Motor starter, 3-phase, type MMS-32H with a range of 2.5-4A MMS-32H 4A

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

This three-phase motor starter of the MMS-32H type is a key element in protecting induction motors. Designed for operation in installations with a voltage of 690V, it effectively protects motors against overloads, short circuits and phase imbalance. Its construction, based on a mechanical rotary drive, ensures reliable and fast operation.

Functionality and application

The MMS-32H starter with a setting range of 2.5-4A is ideal for protecting motors with a nominal current of up to 32A. The possibility of using it in single-phase networks (with appropriate phase connection) increases its versatility. Using the starter in the installation ensures not only the safety of the motor's operation, but also minimizes the risk of downtime caused by failures.

• Thermal protection: a built-in thermal release protects the motor against overload, preventing it from overheating and damage.
• Magnetic protection: fast magnetic tripping reacts to sudden current surges, protecting against the effects of short circuits.
• Phase failure sensitivity: phase failure detection function prevents the motor from operating in incorrect conditions, which extends its lifespan.
• Solid construction: a complete device in a housing with dimensions of 45 x 105 x 90 mm ensures durability and resistance to environmental conditions (IP20).
• Simple installation: the current setting knob makes it easy to configure the starter to specific application needs.

Key features and benefits

The MMS-32H starter is not only a protective element, but also a convenient tool for installers and end-users. Thanks to the precise setting range (2.5-4A), it can be adapted to the specifics of the protected motor. High quality workmanship guarantees long-lasting and trouble-free operation of the device, which translates into savings related to repairs and replacements. Additionally, the possibility of use in single-phase networks increases the flexibility of the installation and allows for optimal use of resources.
