Wholesale China Suppliers Factory TY-SXD1-FSH1 Waterproof Box for IP44 Protection Against Moisture and Dust Manufacturers, Factories
Product Description
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°. Deploy in a cool and dry environment, avoiding continuous direct sunlight. Site selection principle: no mechanical vibration/strong impact source, no chemical corrosion risk area.
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.
Standardized Installation Process
Box Opening
Remove the central fixing screw at the bottom and open the box according to the standard process.
Basic Fixation
Locate the wall drilling point according to the preset hole position, lock the base after implanting the expansion tube, and proceed with the final assembly of the upper cover.

Frequently Asked Questions
What are the electrical ratings supported by TY series meter boxes?
TY series meter boxes are suitable for power supply systems with rated current ranging from 10A to 250A, operating voltage from 220V to 690V, and dual frequency compatibility of AC 50Hz or 60Hz.
What are the environmental requirements for normal operation?
The operating environment temperature must be between -25℃ and +50℃ (with 24-hour average ≤+35℃). Relative humidity should not exceed 80% at 40℃ under clean air conditions, with higher humidity permitted at lower temperatures.
What is the required vertical installation tolerance?
The enclosure requires vertical mounting, with the inclination angle strictly maintained within ≤5° in a vibration-free, non-corrosive, and dry setting away from direct sunlight.
Which chemicals should the enclosure be protected against?
Avoid exposure to strong alkalis, oxidizing acids, amines, ketones, chlorinated hydrocarbons, and aromatic solvents to preserve material integrity.
What are the short-circuit capacity and ingress protection levels?
The main busbar system provides a short-time withstand current of ≥30kA, and the unit features an IP44 protection level against dust ingress and liquid splashes.
How is the meter box securely mounted to the wall?
Remove the bottom central fixing screw to open the cabinet, mark and drill according to preset holes, insert expansion tubes, fasten the base securely, and reassemble the upper cover.
