When it may not be suitable

This device is not intended for use in circuits exceeding its rated current of 0.25A, as it will cause nuisance tripping or fail to provide the necessary protection. It is also not suitable for applications requiring more than two poles or for environments with extreme environmental conditions that exceed the manufacturer's specified operating temperature and ingress protection ratings.

Key specifications

• Rated current: 0.25A
• Number of poles: 2
• Function: Overload and short-circuit protection
• Application: Motor protection

How to use

The EATON Z-MS-0,25/2 should be installed by a qualified electrician in accordance with local electrical regulations. The device is typically mounted on a standard DIN rail within an enclosure. Ensure that the supply voltage is disconnected before beginning installation. Connect the incoming power lines to the input terminals and the motor supply lines to the output terminals, ensuring all connections are tightened to the specified torque. Once installed, the device can be manually switched to the on position to energize the motor circuit.

What to consider before purchase

• Verify that the motor's full-load current matches the 0.25A rating of the device.
• Ensure the installation environment is compatible with the device's physical dimensions and mounting requirements.
• Confirm that a 2-pole configuration is sufficient for your specific electrical circuit design.

Usage recommendations

Regularly inspect the circuit breaker for signs of wear or thermal damage. Test the tripping mechanism periodically to ensure the device remains functional and capable of protecting the connected motor equipment during an electrical fault.
