A 25A DC circuit breaker (circuit breaker) for PV systems is an essential protection device specially designed to handle the direct current generated by solar panels.
Here are the main features and functions of this model:
- Dual Protection: Provides overload (when consumption exceeds capacity) and short circuit protection, preventing inverter or wiring damage.
- 2-DC (Bipolar) Configuration: Interrupts both (+ and -) wires of the circuit simultaneously, providing complete isolation and increased safety during maintenance.
- Breaking Capacity: It is built to extinguish the electric arc specific to the direct current, much more dangerous than the alternating one, thus protecting the system against fires.
- Installation: It is usually installed on the DIN rail in the electrical panel (string box), between the photovoltaic panels and the inverter or between the batteries and the charge controller.
- Durability: The housing is made of flame retardant materials, resistant to high temperatures, being optimized for long operation in renewable energy systems.
