Description
Analog Panel Ammeter (Pointer Type) E378 (0–200 A / 50 Hz / 160×160 mm)
The E378 series industrial electromagnetic ammeter is designed for accurate and continuous measurement of the RMS value of AC current at a frequency of 50 Hz in the range from 0 to 200 Amperes. The device is housed in a reliable, impact-resistant carbolite square-format casing (160×160 mm) and is intended for flush panel mounting on distribution boards, control panels, and automation cabinets of industrial equipment.
Key Advantages and Features:
- High Reliability and Vibration Resistance: A durable housing with dust- and moisture-proof design (protection degree IP50/IP54) and a vibration-resistant measuring mechanism ensure stable operation in harsh industrial environments.
- Clear Large-Format Scale: The large dial with a 160×160 mm front panel size and high-contrast markings allows the operator to comfortably read current values from a long distance.
- Accuracy Class 1.5: Guarantees minimum measurement error (no more than ±1.5% of the upper limit of the scale).
- Mechanical Zero Adjuster: A slotted adjustment screw is located on the front panel for precise setting of the pointer to the zero position before operation [cite: 19].
- Wide Temperature Range: Operates reliably at ambient temperatures from -40 °C to +50 °C and relative humidity up to 95%.
Compatibility and Applications:
- Industrial distribution boards, input-distribution devices (ASU, MSB, ShO-70).
- Power control cabinets for asynchronous electric motors, pumping stations, and compressors.
- Transformer substations (KTP), laboratory test benches, and generator sets. ...
- E378 Panel Ammeter (0–200 A) — 1 pc.

Pro Tip: The device is designed for vertical installation on a panel. Before applying a load, adjust the pointer exactly to the zero mark of the scale using the zero adjuster. 200 A ammeters are connected to the power circuit via a current transformer (e.g., 200/5 A) or directly (depending on the internal design of the device). When mounting terminals on the rear panel, tighten the nuts carefully to avoid overheating the contacts.
