Product Overview
Our 60A single-phase anti-interference meter connector is a specialized component designed for residential single-phase metering systems, providing a secure, interference-free connection between single-phase meters and the power supply. This connector is engineered to prevent unauthorized access, tampering, and electromagnetic interference, ensuring accurate meter readings and compliance with utility regulations.
Key Differences from Three-Phase Connectors
| Feature | Single-Phase Anti-Interference Connector | Three-Phase Anti-Interference Connector |
| Application | Residential single-phase metering | Commercial/industrial three-phase metering |
| Rated Current | 60A, suitable for most residential loads | 60A/80A/100A, suitable for higher commercial/industrial loads |
| Number of Poles | 2 poles (phase + neutral) | 4 poles (3 phases + neutral) |
| Size | Compact, designed for residential meter boxes | Larger, designed for commercial meter boxes |
| Key Function | Prevents tampering and interference in residential systems | Prevents tampering and interference in three-phase systems |
Anti-Interference & Anti-Tampering Principle
The "Anti-Interference" feature of this connector refers to its specialized design that suppresses electromagnetic interference (EMI) and radio frequency interference (RFI) that can disrupt the accuracy of single-phase smart meters. Additionally, it incorporates a physical anti-tamper design that prevents unauthorized disconnection or modification of the meter wiring, with built-in security features that alert utility companies to any attempt to bypass or tamper with the meter connection.
The connector's keyed design ensures that it can only be connected in the correct orientation, preventing reverse polarity connections and miswiring. The sealed housing also prevents access to the live terminals, eliminating the risk of unauthorized wiring and electricity theft.

Installation Guidelines
Ensure the residential meter box is de-energized and all power is disconnected before installation.
Align the connector with the single-phase meter's terminals, ensuring the keyed design is correctly oriented, and push firmly to create a secure plug-in connection.
Secure the connector to the meter box using the provided mounting screws.
Connect the main power cables to the connector's input terminals, following the phase and neutral labeling.
Tighten all screws to the recommended torque, and apply security seals to the anti-tamper holes if required.
Verify all connections are secure and the meter is reading correctly before restoring power.
