VKL11F Typ F EV 2P Zbytkový proudový jistič (RCCB)

The VKL11F Residual Current Circuit Breaker Type F EV represents the cutting edge in electrical safety technology specifically engineered for electric vehicle (EV) charging applications. As the electric vehicle market continues to expand, ensuring safe and reliable charging infrastructure becomes increasingly critical. The VKL11F RCCB stands as an essential safety component that protects both your valuable electrical systems and the people who interact with them.

What is the VKL11F RCCB Type F EV?

The VKL11F is a specialized Residual Current Circuit Breaker (RCCB) that has been specifically developed to address the unique electrical protection requirements in EV charging environments. This device monitors electrical circuits for imbalances and automatically disconnects the circuit when a potentially dangerous situation is detected, preventing electrical shocks and fires.

Unlike standard RCCBs, the VKL11F Type F EV is designed to detect and respond to both AC and DC residual currents, making it particularly suited for the complex electrical environments associated with modern electric vehicle charging systems. It meets and exceeds the stringent requirements of EN61008-1 and EN62423 standards, ensuring maximum safety and reliability.

Key Features of the VKL11F RCCB

Specialized EV Charging Protection

The VKL11F Type F EV RCCB has been meticulously engineered for electric vehicle charging systems. It can detect both AC and DC residual currents in accordance with EN61008-1 and EN62423 standards, providing comprehensive protection specifically tailored for EV charging stations.

Mixed Frequency Detection

One of the standout features of the VKL11F RCCB is its ability to detect residual currents with mixed frequencies, which differentiates it from standard 50Hz protection devices. This capability is crucial in EV charging applications, where power electronics can generate currents at various frequencies.

Enhanced Surge Current Strength

The VKL11F RCCB features short-time delayed operation and increased surge current strength, significantly reducing the risk of false tripping. This ensures reliable operation even in challenging electrical environments commonly found in EV charging setups.

Multiple Tripping Sensitivity Options

With tripping sensitivity of 30mA for sinusoidal AC currents and pulsating DC, as well as 6mA for smooth DC (RDC-PD), the VKL11F provides comprehensive protection against various types of fault currents that may occur in EV charging circuits.
