting. It means the breaker will delay tripping for 2 to 20 seconds when subjected to a current that is 6 times the set overload current (Ir), allowing for motor startup inrush.
The breaker measures 105mm (width) x 149mm (height) x 195mm (depth).
It uses a screw-in method for the main circuit connection.
This is a 3-pole breaker, designed for three-phase motor applications. For single-phase motors, a different configuration or breaker type would typically be required.
It is approved to UL/CSA and IEC regulations.
Verify motor's full load current and adjust the overload setting (Ir) to be at least 10% higher. Check time delay (tr) setting; it may need to be increased to accommodate motor inrush current.
Ensure the overload setting (Ir) is correctly configured below the motor's expected overload current. Check for loose connections within the breaker or circuit.
Identify and resolve the cause of the trip (overload, short circuit). Ensure the reset mechanism is fully engaged. If the issue persists, the breaker may require replacement.
Check terminal connections for tightness and ensure appropriate cable size is used. Clean any corrosion from terminals.
Setup: The NZM2 breaker connects via a screw-in method for the main circuit. Ensure all connections are secure and torqued to the manufacturer's specifications. The overload release (Ir) and time delay (tr) settings should be adjusted based on the motor's nameplate data and application requirements before energizing the circuit. Consult the product manual for detailed wiring diagrams and setting recommendations.
Compatibility: This breaker is part of the NZM..-ME..NA series and is suitable for motor circuit protection, often used in conjunction with contactors. It is approved for use in applications compliant with IEC and UL/CSA regulations. Verify compatibility with your specific control panel design and system voltage.
Care: To ensure optimal performance and longevity, regularly inspect the breaker for any signs of damage or wear. Keep the unit clean and free from dust and debris. Periodic checks of electrical connections are recommended to ensure they remain tight. No internal maintenance is typically required for the electronic components, but external cleaning should be done with a dry or slightly damp cloth; avoid solvents.
