State Grid SMC Series Single-Phase 2-Position Meter Box
The SMC single-phase 2-position meter box is a complete box-type assembly for low-voltage energy metering at 380 V, 220 V and below. It is primarily used to house 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.
Outdoor installation must meet IP34D protection rating; indoor installation must be at least IP20.

Product Advantages
Energy Metering
Integrates energy meters, voltage transformers, current transformers, and other devices to achieve accurate measurement of active and reactive energy.
Anti-Tampering Design
Certain models (e.g., prepayment meter boxes) utilize smart circuit breakers, electronic locks, and other technologies to eliminate external tampering risks.
Remote Management
Supports remote prepayment, load monitoring, and automatic disconnection upon arrears, facilitating utility management.
Direct Connection
Suitable for single-phase or three-phase energy meters without requiring current transformers.
