Residual current sensors for electromobility
Standards-compliant safety for charging infrastructure
Our residual current sensors were specifically developed for use in electromobility. They ensure reliable and standards-compliant detection of AC, DC, and mixed residual currents in charging equipment for electric vehicles – both in stationary wallboxes and in mobile charging units and on-board systems.
Technical features and benefits
- Reliable detection of AC and DC fault currents
- Fast response times for maximum protection
- High measurement accuracy across the specified temperature range
- Compact design for space-optimized integration
- Robust design for industrial and automotive environments
- Compliant with global regulatory requirements
Through precise differential current measurement, our sensors make a significant contribution to electrical safety, personal protection and system availability.
Standard-compliant residual current detection
Our sensor solutions meet the requirements of internationally relevant standards:
- IEC62752 – In-Cable Control and Protection Device (IC-CPD)
- IEC62955 – Residual current protective devices for EV charging equipment
- UL2231-2 – Personnel Protection Systems for North America
This makes our sensors suitable for worldwide use in AC charging equipment in accordance with international safety requirements.
