Energy consumption meter 3-phase LE-03d CT400 F&F
Product description
Three-phase. For semi-direct measurement. 400 A current.
LE-03 CT400 are static (electronic) calibrated electricity consumption meters serving as sub-meters for measuring three-phase AC electricity in a semi-direct system.
The meters are designed to work with current transformers with a secondary current of 5 A. The maximum measured current of the system is determined by the value of the primary current of the applied current transformer. When using transformers with dedicated parameters, the meters show the actual value of the electricity consumed by the system.
Operation
A special electronic circuit under the influence of the flowing current and applied voltage in each phase generates pulses in an amount proportional to the consumed electricity in that phase. Energy consumption in a phase is indicated by flashing of the corresponding LED (L1, L2, L3). The sum of the pulses from the three phases signaled by the blinking of the LED (300 imp/kWh) is converted into energy consumed in the entire three-phase system and its value is indicated by the segmented LCD display.
Note:
The meter has a pulse output SO+ - SO-. This allows you to connect another pulse reading device (SO) generated by the meter. It is not required to connect an additional device for proper operation of the meter.
The meter has the ability to seal the covers of the input and output terminals to prevent making a bypass of the meter.
