Finder 7M.24.8.230.0310 – 7M Series Energy meters

Why Choose the Finder 7M.24.8.230.0310 Single-Phase Energy Meter?

The Finder 7M.24.8.230.0310 is a compact, multifunction single-phase bidirectional energy meter designed for accurate electricity consumption monitoring, energy management and remote metering applications. Part of the Finder 7M Series, this smart electricity meter combines MID certification, integrated M-Bus communication, NFC technology and a backlit LCD display in a space-saving DIN rail-mounted housing.

Designed for 230 V AC single-phase electrical systems, the Finder 7M.24.8.230.0310 provides direct-connected energy measurement with a 5 A reference current and 40 A maximum current. Its bidirectional measurement capability enables monitoring of imported and exported active energy, making it suitable for electrical distribution systems, photovoltaic installations, building energy monitoring and industrial sub-metering applications.

The integrated M-Bus communication interface enables connection to compatible metering networks and building management systems. Additional infrared communication and NFC technology support convenient meter interaction and configuration through the Finder Toolbox App. With a housing width of just 17.5 mm, the meter occupies only one DIN rail module, making it particularly suitable for installations where panel space is limited.

Intelligent Energy Monitoring with M-Bus and NFC Technology

The Finder 7M.24.8.230.0310 provides comprehensive electrical energy monitoring for single-phase installations. In addition to recording imported and exported active energy, the meter can display reactive energy and instantaneous electrical parameters including voltage, current, power factor, active power, apparent power, reactive power, frequency and total harmonic distortion. These measurements help electrical engineers and energy managers understand consumption patterns, identify abnormal operating conditions and evaluate electrical system performance.

The integrated M-Bus interface enables energy measurement data to be collected through compatible wired metering networks. This makes the meter particularly useful for building management systems, centralised energy monitoring, commercial sub-metering and installations with multiple electricity meters. Its NFC functionality allows compatible smartphones running the Finder Toolbox App to configure the meter and access stored energy readings, including when mains voltage is unavailable.

The combination of MID-certified measurement, bidirectional monitoring, a backlit LCD display and compact DIN rail construction makes the Finder 7M.24.8.230.0310 a versatile solution for modern electrical installations. Its direct-connected 40 A measurement capability simplifies installation, while the sealable terminal cover helps maintain the integrity of the metering arrangement.
