Working Principle & คุณสมบัติ
The C65N-DC series is a circuit breaker dedicated to DC systems, featuring the following characteristics:
- Arc Extinguishing System: Equipped with a special arc extinguishing device designed specifically for DC circuits, effectively quenching DC arcs (DC arcs are more difficult to extinguish than AC arcs).
- Tripping Characteristics:
– Type C Curve: Suitable for protection of general loads and distribution lines, with an instantaneous tripping current of approximately 51A (8.5×6A).
– Thermal-Magnetic Tripping: Integrates dual protection functions of overload protection (thermal protection) and short-circuit protection (magnetic protection).
- Structural Features:
– Compact design with a depth of only 68mm, saving installation space.
– Mechanical service life of up to 20,000 operations, ensuring high reliability.
– Protection class IP20 (for the unit itself) / IP40 (when installed in distribution boxes), providing dust and electric shock protection.
สถานการณ์การใช้งาน
This circuit breaker is suitable for various DC power supply systems:
ระบบอัตโนมัติทางอุตสาหกรรม: DC motor control, PLC control systems.
New Energy Sector: Solar inverter output protection, energy storage systems.
Communication Equipment: DC-powered devices such as base stations and switches.
Rail Transit: Vehicle auxiliary power supply systems.
Marine Electrical Systems: DC distribution systems.
Typical Application: Protecting DC loads below 6A, such as sensors, small controllers, communication modules, ฯลฯ.
Selection & Usage Notes
- การจับคู่แรงดันไฟฟ้า: Must be used with 125V DC systems; not applicable for AC systems.
- Current Selection:
– The rated current (6ก) should be greater than the maximum operating current of the circuit.
– Consider load starting current: Type C curve allows short-term overloads (เช่น, motor startup).
- Pole Number Selection: The 2P structure disconnects both positive and negative poles simultaneously, providing safer circuit isolation.
C65N-DC/2P-C6A is a compact protection device developed by Schneider for DC systems. Integrating overload protection, ป้องกันการลัดวงจร, and circuit control functions, it is particularly suitable for protecting loads below 6A in 125V DC systems.
