A Type 2P RCCB

As a professional factory in China, XENHO produces A Type 2P RCCB for AC and pulsating DC leakage protection, tripping within 0.1s. This manufacturer‑built device supports 630–6300A, 3P/4P, electronic/thermal‑magnetic release.

What is a Type A 2P RCCB?

The A Type 2P RCCB is a 2-pole residual current protection device equipped with overload and short-circuit protection functions. It continuously monitors the residual current within the circuit and automatically interrupts the power supply when the leakage current reaches its rated tripping current (e.g., 30mA, 100mA, or 300mA), thereby preventing electric shock accidents and mitigating the risk of electrical fires.

Product Parameters

Loading and Shipping

The A Type 2P RCCB is packaged in standardized export-grade wooden crates, each lined with shock-absorbing and moisture-proof film to ensure safe transit over long distances. We support multimodal transport—including sea, air, and rail freight—and provide comprehensive end-to-end services covering customs clearance and commercial inspection. Prior to delivery, a thorough performance re-inspection is conducted; the shipment is accompanied by a factory inspection report, a product certificate of conformity, and a detailed installation and operation manual.

FAQ

1. Q: What is the rated current range for the Type A 2P RCCB? Is it possible to customize different specifications?

A: The standard rated current range for the Type A 2P RCCB covers 16A to 125A; specific models can be selected based on actual power distribution requirements. For current specifications required in specialized scenarios, XENHO supports customized production within a certain scope; specific parameters and certification requirements must be discussed with our technical support team prior to order confirmation.

2. Q: What is the tripping time for this product? Can it meet the safety requirements for rapidly interrupting faults?

A: The product strictly adheres to the IEC 61008 standard. At its rated tripping current, the disconnection time is ≤0.1 seconds (for the 30mA rated tripping current specification), ensuring that the power supply is cut off rapidly in the event of a leakage fault to minimize the risk of electric shock injury. For specifications with higher rated tripping currents (e.g., 300mA), the disconnection time is ≤0.3 seconds, striking a balance between personal safety and equipment protection.

3. Q: What environmental factors should be considered during installation? Is professional installation required?

A: During installation, ensure that the ambient temperature remains between -25°C and +60°C, the relative humidity is ≤95% (non-condensing), and the device is kept away from severe vibrations, corrosive gases, and strong magnetic fields. Although the product features a modular design to facilitate installation, electrical safety regulations mandate that wiring and commissioning be performed by a qualified professional electrician. After installation, the effectiveness of the leakage protection function must be verified using the leakage test button.

4. Q: What is the product's service life? What routine maintenance is required?

A: The Type A 2P RCCB boasts an electrical life of ≥10,000 rated tripping operations and a mechanical life of ≥20,000 operating cycles, allowing it to meet operational demands for over 10 years under normal usage conditions. For routine maintenance, it is recommended to press the test button (TEST key) quarterly to verify that the leakage protection function is operating correctly. Additionally, an insulation resistance test should be performed annually by a professional (using a 500V megohmmeter; the insulation resistance should be ≥100MΩ). If the test button fails to respond or if abnormal heat is detected, the device must be immediately taken out of service, and our after-sales support team should be contacted for a replacement.
