Motor starter, 3-phase, type MMS-32H with a range of 1-1.6A MMS-32H 1,6A

Motor starter MMS-32H is a reliable protection for 3-phase motors. The device, manufactured by LS Electric, effectively protects induction motors against the effects of short circuits, overloads and phase imbalance. Its compact dimensions – 45 mm width, 105 mm height and 90 mm depth – facilitate installation even in tight spaces.

Protection and application

The MMS-32H circuit breaker with a setting range of 1-1.6A is designed for switching on and protecting motors with a rated current of up to 32A. Thanks to its phase failure sensitivity, it provides additional protection against damage resulting from the loss of one of the supply phases. The use of a magnetic trip unit guarantees a quick response in the event of a short circuit, and the thermal one protects against overloads. The possibility of using it to protect motors powered from a single-phase network (with appropriate phase connection) increases its versatility.

Construction and characteristic features

The device has a solid construction – it is a complete device in a housing, which facilitates installation and ensures durability. The degree of protection IP20 means that it is protected against touching with a finger and against the ingress of solid objects larger than 12.5 mm. The knob allows for convenient adjustment of the overload trip unit setting in the range of 1 to 1.6A. The lack of an integrated auxiliary contact and undervoltage release allows you to adapt the functionality to specific application needs. The rated operating voltage is 690V, which makes it suitable for a wide range of industrial installations.
