Current transformer DIN 500/5 METSECT5MC050

Current transformer for busbars and cables – reliable measurement in your installation

This current transformer, designed for DIN-rail mounting, is an ideal solution for precise current measurement in electrical installations. Its tropicalized construction ensures excellent performance under harsh environmental conditions. Designed for both professional installers and end users, it provides safe and accurate current measurement in circuits up to 500 A.

Construction and Application

The METSECT5MC050 transformer is a through-type device, meaning the primary conductor carrying current passes through its aperture. This allows for current monitoring without interrupting the circuit. The 41 x 41 mm aperture accommodates various types of cables and busbars, accepting conductors with dimensions of 40.5 x 10.5 mm, 32.5 x 20.5 mm, or 25.5 x 25.5 mm. The transformer is suitable for energy consumption monitoring systems, overload protection, and control and automation circuits.

Key Features and Benefits

• Wide measurement range: Primary current up to 500 A enables use in diverse industrial and commercial installations.
• High accuracy: Class 1 accuracy ensures precise secondary current measurement (5 A), critical for correct operation of monitoring and control systems. Accuracy class 0.5 is achievable with load up to 10 VA, enhancing measurement precision in critical applications.
• Universal mounting: DIN-rail mounting simplifies integration with existing electrical systems. Additionally, the transformer can be mounted on a busbar or mounting plate.
• Robust construction: Tropicalized design guarantees resistance to moisture and corrosion, ensuring long-term, reliable operation even in demanding environmental conditions.
• Safe operation: Lack of touch protection requires caution during installation and operation – the transformer is not intended for direct contact while energized.
• Impulse voltage withstand: Rated impulse voltage withstand of 3 kV provides protection against sudden voltage surges in the electrical network.
• Overload factor FS 5: Allows short-term current overload significantly exceeding the rated value without damaging the device – essential during motor starting or other high-inrush-load applications.

Technical Parameters in Practice

The rated secondary current of 5 A is a standard in many measurement and control systems, facilitating seamless integration with existing devices. The rated apparent power of 12 VA defines the maximum load the secondary winding can handle without loss of measurement accuracy. The 32 mm aperture diameter allows compatibility with conductors of varying thickness. Class B insulation ensures safe operation across a range of temperature conditions.
