State Grid SMC Series Single-Phase 10-Position Metering Box
The SMC single-phase 10-position metering box is a box-type assembly for low-voltage energy metering at 380/220 V and below. It is primarily used to install core metering components such as electricity meters, meeting the functional requirements of energy metering, anti-tampering, and remote meter reading.
Product Description
Non-Metallic Meter Box (SMC Material)
Wall-mounted or floor-standing installation, secured with built-in expansion bolts.
For outdoor installation, IP34D protection rating is required; for indoor installation, IP20 minimum.

Product Advantages
Energy Metering
Integrates electricity meters, voltage transformers, current transformers, and other devices to achieve accurate measurement of active and reactive energy.
Anti-Tampering Design
Some models (e.g., prepayment metering boxes) eliminate external tampering risks through technologies such as smart circuit breakers and electronic locks.
Remote Management
Supports remote prepayment, load monitoring, and disconnection upon arrears, facilitating utility management.
Direct-Connected
Suitable for single-phase or three-phase energy meters without the need for instrument transformers.
