Industrial Machinery: Protection for two phases of control circuits or equipment feeds rated up to 415V where 6kA breaking capacity is needed.
Commercial Panels: Branch circuit protection for two-phase loads in installations with high prospective fault currents.
Control Systems: Compact protection for 415V rated control circuits with moderate inrush currents.
HVAC Equipment: Protecting two phases of fan motors or control elements in commercial/industrial systems.
Applications needing Curve 2: Suitable for circuits with equipment having moderate start-up surges (e.g., some types of power supplies, resistive loads, general lighting).
Application Voltage: Specifically for 415 Vac Line-to-Line applications requiring 2-pole protection.
Curve Selection: Curve 2 (Medium Delay) is suitable for general purpose loads; use Curve 1 (Long Delay) for higher inrush loads like transformers or certain motors if available in this configuration.
Interrupting Capacity: Ensure the 6kA rating is adequate for the calculated prospective short circuit current at the point of installation.
Mounting Flexibility: The Dual Mount feature allows installation on either standard 35mm DIN rail or Mini Rail systems.
Wiring & Torque: Connect L1 and L2. Use appropriate wire gauge (0.75-25mm² IEC) and torque terminals to 2.5 Nm (IEC).
Temperature Independence: Rely on consistent performance in varying temperature conditions.
Isolation: Provides a reliable double-pole isolation point for maintenance.
