Product catalog summary
Overview: The BRCM01C is an AC/DC residual current monitor designed for electric vehicle (EV) charging equipment. It supports Type-A 30 mA and/or DC 6 mA monitoring, compliant with IEC 62955, IEC 62752, IEC 61008-1, and IEC 60947-2 standards. It features a 12V DC interface for integration with EV charging controllers and provides fault signals for DC 6mA and Type-A 30mA + DC 6mA alarms.
Technical Specifications:
  • Rated operating voltage: 230/400VAC
  • Rated current: ≤ 32A
  • Frequency: 50Hz
  • Impulse withstand voltage: 6kV
  • Operating temperature: -40 to 85°C
  • Power consumption: <500mW
  • Electrical endurance: 20,000 cycles
Residual Current Detection:
  • DC residual operating current: 6mA
  • AC residual operating current: 30mA
  • Response times vary based on current type and magnitude, with faster response for higher currents.
Application Notes: The device includes a built-in Mosfet for switching, with a maximum switching current of 500mA. Pin 6 is reserved for internal use and should remain unconnected.
Self-Test and Calibration: A self-test can be initiated by connecting Pin 3 to Vcc for 40ms to 1000ms. Offset calibration requires a connection for 4.5s and should be performed without any current flowing through the sensor.
Output States: The device provides different output states based on the detected current levels, with changes in impedance indicating fault conditions.
Ordering Information: The BRCM01C-12-H1 model is available, featuring a 12V DC interface and compatibility with 1P+N / 3P+N configurations.
