Motor starter switch MMS-32S - current 8A MMS-32S 8A

Motor starter MMS-32S is a reliable device designed to protect electric motors from overloads and short circuits. It is a key element in power supply installations for motors, ensuring their safe and efficient operation. The starter is based on a thermal-magnetic principle, meaning it combines thermal protection (against overload) and magnetic protection (against short circuit).

This model, with a rated current of 8A, is used in circuits with operating voltages from 230V to 690V AC. The rated short-circuit breaking capacity at 400V AC is as high as 100kA, guaranteeing effective protection even in the event of serious disturbances in the network. The starter features a three-pole design and has an adjustable overload release range from 5A to 8A. This allows for precise adjustment to the load characteristics.

MMS-32S is not only protection but also convenient installation and use. The device is designed for mounting on a 35mm DIN rail and has a protection degree of IP20, ensuring safety under normal operating conditions. Additionally, the possibility of mounting additional auxiliary contacts (e.g., LX) expands the functionality of the starter, allowing integration with control and signaling systems. This allows installers to easily integrate it with existing industrial automation systems.

Construction features and application:

• Motor starter MMS-32S has been designed to provide comprehensive protection for electric motors.
• The use of characteristic C allows for a slower response to short current surges, which is particularly important when starting motors with high inrush current – this prevents unnecessary tripping of the device.
• Phase failure protection increases the safety of the installation and minimizes the risk of motor damage in the event of a missing phase.
• The ability to connect additional auxiliary contact blocks allows for expanding the functionality of the starter and integration with control systems.
• These starters are compatible with various busbar systems (Phase Bus System), which facilitates the construction of compact and efficient switchgear.
• Compliance with IEC 60947-1 and UL508 standards ensures a high level of safety and reliability of the device.

Motor starters of the MMS series are widely used in various industries, including: construction machinery, industrial equipment, HVAC systems, and applications related to industrial automation. Their solid construction and high quality of workmanship guarantee long-lasting and trouble-free operation even in harsh environmental conditions.
