Motor Starter MMS-32S – Reliable Motor Protection

The MMS-32S motor starter is a key element in protecting electric motors from overloads, short circuits, and phase imbalance. This device, manufactured by LS Electric, is widely used in automation control circuits and electrical systems, ensuring their stable and safe operation. This model is characterized by a solid construction and high reliability, making it an ideal choice for both professional installers and end-users.

Functionality and Application

The MMS-32S starter is designed to work with three-phase motors with a voltage of 400V and a power of up to 0.06 kW. Its main task is to protect the motor from damage caused by overload or short circuit. It has three normally open poles, which ensures effective disconnection of the circuit in case of a failure. Additionally, the thermal-magnetic trip with a reset button allows for quick restoration of power after removing the cause of the trip. The magnetic trip current is 3.3A, providing a quick response to sudden current surges.

Construction Features and Mounting

The MMS-32S starter has been designed for easy mounting on a DIN rail. Its compact dimensions (75 mm depth, 45 mm width, 94 mm height) allow for installation even in limited space. The device weighs only 0.32 kg, making it easy to transport and install. The IP20 degree of protection provides basic protection against accidental contact and the ingress of solid objects. The use of normally open main contacts guarantees a reliable disconnection of the circuit in case of protection activation. Adjustment of the thermal protection in the range of 0.16...0.25A allows for precise adaptation to the characteristics of the protected motor. Mechanical and electrical endurance at the level of 100,000 cycles ensures long-term and trouble-free operation of the device.
