Single Phase EMC Filter – 12Amp, Block HLE Series

The Block HLE 310 series is a high-performance single-phase EMC filter designed to reduce electromagnetic interference (EMI) between electrical equipment and the mains power supply. It helps ensure compliance with EMC regulations while improving system reliability and reducing unwanted electrical noise in sensitive electrical and electronic applications.

This filter is suitable for single-phase variable speed drives, inverters, automation equipment, and other power electronic devices where conducted interference must be effectively controlled. It can be used as a standalone solution or in systems with existing internal EMC filtering.

The HLE 310 series features a low leakage current design, making it particularly suitable for installations where residual current devices (RCDs) are in use or where multiple filtered devices are connected on the same supply.

For many applications, internal EMC filtering may be sufficient; however, where stricter EMC requirements apply, an external filter such as the HLE series can be added to further reduce interference.

For best performance, the filter should be correctly matched to the application and installed as close as possible to the source of interference.

Key Benefits

• Reduces conducted electromagnetic interference (EMI)
• Helps achieve EMC compliance in single-phase systems
• Low leakage current – suitable for RCD-protected installations
• Improves system stability and reliability
• Suitable for VFDs, inverters, and automation equipment
• Can be used with or without internal drive filters

This variant of the HLE 310 series EMC filter is rated at 12A, and is suitable for single phase applications with corresponding load requirements.
