5. Návod k obsluze
The XT2 N 160 circuit breaker features a simple ON/OFF mechanism and an Ekip trip unit for protection settings.
- Zapínání: To energize the circuit, push the main toggle handle to the 'ON' position.
- Vypínání: To de-energize the circuit, push the main toggle handle to the 'OFF' position.
- Zablokovaný stav: If an overload or short circuit occurs, the breaker will automatically trip, moving the handle to an intermediate position. To reset, first move the handle fully to the 'OFF' position, then to 'ON'. Investigate the cause of the trip before resetting.
- Ekip Trip Unit Settings: The Ekip trip unit allows for precise adjustment of protection parameters such as long-time (Ir), short-time (Isd), instantaneous (Ii), and ground fault (Ig) protection. Refer to the detailed Ekip manual for specific programming instructions. The image shows dials for adjusting these settings.
- Testovací tlačítko: A 'Test' button is typically present on the trip unit to verify the mechanical and electrical operation of the breaker. Pressing this button should cause the breaker to trip.
