product details

RCBOs type B grant protection to persons and machineries in presence of DC current and high frequency AC fault current. Among the several types of RCBOs, type B provides the utmost level of protection.

1. Residual current sensitivity – UNIVERSAL
  • AC pure sinus residual current, 50/60Hz

  • A sinus and pulsating direct current, 50/60Hz

  • B: AC + A + smooth direct current + high frequency (1kHz)

2. Standards
  • IEC/EN 61009-1 Basic standards for RCBOs AC and A type

  • IEC/EN 62423 additional requirements for type B

3. Typical applications
  • Fault protection (protection against indirect contact of live parts

  • Additional protection (protection in case of direct contact of live parts, I∆n≤30mA)

  • Fire Protection (for locations exposed to fire hazard, I∆n≤300mA)

4.Which are vulnerable to smooth DC residual currents?
  • Photovoltaic systems, AC side.

  • Charging stations for electric vehicles.

  • Variable speed machine tools.

  • UPS, computer data centers.

  • Elevator controls.

  • Cranes of all kinds.

  • Electronic equipment on construction sites.

  • Test set-ups in laboratories.

  • General installations where DC smooth direct residual currents can be expected.

GFL2-40B  B type RCBO maximum current can reach 40 amps, and three leakage current options of 30mA, 100mA and 300mA are available to meet the needs of different scenarios.

B class
Tripping is ensured for sinusoidal AC residual currents pulsed DC residual currents, alternating residual sinusoidal currents up to 1000Hz, pulsating direct residual currents and for smooth direct residual currents, whether applied suddenly or increasing slowly.

They react to AC and pulsating DC fault currents which reach 0 or almost 0 within one time period of the main frequency.
