Cores For Leakage Circuit Breakers
This nanocrystalline magnetic core is designed specifically for residual current circuit breakers (RCCBs), ground fault circuit interrupters (GFCIs), and industrial earth leakage protection systems. It uses a Fe-based nanocrystalline soft magnetic alloy to deliver high initial permeability and low core loss, ensuring reliable tripping protection under high-current conditions. The core operates across a temperature range of -55 to 130°C, maintaining stability for consistent performance in demanding environments.
The material composition and engineering enable significant size reduction without compromising output voltage or current impulse tolerance. Typical applications include OEM circuit breaker assemblies where IEC 61008 compliance is required. Nanocrystalline cores in this category often exhibit permeability values in the range of 80,000 to 140,000, with saturation induction around 1.2T, though exact figures for this model should be confirmed with the supplier.
Manufacturers of leakage circuit breakers source these cores to improve protection accuracy and reduce false tripping. The component is suited for industrial panels, residential distributions, and commercial electrical systems where precise fault detection is critical. Buyers should verify compatibility with their specific breaker designs and confirm the core’s performance under their intended load conditions.

| Operating Temperature Range | -55°C to 130°C |
| Temperature Stability | Good, maintains performance across full range |
| Current Impulse Tolerance | High, designed for large current impulses |
| Output Voltage | High (exact value depends on winding and application) |
| Application Compliance | IEC 61008 (for RCCB/GFCI use) |
| Core Size Reduction | Enabled by high permeability, exact dimensions supplier-specific |
| Typical Packaging | Standard export packaging for magnetic components (confirm with supplier) |

Sourcing Cores For Leakage Circuit Breakers from Long Line Electronic Company Limited - China Import Guide
Before ordering, verify that the cores meet the exact permeability, core loss, and temperature stability requirements of your leakage circuit breaker design. Request the supplier’s datasheet and third-party test reports to confirm compliance with IEC 61008 or other relevant standards for your target markets.
Confirm logistics details such as lead time, which can vary based on custom specifications, and packaging standards to prevent damage during transit. Incoterms should be agreed upon explicitly, with FOB or CIF commonly used for magnetic components shipped from China. Payment terms typically include a deposit with the balance due before shipment, but this should be negotiated directly.
Quality checks should include dimensional verification, core loss testing at your application’s operating frequency, and thermal cycling to ensure stability. Inspect the cores for physical defects or inconsistencies in coating, if applicable, and request certificates of conformance for the material composition and magnetic properties. Documentation such as material test reports and compliance certificates is essential for traceability.
