The PQB1Z-63 4P 1000V DC Solar Miniature Circuit Breaker is a supplementary protector engineered for overcurrent protection in solar photovoltaic systems. This 4-pole breaker handles up to 1000V DC, with current ratings available from 1A to 63A, and is designed for 35mm DIN rail installation. It integrates a thermoplastic housing with copper conductors and silver alloy contact points, ensuring durability in high-voltage DC environments typical of utility-scale and residential solar arrays.
The device complies with IEC/EN60947 standards and offers breaking capacities of 6kA or 10kA, depending on the model. Its characteristic curves (B, C, D) cater to different load types, while the IP20 protection degree shields against solid objects larger than 12mm. Mechanical life exceeds 20000 cycles, and electrical life surpasses 8000 operations, making it suitable for long-term use in renewable energy infrastructure. Standard industry tolerances for DC breakers include voltage stability within ±5% and temperature operation ranges of -20°C to +60°C for similar devices.
This breaker is primarily used in solar panel arrays, inverters, and wiring systems to prevent overcurrent damage. Buyers typically include solar farm developers, electrical contractors, and OEMs in the renewable energy sector. The unit’s dimensions scale with pole count: 18x80x71mm for 1P, up to 72x80x71mm for 4P. Confirm compatibility with your system’s voltage, current, and DIN rail specifications before ordering, as accessories like auxiliary contacts may be available.

Before ordering, verify the breaker’s voltage and current ratings match your solar system’s requirements. Check compatibility with your existing DIN rail setup, as the 4P model requires 72mm width. Confirm whether the characteristic curve (B, C, or D) aligns with your load type to avoid nuisance tripping or inadequate protection.
Discuss logistics with the supplier to clarify lead times, as these are not specified. Standard Incoterms for electrical components often include FOB or CIF, but confirm which applies to your shipment. Payment terms may vary, so request options like TT (Telegraphic Transfer) or LC (Letter of Credit) and ensure they align with your procurement policies.
Quality checks should include visual inspection for housing integrity and contact point condition. Test the breaker’s electrical life by simulating operations under load, and verify the IP20 rating suffices for your environment. Request a certificate of compliance with IEC/EN60947 and any additional documentation, such as test reports for breaking capacity, to ensure the product meets your standards.
