MCB 25 Amp DC Mini Circuit Breaker 2 Pole

📝 25A DC mini circuit breaker – 2 pole DIN rail

The 25A DC mini circuit breaker (2 pole) is designed to protect 12v, 24v, and high-voltage DC electrical systems from overloads and short circuits. When current exceeds safe levels, the breaker automatically trips to prevent damage to wiring, batteries, and connected equipment.

With its compact DIN rail mount design, this breaker is ideal for caravan, campervan, RV, solar, and off-grid electrical installations. The dual pole switching isolates both positive and negative lines for safer and more complete circuit protection.

⭐ Essential benefits

• Dual pole protection – isolates both positive and negative circuits for improved safety
• Reliable overload protection – automatically trips to protect wiring and equipment
• Manual reset operation – quickly restore power once the fault is cleared
• DIN rail mounting – simple installation in electrical distribution boxes
• Compact design – ideal for caravan, solar, and off-grid installations

This breaker delivers dependable circuit protection while keeping electrical panels organised and secure.

⚙️ Functionality

The breaker continuously monitors the current flowing through the circuit. If the load exceeds 25 amps, the breaker automatically trips and disconnects power to protect wiring and electrical equipment.

After the fault is resolved, the breaker can be manually reset using the switch lever, restoring power to the circuit.
