VKL11 Type A EV 2P Residual Current Circuit Breaker (RCCB) Dimension
Understanding the VKL11 RCCB’s Unique Functionality
The VKL11 RCCB is not an ordinary residual current device. Specifically developed for Mode 3 EV charging applications, it provides specialized protection capabilities that standard RCCBs cannot offer. Let’s explore the distinctive features that make the VKL11 an integral component in modern electrical safety systems.
Type A Classification with Enhanced DC Protection
While conventional Type A RCCBs can detect both AC sinusoidal and pulsed DC residual currents, the VKL11 adds an additional layer of protection with its 6mA smooth DC detection capability. This enhanced functionality is crucial for EV charging systems, where DC leakage can occur due to the rectification components in charging equipment.
The VKL11 continuously monitors the electrical circuit for:
- AC sinusoidal residual currents (30mA – 50Hz)
- Pulsating DC residual currents
- Smooth DC residual currents (6mA)
This comprehensive monitoring ensures maximum safety for both users and equipment in EV charging environments, where the risk of DC leakage is significantly higher than in standard electrical installations.
Instantaneous Tripping Mechanism
Safety in electrical systems is measured in milliseconds. The VKL11 RCCB features an instantaneous tripping mechanism that activates without time-delay when a fault is detected. This rapid response is critical in preventing electrical accidents, particularly in EV charging scenarios where high currents are involved.
The tripping time under I∆n is ≤ 100ms, ensuring immediate circuit isolation when leakage currents exceed the threshold. This instantaneous protection is essential for safeguarding both users and valuable electrical equipment from potential damage.
