About this item
  • This product is a 63A 30mA Type B RCD Circuit Breaker (Residual Current Circuit Breaker), designed to detect AC (alternating current), pulsating DC, and smooth DC leakage currents,applicable to scenarios requiring broad-spectrum leakage protection, such as electric vehicle charging piles, industrial equipment and solar system.
  • Test report issued by BV (BUREAU VERITAS), complies with LVD Directive 2014/35/EU, meeting IEC/EN 62423 & IEC/EN 61008 safety standards.
  • In the event of an electric shock or leakage accident, the residual current protection device (RCD) circuit breaker will cut off the faulty circuit within 0.1 second, thereby protecting personal safety and preventing fires caused by insulation damage.
  • Compared to Type A RCD, this Type B RCD delivers significantly broader residual current protection - not only maintaining all Type A features, but also providing coverage for various conditions including sinusoidal AC residual currents up to 1000Hz and composite currents where AC is combined with smooth DC components.
  • Rated current 63A, rated voltage 400V AC, When the leakage current in the circuit reaches 30mA (0.03 amps), this product will automatically cut off the power supply within 0.1 seconds, |nc = |△c = 10kA.
  • The compact, space-saving dimensions (72 x 50 x 82 mm) and its Type B leakage protection capability provide long-term protection in demanding electrical environments.
  • Standardised layout of the N-pole terminal on the left side, with a ‘left neutral, right live’ structure design that conforms to electrical engineering practices, effectively reducing the risk of wiring errors and making installation safer and more convenient.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
