Three-Phase + Neutral Main Switch: Provides main circuit protection and full isolation (including neutral) for distribution boards.
Industrial Machinery: Protecting 3-phase equipment requiring simultaneous neutral disconnection for safety or control reasons.
Commercial Distribution Panels: Branch circuit protection for 3-phase loads where 4-pole breaking is specified, especially in compact panels.
Data Centers / UPS Systems: Protecting input or output circuits where neutral integrity and full isolation during faults or maintenance are critical.
Applications requiring Curve 2: Suitable for general three-phase loads like resistive heating, lighting, or motors with moderate starting currents.
Confirm Configuration: Ensure the 3P+N (3 protected poles, 1 switched neutral) configuration is correct for the application.
Voltage Rating: Verified for 415 Vac Line-to-Line systems.
Interrupting Capacity: Check that the 6kA rating is sufficient for the installation's fault level.
Curve Choice: Curve 2 is general purpose; consider if Curve 1 is needed for higher inrush loads.
Mounting System: Compatible with both standard DIN rail and Mini Rail systems.
Wiring: Connect L1, L2, L3 to the protected poles and Neutral to the switched (unprotected) pole. Use appropriate wire sizes (0.75-25mm² IEC) and torque terminals to 2.5 Nm (IEC).
Temperature Independence: Ideal for panels with heat sources or fluctuating ambient conditions.
Full Isolation: Leverages the 4-pole simultaneous switching for enhanced maintenance safety.
