How to Use
- Preparation: Ensure the main power supply is fully de-energized before attempting installation.
- Mounting: Secure the circuit breaker onto the mounting plate or DIN rail within your distribution panel using the appropriate hardware.
- Wiring: Connect the line and load cables to the terminals. Use a calibrated torque wrench to ensure all connections meet the manufacturer’s specified tightness to prevent overheating.
- Configuration: If the model includes an adjustable trip unit, set the thermal and magnetic parameters according to your system's load requirements.
- Testing: Utilize the "Push-to-Trip" button located on the front face of the unit to manually verify the mechanical tripping mechanism before commissioning.
Care & Safety
- Professional Installation: This equipment must be installed, adjusted, and maintained only by qualified electrical personnel.
- Environment: Store and operate in a dry, dust-free environment. Avoid exposure to corrosive gases or excessive moisture which can degrade internal components.
- Maintenance: Periodically inspect terminal connections for signs of heat discoloration or loosening.
- Safety Warning: Never attempt to disassemble the molded casing or modify the internal trip units, as this can lead to catastrophic failure or electrical fire.
