Usage Environment
The TY series of electric meter boxes of Teyi Electric Co., Ltd. integrates two categories: single-phase and three-phase. They are designed for power supply systems with AC 50Hz or 60Hz, rated working voltage 220V to 690V, and current 10A-250A, realizing efficient integration of single-phase electric energy metering and power electric energy control management. This series of products has excellent environmental adaptability, with an applicable temperature range of -25℃～+50℃ (average temperature within 24 hours ≤+35℃); humidity requires clean air, and the upper limit of relative humidity is 80% at 40℃, and it is compatible with higher humidity levels under low temperature conditions.
Installation and Usage Specifications
Pre-installation checks
Before installation, the integrity of each component of the meter box must be fully checked to ensure that there are no defects or abnormalities.
Installation positioning requirements
- Vertical installation: The tilt angle should be ≤5° (revised according to industry standards) to avoid vibration, impact and corrosive environment.
- Environmental selection: Prefer a cool and dry place, away from direct sunlight and chemical contact areas.
Chemical Protection Warnings
It is strictly forbidden to contact with strong alkali, oxidizing acid, amine, ketone, chlorinated hydrocarbon and aromatic solvent to prevent the material from dissolving or corroding.
Physical protection measures
- Avoid sharp objects from colliding with or scratching the surface of the cabinet.
- The wiring area needs to be kept clean and dust must be removed regularly to ensure heat dissipation.
Cabinet installation process
- 1Remove the two screws fixing the upper cover at the bottom of the box;
- 2Open the box according to the instructions;
- 3Drill holes according to the positioning holes and install the expansion tube;
- 4After fixing the base, assemble the upper cover.
Core Electrical Parameters
◆ Main busbar carrying capacity
- Rated operating current range: 10A~250A
- Rated short-time withstand current: 30kA/1 second (corresponding to peak withstand current 75kA/0.1 second, coefficient 2.5)
◆ Insulation performance
- Rated insulation voltage: 800V
- Normal insulation resistance: ≥20MΩ (standard test conditions)
◆ System adaptability
- Compatible frequency: 50Hz or 60Hz AC system
- Protection level: IP44 (protected against solid foreign objects with a diameter of ≥1mm and splashing water from all directions)
Key Technical Description
- Short-time withstand capability: The 30kA/1 second indicator meets the needs of most power distribution scenarios, and its peak withstand current is designed to be 2.5 times the international standard.
- Insulation matching: 800V insulation voltage covers power supply systems of 690V and below, leaving sufficient safety margin.
- Protection features: IP44 level is suitable for non-extreme pollution environments, and takes into account the balance between heat dissipation and protection.

|---|---|---|---|
| Company Code | SMC non-metallic metering box | Single item single meter box | Junction Box |
The TY series distribution boxes are manufactured using internationally leading SMC (Sheet Molding Compound) glass fiber reinforced composite materials, processed through precision molding technology.
Due to their outstanding corrosion and aging resistance, they offer an indoor service life of up to 40 years and an outdoor service life exceeding 30 years, which is significantly longer than traditional metal or plastic boxes.
They support AC 50Hz or 60Hz systems with rated voltages from 220V to 690V and currents ranging from 10A to 250A. They also feature an insulation voltage of 800V and an IP44 protection rating.
They should be installed vertically (tilt angle ≤5°) in cool, dry areas away from direct sunlight. The operating temperature range is -25℃ to +50℃, with a relative humidity limit of 80% at 40℃.
Yes, to prevent material dissolution or corrosion, you must avoid contact with strong alkalis, oxidizing acids, amines, ketones, chlorinated hydrocarbons, and aromatic solvents.
The installation involves removing the two bottom screws, opening the cover, drilling holes based on the positioning markings, installing the expansion tubes, securing the base, and reassembling the cover.
