Key Features- Trip time display: A large digital display shows the RCD's tripping time.
- Operating voltage: 230V \(\pm \) 10%, 50/60Hz. A related model, the TES-1900B, is designed for 110V.
- Wiring status check: Three LEDs provide a visual indication of the correct wiring status.Phase angle selection: Includes a 0° and 180° phase angle switch for comprehensive testing and consistent readings.
- Trip current settings: Tests for rated tripping currents of 10, 20, 30, 100, 300, and 500mA.
- Trip current factors: The test current can be set to x1/2, x1, and x5.
- Overheating protection: An automatic lockout feature prevents testing if the test resistor overheats.
- Safety features: A microprocessor-controlled system provides high accuracy and reliability, and the device indicates reversed phase and neutral wiring.
- Durability: The casing is made from resilient plastic to withstand daily use.
