China Suppliers Factory TY-SXD1-FSH1 Waterproof Box for IP44 Meter Protection Against Moisture and Dust
Product use scope and conditions of use
The TY series of electric energy meter boxes integrate single-phase and three-phase types, and are suitable for power supply systems with rated current of 10A-250A, AC 50Hz or 60Hz, and voltage of 220V to 690V, and perform single-phase and power electric energy metering and control tasks; its operating environment requires a temperature range of -25℃～+50℃ (average temperature ≤+35℃ within 24 hours), and the relative humidity does not exceed 80% at 40℃ under clean air conditions, and higher humidity levels are allowed under low temperature conditions.
Installation Specifications
◆ Pre-installation checks
Thoroughly check the structural integrity and component completeness of the cabinet before installation.
◆ Targeting criteria
- Use vertical installation, and the inclination angle is strictly controlled within the range of ≤5°
- Site selection principle: no mechanical vibration/strong impact source, no chemical corrosion risk area
- Deploy in a cool and dry environment, avoiding continuous direct sunlight
◆ Chemical protection requirements
Do not contact with strong alkalis, oxidizing acids, amines, ketones, chlorinated hydrocarbons and aromatic solvents.
◆ Physical protection measures
During use, be careful to prevent collisions and scratches with sharp objects to keep the surface protective layer intact.
