Introduce

HYCA is a Leakage Protection Residual Current sensor specifically developed for EV-charging providing all-current sensitivity.

Charging of electric vehicles at a standard wall socket or a wall box requires protection devices against DC fault currents to avoid

avoid electric shock. Installed type A residual current circuit-breakers (RCCBs) are unable to identify and deactivate DC fault currents.

 

 

Advantages

  • Small volume and footprint for integrationinto compactIC-CPD
  • Avoidshazardous situations withDC fault currents · Protects RCCB type A from saturation

 

 

Saves costly type B RCCD

Volume optimized

  • AC/DC-current sensitivity atlow cost· Protects RCCB type A from saturation · Self-monitoring and test functions
  • Robustmechanical design suitable for IC-CPD

 

 

Features

Fault current detection according to IEC 62752 or UL 2231

Frequency range DC up to 2 KHz

  • Load currentup to 80 Arms (1-phase) or 3 x 32 Arms (3-phase)    · Switching output for 6 mA DC and 30 mA AC (acc. to IEC 62752)
  • Integrated self-monitoring and test functions· Measurement resolution of 0.2 mA

Variants with pass through opening or with integrated primary conductors

Differential current range 0~300 mA

  • Robustmechanical design suitable for IC-CPD environmental requirements (e.g. drop test) · Widely usable in harsh electronic environment (e.g. resistant to external magnetic fields)
  • The sensor can trigger an automatic shut-off incaseof hazardous electrical faults (DC and AC) according to IEC 62752 or UL2231.

 

Standard

1.Meet IEC 62752 mode 2 charging-related residual current test requirements.

2.Meet IEC 62955 mode 3 charging RDC-PD related residual current test requirements.

3.Meet the basic requirements of GB/T 22794 based on the adaptation of DC 6mA test requirements.
