1 / 7Circuit Breaker
MCB 1P DC 6鈥?3A Circuit Breaker
The Cnsoltree 1 Pole DC MCB is the most space-efficient solution for protecting individual photovoltaic strings and single-line DC branch circuits. At just 18mm wide, it fits where multi-pole breakers cannot 鈥?making it the go-to choice for densely packed combiner boxes and compact off-grid battery enclosures. Rated at 500V DC with enhanced magnetic arc quenching, this breaker reliably interrupts stubborn DC arcs that would damage conventional AC-rated devices. Every unit leaves our ISO 9001 certified factory only after passing 100% electrical verification, giving installers confidence in consistent trip accuracy across the full 6鈥?3A range. Whether you are wiring a rooftop solar array, a 48V telecom rack, or an RV leisure battery, the 1P DC MCB delivers code-compliant overcurrent protection without wasting valuable panel space.
Key Features
- Ultra-compact 18mm single-module width 鈥?saves critical DIN-rail space in crowded combiner boxes.
- 500V DC arc-quenching chamber 鈥?safely extinguishes persistent DC arcs that standard AC breakers cannot handle.
- 9 current ratings (6A鈥?3A) 鈥?one SKU family covers everything from small off-grid setups to large string inverters.
- 100% factory electrical testing 鈥?every unit verified for correct trip curve before shipment.
- Full OEM/ODM program 鈥?custom printing, private-label packaging, and modified trip curves available.
- Thermal-magnetic dual protection 鈥?fast short-circuit response plus reliable overload tripping.
- Snap-on 35mm DIN rail mount 鈥?tool-free installation and removal for rapid field service.
