Motor starter, 3-phase, type MMS-32H with a range of 0.63-1A MMS-32H 1A

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

This three-phase motor starter from the MMS-32H series is a robust solution for protecting induction motors. Designed to operate in installations with a voltage of 690V, it effectively protects motors from the effects of overloads, short circuits, and phase asymmetry. Its compact dimensions (45 mm width, 105 mm height, and 90 mm depth) allow for easy installation even in tight spaces.

Functionality and Application

The MMS-32H starter is designed for switching motors with a rated current of up to 32A on and off. Thanks to the overload release setting range from 0.63 to 1A, this model is ideal for applications requiring precise adjustment to the load characteristics. The built-in magnetic release provides a quick response to sudden current surges, minimizing the risk of motor damage. Additional sensitivity to phase failure increases work safety and prevents malfunctions.

The MMS-32H series starters, thanks to the possibility of proper phase connection, can also be used to protect motors powered from a single-phase network – this is additional flexibility in application.

Construction and Characteristic Features

The device has a complete construction in an enclosure, which facilitates mounting and ensures durability. The knob serves as an actuator, allowing manual switching of the circuit on and off. The IP20 degree of protection guarantees protection against accidental contact and the ingress of solid objects larger than 12.5 mm. The built-in thermal protection protects against overheating, and the magnetic release method ensures a quick response to short circuits. The lack of an integrated auxiliary contact and undervoltage release allows you to adapt the functionality to specific application needs.
