Datasheet Summary with AI

1. General Product Information (MEWT ES-1921)

️· Model: MEWT ES-1921
️· Manufacturer: M-System (refer to URLs)
️· Type: Seems to be a current transformer (CT) or related metering/monitoring device. It's used to measure electrical current.
️· Website: [http://www.m-system.co.jp/](http://www.m-system.co.jp/) (for more details)

2. Electrical Specifications

️· Input Voltage Range: Not explicitly stated, but it’s intended for use with mains voltage (likely 100-240V AC).
️· Isolation Voltage: Information about isolation voltage isn't provided.
️· Operating Temperature: Not specified in these images.
️· Consumption/Load: Not specified.

3. Mechanical Specifications & Dimensions

️· Mounting: DIN Rail mounting (35mm wide)
️· Mounting Hole Size: 2–4.5 mm diameter
️· Mounting Hole Depth: 25 mm
️· Screw Size: 11–M3.5
️· Overall Dimensions (approximate, from drawings - units are in mm, with conversions to inches in parentheses):
- Height: 107 (4.21) and 136 (5.35) - likely referring to different configurations or mounting options.
- Width: Variable (based on specific configuration)
- Depth: 80 (3.15) and 40 (1.57) with more components at 50(1.97).
️· CT Protector (CTM) Placement: Important for wiring.
- Single-Phase / 2-Wire: CT Protectors on terminals 2 and 1.
- Three-Phase / 3-Wire: CT Protectors on terminals 1 and 2.

4. Wiring & Terminal Information

️· CT Protector (CTM) Placement: Important for wiring.
- Single-Phase / 2-Wire: CT Protectors on terminals 2 and 1.
- Three-Phase / 3-Wire: CT Protectors on terminals 1 and 2.

5. Key Considerations & Notes

️· DIN Rail Mounting: Easy mounting to standard 35mm DIN rails.
️· CT Protector (CTM) Placement: Crucial for proper operation. This device is often used in conjunction with a CT Protector for current measurement. The placement depends on the connection type (single-phase 2-wire vs. three-phase 3-wire).
️· Close Mounting: "When mounting, no extra space is needed between units" - suggesting this is designed for multi-unit installations.
️· CT Protector (CTM) Placement: important for wiring.
- Single-Phase / 2-Wire: CT Protectors on terminals 2 and 1.
- Three-Phase / 3-Wire: CT Protectors on terminals 1 and 2.
