Motor starter, 3-phase, type MMS-32H with a range of 18-26A MMS-32H 26A

Motor starter for reliable motor protection

The MMS-32H motor starter with a setting range of 18-26A is a key element in protecting electrical installations powering three-phase motors. The device effectively protects induction motors against overloads, short circuits and phase imbalance, ensuring continuous operation and minimizing the risk of failure. The device's construction, based on thermomagnetic technology, guarantees a quick and precise response in emergency situations.

Construction and functionality

The MMS-32H starter is a complete device in a housing, designed for mounting on a 35mm DIN rail. Its compact dimensions (45 mm wide, 105 mm high and 90 mm deep) allow for easy integration with existing switchboards. The magnetic release mechanism provides an instantaneous response to sudden current increases, and the built-in thermal protection protects against the effects of prolonged overload. Additionally, the sensitivity to phase failure increases the safety of the installation. The knob serving as an actuator allows for easy operation and adjustment of operating parameters.

Application and benefits

This starter finds application in a wide range of industrial and commercial applications where reliable protection of electric motors is required. Thanks to the setting range of 18-26A, it will be ideal in circuits powering motors up to 11kW (at 400V). Using the MMS-32H starter translates to:

• Increased safety: Protection against overloads, short circuits and phase imbalance minimizes the risk of damage to the motor and electrical installation.
• Long-term reliability: Solid construction and precise operation of the release mechanism ensure a long service life of the device.
• Easy installation: Compact dimensions and the ability to mount on a standard DIN rail facilitate installation and integration with existing systems.
• Versatility: Can be used in three-phase (690V) power networks and – with appropriate phase connection – also single-phase.
• Phase failure protection: This function prevents damage to the motor caused by the absence of one of the supply phases.

The MMS-32H starter is an investment in the safety and reliability of your electrical installation, which will translate into reduced costs associated with downtime and repairs.
