⎯⎯ Applications
Where VIOX RCCBs Are Used
EV Charging
Charging Infrastructure
Type F and EV-oriented variants align with modern charging environments that require more than basic AC-only residual-current protection.
EV Charging
Charging Infrastructure
Type B and B+ product families support installations where residual-current behavior is shaped by converters, drives, and power electronics.
Industrial
Drives and Power Electronics
Type A RCCBs fit distribution-board applications across commercial facilities, offices, retail spaces, and public-use systems.
Solar
PV and Storage Projects
Type B product lines align with inverter-based environments where DC-related residual-current conditions must be considered.
Residential
Home Safety Protection
RCCBs are widely used in residential distribution boards where earth-leakage protection is part of the protective architecture.
Distribution Partners
Structured Product Programs
Multi-type RCCB coverage supports catalog programs that need a coherent product family rather than isolated single-series supply.
⎯⎯ Selection
How To Choose the Right RCCB
STEPS
- Match the RCCB type to the actual load behavior and residual-current waveform conditions.
- Confirm the pole configuration required by the system layout.
- Review the rated current against the installation design.
- Select the correct sensitivity level for the protection objective.
- Check standards context and technical requirements for the target market or project.
TIPS
| Selection Factor | Why It Matters | Common Mistake |
|---|---|---|
| RCCB Type | Determines waveform and application compatibility | Choosing by current rating only |
| Sensitivity | Defines leakage-detection threshold | Using one value for every circuit |
| Pole Configuration | Must match the circuit arrangement | Selecting the wrong installation format |
| Rated Current | Must align with the protected system | Treating all RCCBs as interchangeable |
| Application Fit | EV, PV, drives, and standard boards do not require the same device type | Using basic types in complex electronic environments |
⎯⎯ FAQ
Frequently Asked Questions
What does an RCCB protect against?
An RCCB detects leakage current and disconnects the circuit when residual-current imbalance is detected.
What is the difference between Type A, Type F, and Type B RCCB?
The difference is mainly in the type of residual-current waveform and application environment the device is designed to handle.
Where are RCCBs commonly used?
They are commonly used in residential distribution boards, commercial systems, EV charging, PV systems, and installations with electronic loads.
What current range does the VIOX RCCB lineup cover?
The current live RCCB lineup highlights series covering rated currents from 16A to 100A, depending on model family and type.
How do I choose the right RCCB type?
Choose the RCCB type according to the load characteristics, residual-current behavior, application environment, and project requirements.
