Electricity meter LE-03d CT-200 - three-phase, LCD display, class 1, measuring input 3x5A [current transformer 200/5] LE03D-CT200

Three-phase energy meters – precise measurement and reliability

The LE-03d CT-200 electricity meter is an advanced device designed to measure electricity consumption in three-phase installations. It uses an indirect measurement method, which means it works with current transformers, providing flexibility and the ability to adapt to different current ranges. It is a solid solution for both professional installers and end-users who need accurate energy consumption monitoring.

Construction and operating principle

The LE-03d CT-200 is an electronic meter that converts signals from current transformers into pulses proportional to the energy consumed. These pulses are then summed and displayed on a clear LCD display. This allows for precise reading of active power consumption in each phase and total energy consumption. The meter's anti-tamper feature ensures data integrity and protects against manipulation.

Application and benefits

The LE-03d CT-200 meter finds application in a wide range of facilities, such as:

• Residential and commercial buildings
• Industrial plants
• Small and medium-sized enterprises
• Sub-metering installations – ideal for monitoring energy consumption by individual receivers or building segments.

Why choose LE-03d CT-200?

• Measurement accuracy: Accuracy class B guarantees reliable measurement results, in accordance with IEC61036 standard.
• Flexibility: Cooperation with current transformers with a secondary current of 5A allows you to adapt the meter to different primary current ranges, which is especially important in installations with variable loads. The maximum measured current of the system depends on the primary current value of the transformer used.
• S0 impulse output: Enables integration with building automation systems (BMS) or other devices for remote data reading and energy consumption analysis. The impulse output generates 300 impulses per kWh, which facilitates integration with various systems.
• Clear LCD display: Provides easy reading of information about energy consumption in each phase and total power consumption.
• Compact dimensions: Width of 7 modules (122 mm) makes it easy to mount in standard electrical panels on a 35 mm rail.
• Safety: Protection class IP20 provides protection against accidental contact and interference caused by small solid particles.
• Compliance with standards: Meets national approvals and IEC61036 and IEC62052-11/IEC62053-21 standards, confirming its quality and safety of use.

Additionally, the meter has a lock on the input and output terminals, which prevents unauthorized access and manipulation. The indication of current consumption by LEDs in each phase facilitates visual control of the installation's operation.
