LOVATO Electric SM1P1400 Motor Protection Circuit Breaker 9-14A 25kA 400V

The LOVATO Electric SM1P1400 is a robust motor protection circuit breaker engineered to provide reliable control and safety for electric motors in various industrial and commercial applications. This device is specifically designed to detect and interrupt electrical faults, ensuring the longevity and operational stability of connected equipment. With its precise thermal release mechanism and high breaking capacity, it serves as a critical component in modern electrical distribution systems.

Advantages

This motor protection circuit breaker offers exceptional reliability through its advanced thermal and magnetic trip units, which provide comprehensive protection against both overloads and short circuits. The manual push-button interface allows for intuitive operation and quick status identification, making it easy for technicians to manage motor control. Its compact design facilitates efficient use of space within electrical panels, while the high breaking capacity ensures safety even under demanding electrical conditions.

Suitable for

• Industrial motor control centers
• Commercial HVAC systems
• Pumping stations and irrigation equipment
• Conveyor belt systems
• Manufacturing machinery

When it may not be suitable

This device is not intended for use in circuits where the motor current falls outside the specified 9-14A range, as this would prevent proper thermal protection. It is also not suitable for high-voltage applications exceeding its rated operational voltage or in environments with extreme moisture or corrosive gases without appropriate protective enclosures.

Key specifications

• Adjustable thermal release range: 9-14A
• Breaking capacity: 25kA at 400V
• Operation type: Manual push-button
• Function: Overload and short-circuit protection

How to use

Installation should be performed by a qualified electrician in accordance with local electrical codes. The device is typically mounted on a standard DIN rail within a control cabinet. Once mounted, the motor leads are connected to the terminals, and the thermal release is adjusted to the specific full-load current of the motor. The push-button mechanism allows for manual switching and provides a clear indication of the breaker status.

What to consider before purchase

• Verify that the motor full-load current falls within the 9-14A range.
• Ensure the supply voltage matches the 400V rating.
• Check the available space in your electrical enclosure for DIN rail mounting.
• Confirm that the short-circuit current of your system does not exceed 25kA.

Usage recommendations

Regularly inspect the terminals for tightness and ensure the push-button mechanism operates smoothly. Periodically test the trip function to maintain optimal safety standards in your electrical installation.
