🛡️ Overload & Short-Circuit Protection

The breaker disconnects the circuit when current rises beyond safe operating levels, helping protect:

• Solar cables
• PV equipment
• Inverters
• Controllers
• Connected DC devices

Its 6kA breaking capacity allows it to safely interrupt high fault currents within its rated limits.

⚙️ 2-Pole DC Isolation

The dual-pole design disconnects both sides of the DC circuit simultaneously, making it particularly suitable for photovoltaic installations where proper DC isolation is important.
