3-phase Energy Meter Energy Meter VM-3P75CT REL200300100, 75 A, CT input, OEM

Three-phase energy meter VM-3P75CT REL200300100 is an OEM device intended for measurement and monitoring of electrical energy in three-phase systems. The meter supports current transformer (CT) input and is rated for up to 75 A per phase, enabling accurate active energy measurement in installations where CT coupling is required. The compact form factor and standard DIN-compatible mounting make it suitable for integration into panels, control cabinets and billing or monitoring systems.

Advantages

This energy meter provides CT input compatibility for safe measurement of higher currents while keeping the meter isolated from the measured conductors. It supports three-phase measurement for balanced and unbalanced loads and delivers stable active energy readings within the specified current range. The device’s OEM design allows straightforward integration into existing electrical metering and control setups, with proven reliability for continuous operation.

Suitable for

• Industrial and commercial three-phase installations requiring centralized energy measurement
• Metering applications where current transformers are used for safety or scaling
• Panel-mounted monitoring and integration into building management or billing systems
• Retrofit projects where DIN-panel space and CT inputs are necessary

Key specifications

• Measurement type: three-phase active energy metering
• Rated current via CT input: up to 75 A per phase
• Input: current transformer (CT) interface for each phase
• Mounting: panel / DIN-compatible mounting form factor
• Output/integration: OEM configuration suitable for connection to external monitoring or billing systems (interface type depends on model variant)
• Operating environment: designed for continuous electrical metering in industrial, commercial and residential electrical panels

How to use

Install the meter on a DIN rail or panel cutout according to the panel layout and the manufacturer’s mechanical instructions. Connect CT secondary windings to the meter’s CT input terminals, ensuring correct phase identification and CT polarity. Supply the meter with the required auxiliary voltage as specified by the manufacturer and verify that voltage connections correspond to the three phases. After wiring, perform an initial verification by comparing meter readings with reference measurements or with the CT secondary nominal values to confirm correct scaling and phase sequence. Follow local electrical regulations and ensure all work is carried out by qualified personnel.

Usage recommendations

Use appropriately rated current transformers for the anticipated primary current and ensure CT secondary circuits remain shorted or connected to the meter when energized. Regularly verify calibration and check wiring integrity during scheduled maintenance to ensure accurate energy accounting and safe operation.
