DC12~1000V 63~125A 1P/2P/3P/4P Molded Case Circuit Breaker MCCB

1. MCCB Specifically Designed for PV and Battery Applications
1P/2P/3P/4P DC MCCBs provide reliable overload, short-circuit protection, and isolation functions for PV systems with rated DC voltages of 12-1000V and rated currents of 63A/80A/100A/125A, featuring a breaking capacity up to 20kA
2. Flame-Retardant Housing with Silver Contacts
The resin enclosure offers high insulation and exceptional flame-retardant properties. Internal conductive components feature silver contacts for low resistance and minimal heat generation
3. Thermal-Magnetic Trip and Non-Polar Design
Precision thermal-magnetic trip technology combined with enhanced DC arc extinction capability ensures safe and reliable disconnection at combiner boxes and inverter inputs. Non-polar wiring and space-saving design enable seamless integration with PV modules
4. DC MCCB Applications
CNLONQ DC molded case circuit breakers serve as essential protective components in PV systems, widely deployed at critical junctions including PV strings, combiner boxes, inverter inputs, and battery energy storage systems
5. EU Certification and Professional MCCB Manufacturer
CNLONQ provides R&D, production, and quality inspection for a full range of molded case circuit breakers. MCCBs are CE, ISO, and GTS certified, compliant with IEC 60947-2 standards

Why do you need a CNLONQ PV Combiner Box for your PV system?

A PV system needs a specialized MCCB like CNLonQom to safely interrupt high-voltage DC power, which is far more hazardous than AC, by effectively quenching dangerous electrical arcs. It provides critical protection for system components against overloads and short circuits, ensures reliable isolation for maintenance, and guarantees compliance with international safety standards.
