Motor starter, 3-phase, type MMS-32H with a range of 0.25-0.4A MMS-32H 0,4A

3-Phase Motor Starter Switch MMS-32H – Reliable Motor Protection

This MMS-32H motor starter switch is a key element in protecting 3-phase induction motors. Designed to operate in the range of 0.25-0.4A, it effectively protects motors from the effects of short circuits, overloads, and phase asymmetry. This is a complete device in a housing, ready for installation and providing comprehensive protection.

Construction and application

The MMS-32H switch is characterized by a solid construction and a precise magnetic tripping mechanism. The rotary actuator provides convenient and reliable operation. The device is ideal for industrial applications where reliability and safety are a priority. The possibility of using it to protect motors powered from a 1P network with appropriate phase connection increases its versatility.

• Thermal protection: The integrated thermal overload relay protects the motor from the effects of prolonged overload, preventing overheating and damage.
• Phase failure sensitivity: Phase failure detection function protects the motor from operating in incorrect conditions that can lead to serious failures.
• Magnetic tripping: Fast magnetic tripping reacts immediately to short circuits, cutting off the power and minimizing the risk of damage to the motor and electrical installation.
• IP20 protection class: Provides basic protection against contact and ingress of solid objects, which is important in industrial environments.

Technical parameters and dimensions

The MMS-32H switch has compact dimensions – 45 mm width, 105 mm height, and 75 mm depth – making it easy to install even in tight spaces. The rated operating voltage is 690...690 V, making it compatible with most standard electrical installations. The knob is used to adjust the setting of the overload trip release in the range of 0.25...0.4 A, allowing you to tailor the protection to the specific needs of the application.
