250A MCCB Circuit Breaker for DC Photovoltaic Systems
This 2P MCCB circuit breaker protects solar installations and storage batteries against overload, short-circuit, and overvoltage. Specifically designed for voltages up to 1000V DC, it ensures rapid automatic interruption in case of a fault, maintaining the safety of the photovoltaic system and extending the lifespan of the equipment.
What you get with this product
- Complete automatic protection for inverters and batteries — instant interruption upon detection of short circuit or overload
- Compatibility with high-capacity photovoltaic systems — supports a rated current of 250A and voltage up to 1000V DC
- Self-carbonizing flame-retardant ABS casing — does not sustain flame and does not propagate combustion in case of an incident
- Stable operation in extreme conditions — resistant to temperatures between -20°C and +60°C, ideal for outdoor mounting
- Simple operation via manual ON/OFF switch — visible control and quick access to disconnection when needed
- Quickly mounted on standard DIN rail — no modifications to the existing electrical panel required
How it works and how to install it
The MCCB circuit breaker is installed between the battery bank and the inverter, providing bilateral protection. It is fixed on the DIN rail in the electrical panel using the included side brackets. Connections are made via the upper and lower terminals, using conductors suitable for 250A. In case of overload or short circuit, the automatic mechanism instantly trips the circuit, and the signaling LED indicates the operating status.
Frequently asked questions
Can I use this circuit breaker for my home's electrical installation?
No. This MCCB is designed exclusively for direct current (DC) circuits in photovoltaic systems, electric charging stations, or storage batteries. A different type of protection is required for domestic AC circuits.
What is the maximum current it supports before automatically tripping?
The circuit breaker is calibrated for a rated current of 250A. If this threshold is exceeded or in case of a short circuit, the thermal and electromagnetic mechanism instantly trips the circuit to protect the connected equipment.
Can it be mounted directly on the solar panel or does it need to be in the panel?
It is mounted inside the electrical panel on a standard DIN rail, not directly on the panels. It is designed for the protection of circuits between batteries and the inverter, in an environment protected from direct moisture.
