The Eaton 189896 is a high-quality 3-pole motor protection circuit breaker engineered to provide dependable control and safeguarding for electrical motors. This device is specifically designed to manage power loads up to 0.09kW, offering a precise adjustable thermal release range between 0.25A and 0.4A. By integrating both short-circuit and overload protection, it serves as a critical component in maintaining the integrity and operational safety of industrial and commercial electrical systems.

Advantages

This motor protection circuit breaker stands out for its robust construction and reliable performance in demanding environments. It effectively prevents motor damage caused by overloads or short circuits, thereby extending the service life of connected equipment. Its compact design allows for efficient space utilization within control panels, while the adjustable current range provides flexibility to match specific motor requirements, ensuring optimal protection settings for various applications.

Suitable for

• Industrial motor control systems
• Commercial HVAC equipment
• Small pump and fan motor protection
• Automated machinery and conveyor systems

This device may not be suitable for applications requiring higher power ratings exceeding 0.09kW or for motor circuits that demand a current range outside the 0.25-0.4A threshold. It is also not intended for use in environments with extreme moisture or corrosive gases unless housed in an appropriate protective enclosure.

Key specifications

• Number of poles: 3
• Power rating: 0.09kW
• Thermal release adjustment range: 0.25A to 0.4A
• Function: Short-circuit and overload protection

Installation should be performed by a qualified professional in accordance with local electrical regulations. The device is typically mounted on a standard DIN rail within an electrical distribution board. Once mounted, the thermal release must be calibrated to the specific full-load current of the motor being protected to ensure accurate tripping characteristics during fault conditions.

What to consider before purchase

• Verify the full-load current rating of your motor matches the 0.25-0.4A range.
• Ensure the power rating of 0.09kW is sufficient for your specific application.
• Check the available space in your control cabinet for mounting.
• Confirm compatibility with your existing electrical distribution system.

Usage recommendations

Regularly inspect the circuit breaker for signs of wear or thermal damage and perform periodic testing of the trip mechanism to ensure continued operational reliability.
