The TY series electric energy metering box is designed for accurate energy metering in three-phase power systems. It converts high voltage signals into low voltage signals via transformers, monitors real-time parameters (current, voltage, power), and provides overload and short circuit protection.
They are suitable for AC 50Hz or 60Hz power supply systems. The rated working voltage ranges up to 220V, 380V, and 690V, with a rated working current range of 10A to 250A.
Common application scenarios include industrial enterprises (factories and production lines), commercial buildings (large facilities), power companies (substations and distribution networks), and public facilities like schools and hospitals.
The "SX" code indicates that the enclosure is an SMC non-metallic metering box, providing excellent durability and insulation properties.
While both use molded case circuit breakers and CDBK-type power supply breakers, the TY-SXS3-1A features one incoming and one outlet switch (250A). The TY-SXS3-2A features a main incoming line (250A) and two separate outlet switches rated at 200A and 125A respectively.
