DC MCCB 125A 550V PV Solar Molded Case Circuit Breaker

DC MCCB 125A 550V PV Solar Molded Case Circuit Breaker is a device used in solar power generation systems to protect circuits from overload and short circuit damage.

DC MCCB 125A 550V PV Solar Molded Case Circuit Breaker It is specifically designed for use with DC (direct current) photovoltaic (PV) systems, which are the type of solar panels that most homeowners and businesses use.

DC MCCB 125A 550V features;

• Rated current: 125 amps
• Rated voltage: 550 volts DC
• Number of poles: 2 or 3 (2 poles for single-phase circuits, 3 poles for three-phase circuits)
• Interrupting capacity: The maximum amount of current that the circuit breaker can safely interrupt. This is typically 10,000 to 50,000 amps for DC MCCBs.
• Trip curve: The time-current characteristic of the circuit breaker. This determines how quickly the circuit breaker will trip in response to an overload or short circuit.
• Standards compliance: The circuit breaker should be certified to meet relevant safety standards, such as UL 489B for DC molded-case circuit breakers.
