Motor starter, 3-phase, type MMS-32H with a range of 14-22A MMS-32H 22A

Three-phase motor starter MMS-32H – reliable motor protection

This three-phase MMS-32H motor starter is a key element in protecting induction motors. It provides effective protection against overloads, short circuits, and phase imbalance, which translates to a longer lifespan and trouble-free operation of devices. The design with a rotary actuator ensures convenient use and reliable operation.

Functionality and application

The MMS-32H starter is designed to switch on and protect motors with a nominal current of up to 32A. The ability to also use it to protect motors powered from a single-phase network (with appropriate phase connection) increases its versatility. Thanks to its sensitivity to phase failure, it protects the motor from damage caused by the absence of one of the supply phases. The built-in thermal release reacts to overheating, and the magnetic release immediately disconnects the circuit in the event of a short circuit.

Key features and benefits

• Versatile application: ideal for 3-phase induction motors, and also – with appropriate connection – for single-phase motors.
• Complete protection: protection against overload, short circuit and phase imbalance.
• Phase failure sensitivity: additional safety for the motor in case of power supply problems.
• Simple operation: a knob for adjusting and switching the starter on/off provides intuitive operation.
• Solid construction: a complete device in a housing with dimensions of 45 x 105 x 90 mm ensures durability and resistance to mechanical damage.
• Setting range: Smooth adjustment of the overload release range in the range of 14-22A allows for precise adaptation to the load characteristics.
• Compliance with standards: meets the required safety standards (IP20).

The MMS-32H starter is characterized by a rated continuous current of 22A, and the setting range of the overload release is from 14 to 22A. It operates at a rated voltage of 690 V and has 3 poles. The degree of protection IP20 provides basic protection against contact and ingress of solid objects. The release method is magnetic, which guarantees a quick response in the event of a short circuit.

The MMS-32H starter is a proven choice for both professional installers and end-users looking for a reliable solution to protect their motors. Its solid construction and functionality guarantee safe and efficient operation for a long time.
