Lovato Electric SM1R0650 Motor Protection Circuit Breaker 4-6.5A 100kA 400V

The Lovato Electric SM1R0650 is a robust motor protection circuit breaker engineered to provide reliable control and comprehensive protection for electric motors in various industrial and commercial environments. This device is specifically designed to safeguard electrical systems by detecting and interrupting overloads and short circuits, thereby preventing potential damage to connected equipment. Featuring a high breaking capacity of 100kA at 400V, it ensures operational stability even under demanding electrical conditions.

Advantages

This circuit breaker offers exceptional reliability through its precise thermal release mechanism, which is adjustable within the 4-6.5A range to suit specific motor requirements. The inclusion of a rotary handle allows for intuitive manual operation, providing users with clear status indication and easy control. Its compact design facilitates efficient space utilization within control panels, while the high short-circuit breaking capacity ensures that the device can handle significant fault currents, maintaining safety and continuity in complex electrical installations.

Suitable for

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

When it may not be suitable

This device is not intended for use in circuits where the motor current falls outside the specified 4-6.5A adjustment range. It is also not suitable for applications requiring remote electronic monitoring or communication capabilities, as it is designed primarily for manual operation and local protection.

Key specifications

• Thermal release adjustment range: 4-6.5A
• Breaking capacity: 100kA at 400V
• Operation type: Rotary handle
• Protection function: Overload and short-circuit protection
• Mounting: Standard DIN rail or screw mounting

How to use

The device should be installed by a qualified professional within a suitable electrical enclosure. Once mounted, the thermal release current should be set to the nominal current of the motor using the adjustment dial on the front panel. The rotary handle allows for manual switching of the motor circuit. In the event of a trip, the handle will move to a neutral or trip position, allowing for easy identification of the fault before resetting the device.

What to consider before purchase

• Verify that the motor nominal current falls within the 4-6.5A range.
• Ensure the supply voltage matches the 400V rating.
• Check the available space in your control cabinet for installation.
• Confirm that the short-circuit current of your installation does not exceed 100kA.

Usage recommendations

Regularly inspect the device for signs of wear or thermal damage and perform periodic testing of the trip mechanism to ensure continued protection of your electrical assets.
