Motor starter MPE25-2.5 004648007

Motor starter – reliable motor protection

This three-pole MPE25-2.5 motor starter is a key element in protecting electrical installations powering motors. It provides comprehensive protection against overload and short circuit, minimizing the risk of damage and downtime. Its design, based on the thermomagnetic principle, guarantees a quick and effective response in emergency situations.

This starter is designed to operate in networks with a rated voltage of 400 to 690 V, and its rated continuous current is 2.5 A. The ability to adjust the overload release setting range (1.6…2.5 A) allows for precise matching to the load characteristics, which is particularly important when protecting various types of motors. Phase failure protection further increases the safety of the installation, protecting the motor from damage caused by voltage asymmetry.

Functionality and installation

The MPE25-2.5 starter is characterized by a solid construction for permanent mounting. The connection of the main contacts is made using frame clamps, which facilitates and speeds up installation. The rated short-circuit breaking capacity of 100 kA at 400 V AC ensures effective protection in the event of serious overvoltages. The degree of protection IP20 means that the device is protected against touching with a finger and the ingress of solid objects larger than 12.5 mm – a standard for devices mounted in electrical enclosures.

Additionally, it is worth mentioning the rated power for AC-3 of 0.75 kW at both 230 V and 400 V, which makes it a suitable choice for a wide range of applications in industry and construction. The lack of an integrated auxiliary contact and undervoltage release allows for cost optimization where these functions are not required.
