PXL9-63 Series Electromagnetic Leakage Circuit Breaker
The PXL9-63 is specified for residual-current protection without overcurrent protection. Select it using the published voltage, current, pole and protection data, then confirm conductor coordination, fault conditions, enclosure requirements and local installation rules.
Product Overview
PXL9-63 is a 63A RCCB for AC 230/400V applications. It is intended for residential, commercial and industrial circuits where a separate overcurrent device is coordinated; this describes an evaluation context, not a universal approval. Confirm the complete circuit design before specifying the product.
residual-current protection without overcurrent protection is distinct from adjacent protection functions. Do not infer AC/DC suitability, residual-current protection, automatic control or isolation performance from the product family name alone.
Key Features
Typical Applications
residential, commercial and industrial circuits where a separate overcurrent device is coordinated. Verify system voltage, expected fault current or leakage, wiring arrangement, environment, coordination and applicable rules for the ordered configuration.
Applications and Selection Guide
Use the verified PXL9-63 records below to create a shortlist. Product labels do not replace the project calculation, coordination review or exact installation instructions.

| Fault / residual data | 30mA, 100mA or 300mA options | Prospective short-circuit or leakage conditions |
RCCB vs RCBO
An RCCB addresses residual-current protection; an RCBO combines residual-current and overcurrent functions. Choose the architecture required by the protection study.

PXL9-63 Product FAQ
What is the PXL9-63 used for?
The PXL9-63 is specified for residual-current protection without overcurrent protection in AC 230/400V applications, within the ratings and configurations listed in its technical table. Final suitability depends on the complete circuit design.
How does the PXL9-63 work?
Its operating principle follows the documented function: residual-current protection without overcurrent protection. Use the exact model documentation for thresholds, timing, trip behaviour, terminals and test procedures.
How do I choose the PXL9-63 rating and poles?
Start with the design current and system arrangement, then choose only a published option. The page lists pole options as 2P / 4P; confirm neutral, polarity, conductors and isolation requirements.
What safety limitation applies to the PXL9-63?
Do not treat the PXL9-63 as a universal substitute for another device. Confirm 30mA, 100mA or 300mA options, the system voltage, fault or leakage conditions and any separate upstream protection before selection.
Can the PXL9-63 be used in another circuit type?
Only when the exact ordered configuration is rated for that circuit. AC and DC duties, residual-current devices, isolators, smart controls and voltage protectors are not interchangeable by appearance or current rating.
How should the PXL9-63 be installed and tested?
Use the exact product drawing, terminal identification and instructions. A qualified person should verify isolation, conductors, torque, settings, coordination and functional tests before energising the circuit.
