Loop impedance meter MZC-20E with Calibration Certificate WMPLMZC20E

Loop impedance meter – precision and safety in one device

The MZC-20E loop impedance meter is an indispensable tool for installers, measurement technicians and maintenance services. The device is designed for precise measurements in low-voltage electrical installations, used in residential buildings, office buildings, industrial plants and other facilities. Compact dimensions and a durable housing make the meter perfect for various working conditions.

Versatile application and key features

MZC-20E enables accurate measurement of loop impedance in networks with a rated voltage of up to 440V. Measurement results are crucial for assessing the safety of the installation and proper selection of protection devices. The device allows for quick and effective diagnostics, minimizing the risk of failure and ensuring compliance with applicable standards. Calculation of prospective short-circuit current I_k further facilitates the assessment of potential hazards. Automatic distinction between phase-to-neutral or phase-to-phase voltage increases work comfort and minimizes the risk of measurement errors.

Practical benefits for the installer and user

• Fast diagnostics: Allows for quick location of potential problems in the electrical installation.
• Precise results: Provides accurate measurements of loop impedance, which translates into safety of use.
• Versatility: Suitable for working in various types of low-voltage electrical installations.
• Compact size: Facilitates transport and work in tight spaces.
• Durable construction: Guarantees reliability and long-term use even in difficult conditions.
• Support for compliance with standards: Helps to meet the requirements regarding electrical safety in accordance with applicable regulations (e.g. PN-HD 60364).
• Prospective short-circuit current calculation: Enables assessment of the potential hazard associated with installation overload.

The MZC-20E meter is particularly useful for testing installations protected by circuit breakers up to 63A, where short-circuit currents can reach 1 kA – typical for residential construction and small industrial facilities. Thanks to this, it allows for effective protection against the effects of short circuits and overloads, ensuring the safety of people and property. Let's remember that proper selection of protection devices is based on knowledge of the loop impedance – and this meter makes it possible!
