Working Conditions

- Operating Temperature: Functions effectively between -5°C to +55°C; ensure the environment stays within this range.
- Humidity: Maximum 90% relative humidity during the wettest month, with a minimum temperature of 25°C to avoid condensation.
- Altitude: Suitable for use up to 2000 meters; consult the manufacturer for higher altitudes.
- Pollution Level: Rated for level 3 pollution, common in industrial and commercial settings.
- Magnetic Field: External magnetic field should not exceed five times Earth's natural magnetic field to avoid interference with operation.

Communication Methods

- RS485 Communication: The circuit breaker features an RS485 communication port for connecting to other devices, allowing for integration into larger automation and control systems.
- Ethernet Communication: The breaker can be connected to an Ethernet network via an external communication module, enabling easier data transmission and remote monitoring.
- Mobile Monitoring via App: With built-in wireless communication, the breaker supports remote monitoring through a mobile app, allowing users to track performance and make adjustments from anywhere.
- Cloud Connectivity: Data can be transmitted wirelessly to a cloud platform, where it is stored and accessible for up to 90 days without the need for additional server infrastructure.
