Working Principle & Features
The C65N-DC series is a circuit breaker dedicated to DC systems, featuring the following characteristics:
- Sistema di estinzione dell'arco: 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).
- Caratteristiche di intervento:
– 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) e protezione da cortocircuito (magnetic protection).
- Caratteristiche strutturali:
– Compact design with a depth of only 68mm, saving installation space.
– Mechanical service life of up to 20,000 operazioni, ensuring high reliability.
– Protection class IP20 (for the unit itself) / IP40 (when installed in distribution boxes), providing dust and electric shock protection.
Scenari applicativi
This circuit breaker is suitable for various DC power supply systems:
Industrial Automation: DC motor control, PLC control systems.
New Energy Sector: Solar inverter output protection, sistemi di accumulo dell’energia.
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, ecc.
Selection & Note sull'utilizzo
- Corrispondenza della tensione: Must be used with 125V DC systems; not applicable for AC systems.
- Current Selection:
– The rated current (6UN) should be greater than the maximum operating current of the circuit.
– Consider load starting current: Type C curve allows short-term overloads (per esempio., 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, protezione da cortocircuito, and circuit control functions, it is particularly suitable for protecting loads below 6A in 125V DC systems.
