B23 212-100 — ABB B23 Three-Phase Energy Meter
The ABB B23 is a Class 1 three-phase four-wire electronic energy meter for commercial and industrial sub-metering, measuring active energy (kWh), reactive energy (kVARh), and apparent energy (kVAh) in both import and export directions with a 7-module DIN rail mounting format and RS-485 Modbus RTU communication as standard. Available in direct-connected versions up to 65 A and CT-connected versions via 5 A or 1 A secondary current transformers, the B23 covers three-phase metering requirements from small commercial tenancies at 30–40 A through to large industrial premises with 2000 A+ supply circuits measured through 2000/5 A CTs. The simultaneous measurement of active and reactive energy makes the B23 the single instrument needed for comprehensive tenant energy billing, power factor assessment, and reactive energy monitoring without additional instruments.
The B23's Modbus RTU communication port provides real-time access to a comprehensive set of energy and power quality parameters — per-phase voltage, per-phase current, power factor, frequency, total harmonic distortion (THD-V, THD-I), maximum demand, and time-of-use energy registers — enabling building energy management systems to monitor tenant consumption, identify power quality issues, and generate energy reports without additional metering or logging hardware. A programmable pulse output (S0) provides energy pulse output for legacy BMS wiring and BACS (Building Automation and Control Systems) integrations where Modbus RS-485 is not available, ensuring backward compatibility with older building management infrastructure across Saudi Arabia's large installed base of commercial buildings.
In Saudi Arabia's commercial real estate market, the B23 is the standard three-phase energy meter for Class A and B office towers, retail centres, and mixed-use developments across Riyadh's Northern Ring Road, Jeddah's Al Hamra and Tahlia corridors, and the commercial zone of Al Khobar. REIT (Real Estate Investment Trust) property management companies, which are growing rapidly under the Vision 2030 capital market development program, specify B23 meters for tenant energy monitoring as a prerequisite for LEED and MODON Green certification. Healthcare facilities, hotels, and universities use B23 meters for department-level energy metering aligned with ISO 50001 energy management system requirements increasingly adopted by large Saudi organisations. ARAMCO residential compounds and industrial client facilities use B23 meters for cost allocation across production units and support buildings.
Razz Middle East stocks B23 meters in all standard configurations and supplies to panel builders, M&E contractors, BEMS integrators, and facilities management companies across Saudi Arabia. We provide Modbus configuration services, CT ratio programming, integration support for Johnson Controls Metasys, Honeywell EBI, Siemens Desigo, and Schneider EcoStruxure BEMS platforms, and full metering system commissioning.

Key Features & Benefits
- Simultaneous measurement of active (kWh), reactive (kVARh), and apparent (kVAh) energy in import and export directions provides comprehensive tenant energy billing data and reactive power monitoring for SEC tariff management in a single instrument.
- RS-485 Modbus RTU communication as standard (not optional) exposes real-time per-phase voltage, current, power factor, frequency, THD, and maximum demand registers for direct integration into any BEMS or AMR platform without additional gateways.
- Programmable CT ratio entry allows the same B23 to serve direct-connected 65 A circuits and large industrial circuits measured through 2000/5 A current transformers, covering the full range of three-phase commercial and industrial sub-metering applications.
- Time-of-use (TOU) energy registers record separate kWh totals for up to 4 tariff periods, enabling tenant billing aligned with SEC's time-of-use tariff structure for commercial and industrial customers above certain annual consumption thresholds.
- Class 1 accuracy per IEC 62053-21 across the full current range from 2% to 200% of rated current satisfies SEC sub-metering accuracy requirements for commercial tenant billing and meets LEED measurement and verification protocols.
- S0 pulse output provides kWh pulse counting for legacy BAS/BACS systems and data loggers that do not support Modbus RS-485, ensuring backward compatibility with older building management infrastructure in Saudi Arabia.
- Maximum demand register records peak kVA demand with configurable averaging interval (15 or 30 minutes), enabling building operators to identify demand peaks for maximum demand tariff optimisation and peak demand management strategies.
Industrial Applications in Saudi Arabia
- Commercial office tower tenant energy metering across Riyadh's KAFD, Olaya, and North Ring Road business districts, where B23 Modbus meters connected to the building's Modbus TCP gateway enable automated monthly tenant energy billing.
- Shopping mall retail unit energy metering in Riyadh Park, Mall of Arabia, and Jeddah's Red Sea Mall, where per-unit measurement enables fair energy cost recovery from tenants based on actual consumption with time-of-use register capability.
- Industrial unit energy metering at MODON industrial estates and SAGIA economic zones, where individual workshop meters enable the estate operator to bill occupiers for actual electricity consumed rather than estimated or pro-rata allocation.
- Hotel department and venue energy metering at Makkah and Madinah hotels, Five-star Riyadh properties, and Red Sea Project resorts, where B23 meters by floor, HVAC zone, and F&B outlet support ISO 50001 energy management program data collection.
- Healthcare facility department metering at MOH hospitals and Vision 2030 healthcare infrastructure, where B23 kVAh measurements track reactive consumption by major loads as part of ISO 50001 energy management and SEC reactive tariff management.
- University campus building and department metering for KAU, KFUPM, and KAUST energy management programs, where Modbus connectivity enables centralised energy reporting across hundreds of metering points on the campus BEMS.
- ARAMCO residential compound and industrial facility energy metering for internal cost allocation, where B23 meters replace manual estimation with measured data aligned with ARAMCO's facility energy management and reporting requirements.
