These types are capable of sensing pulsating residual currents and are not negatively affected by a DC overlay of up to 6mA. ​ ​These devices (depending on the range) are also available as:​ -G/A short time delayed devices which are surge current proof up to 3kA. These devices enable a reliable and safe installation with increased system availability​ -S/A selective RCCBs with improved surge current capabilities up to 5kA. These devices are selective (conditions apply) to other RCDs and enable special applications and root installations.​

The xEffect range of protective switchgear also ensures highest standards of safety in railway applications. Thanks to compliance with specific standards such as IEC 61373 (Rolling stock equipment – Shock and vibration) and EN 45545-2 (fire protection of railway vehicles), the devices provide maximum safety and performance in rolling stock applications. In addition to standard switchgear, we also offer a wide range of MCBs and RCDs for the connection of ring cable lugs in railway applications.
