LS DA-16SD GMD + MMS-32S Mini Contactor and Motor Circuit Breaker Assembly

The LS DA-16SD GMD + MMS-32S is a compact, integrated assembly combining a mini contactor and a motor circuit breaker. This unit is engineered for the reliable control and protection of industrial electric motors, offering a streamlined solution for motor starter applications. By integrating switching capabilities with thermal-magnetic protection, it ensures that motors operate efficiently while being shielded from electrical faults.

Advantages

This assembly provides a space-saving design that simplifies installation within electrical control panels. By combining the contactor and circuit breaker into a single unit, it reduces wiring complexity and minimizes the footprint required for motor control systems. The robust construction ensures long-term reliability in demanding industrial environments, providing consistent performance for motor switching and protection against operational hazards.

Suitable for

• Industrial motor control systems
• Motor starter applications
• Protection against motor overloads
• Short-circuit protection in electrical circuits

This unit may not be suitable for applications requiring high-power motor control beyond the specified thermal and magnetic ratings. It is also not intended for use in environments with extreme moisture or corrosive atmospheres unless housed in an appropriate protective enclosure.

Key specifications

• Integrated mini contactor and motor circuit breaker
• Thermal-magnetic protection mechanism
• Compact assembly design
• Designed for industrial motor starter applications

How to use

The assembly should be mounted on a standard DIN rail within a control cabinet. Ensure that the power supply is disconnected before wiring the input and output terminals according to the electrical diagram. Once installed, the motor circuit breaker should be calibrated to the rated current of the connected motor to ensure proper overload protection. After verifying all connections, the system can be energized and controlled via the contactor coil.

What to consider before purchase

• Verify the motor's rated current matches the breaker's adjustment range
• Ensure the control voltage for the contactor coil is compatible with your system
• Check available space in the control panel for the assembly dimensions
• Confirm the environmental conditions meet the manufacturer's operating requirements

Usage recommendations

Regularly inspect the electrical connections for tightness and ensure the motor circuit breaker is tested periodically to maintain optimal safety and performance standards.
