PowerLogic DIN 250/5 current transformer or busbar trunking system METSECT5MC025

Professional current transformer for demanding applications

The PowerLogic METSECT5MC025 current transformer is a tropicalized solution designed specifically for busbars and cables in industrial applications. The device provides precise current measurement of 250A with a secondary output of 5A, making it ideal for monitoring loads in electrical switchboards.

Construction, electrical parameters, and measurement accuracy

The current transformer features a measurement opening of 41×41mm and a through diameter of 32mm, allowing for the installation of various types of conductors and busbars. The compact design (70×95×65mm) enables installation in limited switchboard spaces.

Electrical parameters include a rated secondary apparent power of 5VA with an overcurrent factor of FS5, ensuring safe operation even during transient current surges. The device maintains a rated insulation voltage Ui=3kV and an impulse withstand voltage Uimp=3kV, guaranteeing operational safety.

The transformer offers two accuracy classes tailored to different applications:

• Class 0.5 at a maximum power of 3VA - for precise energy monitoring
• Class 1 at a maximum power of 5VA - standard operational measurements

This division allows for the optimization of installation costs while maintaining the required measurement accuracy for a specific application.

The product meets the requirements of international standards:

• VDE0414 - German standard for measuring transformers
• IEC61869-2 - international standard specifying technical requirements

The device holds CE (Europe) and EAC (Eurasian Customs Union) certifications, confirming compliance with European electrical safety standards.

Compatibility and mounting options

The transformer is compatible with three standard busbar configurations:

• 40,5×10,5mm - for larger busbars
• 32,5×20,5mm - universal solution for medium installations
• 25,5×25,5mm - compact applications

Mounting is possible on a DIN rail, mounting plate, or directly onto the busbar using clips or insulated screws. The secondary connection is made via robust screw terminals, ensuring reliable electrical contact.

Operating conditions and environmental resistance

The device maintains full functionality across a wide temperature range from -25°C to +60°C at a relative humidity of 0-95%. Tropicalization guarantees resistance to corrosion and material degradation in harsh environmental conditions.

The IP20 protection rating protects against contact with live parts while simultaneously allowing free ventilation. The transformer withstands a short-circuit thermal current Ith=15kA and dynamic surges up to 2.5Ith, ensuring safety even during short circuits.
