Electricity meter LE-03d CT-400 - three-phase, LCD display, class 1, measurement input 3x5A [400/5 current transformer] LE03D-CT400

Electricity meter for indirect applications

This three-phase electricity meter LE-03d CT-400 is designed to measure energy consumption in indirect systems. It is a reliable solution for both professional installers and end-users looking for precise energy monitoring. The device works with current transformers with a secondary current of 5A, allowing measurement over a wide range of loads. Using transformers with appropriate parameters ensures an accurate reading of actual energy consumption.

Design and functionality

The LE-03d CT-400 meter uses an electronic circuit to generate pulses proportional to the energy consumed in each phase. Information about energy consumption in individual phases is indicated by the flashing of LEDs (L1, L2, L3), and the sum of pulses from three phases is presented on a clear LCD display. Additionally, the device has an S0+, S0- pulse output, allowing connection of an external device for remote data reading. The meter design allows for sealing of the terminal covers, which protects against manipulation and ensures the integrity of the measurement.

Features and benefits

• Three-phase measurement: ideal for three-phase power systems.
• Indirect system: requires cooperation with current transformers, allowing measurement of large currents while maintaining safety.
• Accuracy class B: ensures precise measurements in accordance with IEC61036 standards.
• LCD display: a clear display makes it easy to read energy consumption.
• S0 pulse output: enables integration with monitoring systems and remote data reading.
• Counter rollback protection: protects against unauthorized interference with readings.
• Width of 7 modules: compact dimensions allow for easy mounting on a 35mm rail in a distribution box.
• Protection class IP20: provides protection against touch and dust.
• National approval: possibility of legalizing the device in accordance with applicable regulations (check current requirements).

The LE-03d CT-400 meter is a solid and precise device that will work in both commercial and domestic applications where accurate measurement of electricity consumption is required. Its design and functionality make it a reliable element of the electrical installation.
