## Long description

ORNO OR-WE-504 is an electronic single-phase electric energy meter designed to measure active energy consumption in 230 V AC installations. The device operates at a mains frequency of 50 Hz and is specified for a rated current of 5 A. Its compact white enclosure with dimensions 19.5×50×97.2 mm is made for mounting on a standard DIN rail, making it suitable for consumer distribution boards and compact electrical panels where space is limited.
Advantages
The meter provides accurate single-phase energy measurement in a slim DIN-rail housing, enabling space-efficient installation. Electronic measurement increases stability and reduces mechanical wear compared with electro-mechanical alternatives. The standardized 230 V, 50 Hz compatibility ensures straightforward integration into common residential and light commercial installations.
Suitable for
Measuring active energy consumption in residential electrical panels
Monitoring small commercial or office single-phase circuits
Installation in compact DIN-rail consumer units
Applications requiring a low-rated current meter (up to 5 A)
Key specifications
Supply voltage: 230 V AC
Operating frequency: 50 Hz
Rated current: 5 A
Measurement type: single-phase active energy
Mounting: standard DIN-rail
Housing color and material: white enclosure, compact form factor
Dimensions (W×D×H): 19.5×50×97.2 mm
How to use
Mount the meter on a standard DIN rail inside the electrical distribution board. Connect the line and neutral conductors to the designated terminals following local wiring rules and safety regulations. Verify that the supply is 230 V AC at 50 Hz and that the connected load does not exceed the 5 A rated current. After correct wiring and power-up, the device will display cumulative active energy consumption for the monitored circuit.
Usage recommendations
Install and service the meter only with the power switched off and by a qualified electrician. Ensure the meter is placed in a dry, vibration-free environment and protected from direct sunlight and excessive heat. For circuits with higher currents, use an appropriate external current transformer or a meter rated for the required current.
