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: 5.5kW
• Thermal release range: 9-14A
• Function: Overload and short-circuit protection

To use the Eti-Polam MS18-9-14A, mount the device onto a standard DIN rail within a suitable distribution board. Connect the power supply and motor cables to the designated terminals, ensuring all connections are tightened to the manufacturer's torque specifications. Once installed, adjust the thermal release dial to the specific nominal current of the connected motor to ensure accurate protection.

What to consider before purchase

• Verify the nominal current of your motor matches the 9-14A range
• Ensure the power rating of 5.5kW is sufficient for your application
• Check available space in your electrical enclosure for DIN rail mounting

For optimal safety and performance, always ensure that the thermal release is calibrated correctly to the motor's full-load current and perform periodic inspections of the terminal connections to prevent overheating.
