## Long description

The LOVATO Electric SM1R0400 is a professional-grade motor protection circuit breaker engineered to provide precise control and robust protection for electric motors in various industrial and commercial environments. This device is specifically designed to safeguard electrical systems by monitoring current levels and interrupting the circuit in the event of an overload or short circuit, thereby preventing potential damage to connected equipment.
Advantages
This motor protection circuit breaker offers exceptional reliability due to its high breaking capacity of 100kA, which ensures safe operation even under severe fault conditions. The adjustable thermal release range allows for fine-tuned protection tailored to the specific requirements of the motor, while the integrated rotary handle provides a user-friendly and secure method for manual switching and status indication. Its compact design facilitates efficient use of space within electrical control panels.
Suitable for
Industrial motor control centers
Commercial HVAC systems
Pump and compressor protection
Conveyor belt motor management
Automation and control panels
This device may not be suitable for applications requiring current ratings outside the 2.5-4A range or for environments where the operating voltage significantly exceeds the 400V specification. It is also not intended for use in high-moisture or corrosive atmospheres without appropriate protective enclosure housing.
Key specifications
Thermal release adjustment range: 2.5-4A
Rated operational voltage: 400V
Breaking capacity: 100kA
Control mechanism: Rotary handle
Function: Overload and short-circuit protection
To use the LOVATO Electric SM1R0400, mount the device onto a standard DIN rail within a suitable electrical enclosure. Connect the incoming power supply to the top terminals and the motor leads to the bottom terminals, ensuring all connections are tightened to the manufacturer's specified torque. Once installed, set the thermal release dial to the rated current of the motor being protected. The rotary handle allows for manual switching of the motor on and off, and it will automatically trip to the neutral position in the event of a fault.
What to consider before purchase
Verify the full load current of your motor falls within the 2.5-4A range
Ensure the system voltage matches the 400V rating
Confirm the available space in your control cabinet for DIN rail mounting
Check compatibility with existing electrical distribution standards
Usage recommendations
Always ensure that the power supply is disconnected before performing any installation or maintenance work. Regularly inspect the terminals for tightness and check the device for signs of wear or damage to maintain optimal protection levels.
