Motor Starter MMS-100S 75A – reliable motor protection

Motor starter MMS-100S is a key element in protecting electrical installations powering motors. The device is designed to effectively disconnect circuits in the event of overloads and short circuits, ensuring safe operation and extending the life of connected devices. The 75A model with an adjustment range of 55-75A is suitable for applications requiring solid protection for medium-power motors.

Functionality and application

Motor starters from the MMS-100S series are widely used in industry, construction, and commercial installations. They serve to protect electric motors from the effects of overloads, short circuits, and phase asymmetry. This minimizes the risk of failures, downtime, and costly repairs. The device's construction, based on LS ELECTRIC technology, guarantees reliable operation even in difficult operating conditions. Fixed mounting ensures stability and reliable operation for a long time.

• Overload protection: Smooth adjustment of the set current (55-75A) allows for precise adaptation to the load characteristics.
• Short-circuit protection: Fast reaction to a short circuit minimizes damage to the installation and connected devices.
• Application in various voltages: The ability to operate in the voltage range of 230-690V AC makes the starter universal and can be used in various power systems.
• Three-pole construction: Provides complete protection for three-phase asynchronous motors.
• Compliance with standards: It has a CE marking, confirming compliance with European safety standards.

Characteristics and construction

The MMS-100S starter is characterized by a solid construction and high quality of workmanship. The device has a protection class of IP20, which means protection against touching with a finger and against the ingress of solid objects larger than 12.5 mm. Made of durable materials, it ensures long-lasting and trouble-free operation. Screw connection provides a secure connection of wires, minimizing the risk of loosening connections during operation. The lack of an integrated undervoltage release and auxiliary contact allows for a simple construction and focus on the primary function – reliable motor protection. The manufacturer is the renowned company LS ELECTRIC Co., Ltd., which guarantees high product quality and access to technical service.
