Motor starter MPE25-40 004648015

Motor starter – reliable protection for your devices

This three-pole MPE25-40 motor starter is a solid solution for protecting electric motors in installations with a voltage of 400-690V. It provides effective protection against overload and short circuit, and also has a built-in phase failure sensitivity function, which minimizes the risk of motor damage in the event of voltage asymmetry. The device's design, intended for permanent mounting, guarantees stability and long-term operation.

Functionality and application

The MPE25-40 starter is ideal for use in industry, construction and workshops. Thanks to the overload release setting range of 32-40A, it can be adapted to various motor loads. The rated operating power for AC-3 is 11 kW at 230V and as much as 18.5 kW at 400V, making it a suitable choice for a wide range of applications. Frame terminals facilitate cable connection, and the knob allows for convenient device control.

Key features:

• Overload and short circuit protection: Ensures the safety of the installation and protects motors from damage.
• Phase failure sensitivity: Detects the absence of one phase and disconnects the circuit, preventing overheating and damage to the motor.
• Wide current setting range: Allows precise adjustment to the specific load (32-40A).
• High breaking capacity: Rated breaking capacity Icu at 400V is 30kA, which guarantees effective disconnection in the event of a short circuit.
• Durable construction: The permanently mounted device ensures stability and reliable operation for a long time.
• Thermal-magnetic release method: Combining thermal and magnetic protection provides comprehensive protection.

Technical specifications

The MPE25-40 is characterized by compact dimensions (98 mm depth x 45 mm width x 97 mm height) and a degree of protection of IP20, which provides basic protection against touch and ingress of solid objects. The rated continuous current (Iu) is 40A, and the short-circuit release setting range is 520A. The device does not have an integrated auxiliary contact or undervoltage release. It is made of high-quality materials ensuring long-term use.
