動作原理 & 特徴
The C65N-DC series is a circuit breaker dedicated to DC systems, featuring the following characteristics:
- アーク消火システム: 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).
- トリップ特性:
– タイプ C 曲線: 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 (熱保護) および短絡保護 (磁気保護).
- 構造上の特徴:
– Compact design with a depth of only 68mm, 設置スペースの節約.
– Mechanical service life of up to 20,000 オペレーション, ensuring high reliability.
– Protection class IP20 (for the unit itself) / IP40 (配電ボックスに設置する場合), providing dust and electric shock protection.
アプリケーションシナリオ
This circuit breaker is suitable for various DC power supply systems:
産業オートメーション: DC motor control, PLC制御システム.
New Energy Sector: Solar inverter output protection, エネルギー貯蔵システム.
Communication Equipment: DC-powered devices such as base stations and switches.
Rail Transit: Vehicle auxiliary power supply systems.
船舶用電気システム: DC distribution systems.
代表的な用途: Protecting DC loads below 6A, such as sensors, small controllers, 通信モジュール, 等.
選択 & 使用上の注意
- 電圧マッチング: Must be used with 125V DC systems; not applicable for AC systems.
- 現在の選択内容:
– The rated current (6あ) should be greater than the maximum operating current of the circuit.
– Consider load starting current: Type C curve allows short-term overloads (例えば, motor startup).
- 極数の選択: 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, 短絡保護, and circuit control functions, it is particularly suitable for protecting loads below 6A in 125V DC systems.
