MCCB 2P 125A Breaker for DC Photovoltaic Systems
This 2P MCCB circuit breaker is specially designed for the protection of photovoltaic systems, storage batteries, and 1000V DC installations. It acts as an automatic barrier against short circuits, overloads, and overvoltages, instantly interrupting the circuit upon fault detection. Ideal for installation between the battery bank and the inverter, it ensures the safety of the entire solar installation.
What you get with this product
- Automatic protection against short circuits and overloads — instantaneous interruption upon fault detection, no manual intervention required
- Resistance to extreme temperatures between -20°C and +60°C — operates smoothly in uninsulated warehouses or outdoor installations
- High-quality flame-retardant ABS housing — carbonizes upon contact with open flame without sustaining combustion
- Simple manual switching via ON/OFF lever — you can quickly disconnect the circuit for maintenance or emergency interventions
- Compatible with high-power photovoltaic systems — 125A capacity at 1000V DC, suitable for residential and commercial installations
- Standard DIN rail mounting — easily integrates into existing electrical panels, without structural modifications
How it works and how to install it
The MCCB continuously monitors the current flowing through the circuit. Upon detecting an overload, short circuit, or overvoltage, the internal mechanism automatically interrupts the power flow within milliseconds. Installation is done by mounting on a DIN rail in the electrical panel, connecting the two poles to the DC circuit that requires protection — typically between the battery bank and the inverter. Connections are made via the upper and lower screw terminals, ensuring stable electrical contact.
Frequently asked questions
Can it be used to protect 220V electrical circuits in the house?
No, this breaker is designed exclusively for DC current. For 220V AC alternative circuits, dedicated AC breakers must be used.
How quickly does the breaker intervene in case of a short circuit?
The interruption is instantaneous, occurring within milliseconds of fault detection, efficiently protecting connected equipment.
Can it be reset after it has tripped automatically?
Yes, after remedying the problem that caused the trip, you can manually reset the breaker by moving the lever from the OFF position back to ON.
