DZ47LE-63 Residual Current Circuit Breaker 1-4 Pole with CE Certificate for Electrical Safety

Breaking capacity is tested at 6kA during our routine batch validation, and we run a full IEC1009-1 compliance check on every production run—not just random sampling—so you can rely on consistent performence across all 63A-rated poles form 1+N through 4-pole configurations.

We hold CE, CB, and CCC certificates for the DZ47LE-63, but what that means in practice is each unit undergoes a 100% operational test for overload, short circuit, and earth leakage before it leaves line, and we maintain a retest policy if any batch shows even one failure in the 20,000-cycle mechanical life test.

Flame-retardant PA66 case material is standard, but we also verify arc-extinguishing air gap integrity under 30°C operating conditions; the 10mm² wiring capacity is actually tighter than most similar breakers, which matters when you're running 63A continuous load.

Ordering is straightforward—you'll specify pole count and current rating (6A through 63A), and we usually have stock for 1+N and 4-pole variants within 20 days or so, though OEM/ODM customizations like over-voltage protection add about 2-3 weeks lead time.

We don't test for every possible fault scenario—like sustained 50Hz harmonic distortion above 5%—so if your application involves heavy variable frequency drives, you might want to confirm compatibilty before ordering 1000 units or more.

Basically, the batch consistency comes from our in-house HPLC-grade monitoring on leakage current thresholds, and we'll retest any lot free of charge if your incoming COA doesn't match our posted specs within ±0.5% tolerance.
