Power limiter 100W - 3kW with adjustable time from 0 to 90s type: PMM-02, EXTA EXT10000252

Power limiter – protection of installation and energy consumption control

The PMM-02 power limiter is a reliable device designed to automatically switch off the power in a circuit when the power consumption exceeds the set threshold. This is a key solution to ensure the safety of the electrical installation and avoid overloads, especially when connecting devices with high power demand. The device finds application both in domestic and industrial installations, where precise energy consumption control is essential.

Functionality and flexibility

PMM-02 offers a wide range of power adjustment – from 0.1 kW to 3 kW – allowing it to be adapted to various needs. Adjustment is done smoothly using a potentiometer, ensuring precise settings. In addition, the relay deactivation time after exceeding the power threshold can be adjusted from 10 to 90 seconds, allowing you to adapt the device's reaction to the specifics of the load. A control light indicates exceeding the power threshold, and another light indicates the supply voltage.

Installation and application

The PMM-02 limiter is mounted on a standard TH-35 rail, making it easy to integrate with the existing electrical installation. The compact one-module housing (90 x 17 x 66 mm) allows for efficient use of space in the switchgear cabinet. The device is resistant to short-term exceedances of the set power level, which increases its reliability and durability.

• Overload protection: Prevents damage to the installation caused by excessive current draw.
• Power consumption control: Allows monitoring and limiting electricity consumption.
• Protection against unauthorized power consumption: Effectively protects against illegal use of energy, e.g. in common building areas.
• Flexibility: A wide range of power and deactivation time adjustment allows adaptation to different applications.
• Easy installation: Standard dimensions and installation method facilitate installation.

The device is particularly useful in situations where devices with high power demand occur during start-up (e.g. motors), where a short-term current surge could cause a traditional overcurrent switch to trip. PMM-02 avoids unnecessary power outages while providing effective protection of the installation against overload.
