DC Circuit Breaker
Poles: 2-pole (2P) – disconnects both positive and negative lines or two phases of a DC circuit
Current Rating: 250 Amperes
Voltage Rating: Commonly ranges from DC 250V to 1000V (depending on model)
Application: Protection of high-current DC circuits, often used in:
Solar PV systems
Battery storage systems
Electric vehicle charging stations
Industrial DC distribution panels
-
Typical Features:
High breaking capacity for safely interrupting large DC fault currents
Arc extinguishing design to handle DC arcs
Thermal-magnetic or electronic trip unit for overload and short-circuit protection
DIN rail mounting (in modular models) or panel mounting
