Why Choose the ABB F204 A-40/0.1 Residual Current Circuit Breaker?

The ABB F204 A-40/0.1 is a premium 4 pole residual current circuit breaker (RCCB) designed to provide dependable protection against earth leakage faults in commercial, industrial and infrastructure electrical installations. As part of the trusted ABB F200 Series, it delivers reliable protection for personnel and electrical systems by disconnecting the supply whenever residual fault current is detected.

Featuring a 40 A rated current and a 100 mA rated residual operating current, this RCCB is ideal for three-phase distribution systems requiring dependable earth fault protection. The Type A operating characteristic detects both alternating sinusoidal residual currents and pulsating DC residual currents, making it suitable for installations incorporating electronic equipment, variable speed drives and modern power supplies.

Designed for DIN rail mounting, the ABB F204 A-40/0.1 offers compact dimensions, robust construction and full compatibility with ABB accessories. Its proven reliability and long operational life make it an excellent choice for professional electrical distribution boards and industrial control panels.

Key Advantages

  • Reliable 4 pole RCCB for commercial and industrial installations.
  • 40 A rated current for three-phase electrical distribution.
  • 100 mA residual operating current for dependable earth fault protection.
  • Type A protection against AC and pulsating DC residual currents.
  • Compact DIN rail mounting for professional switchboards.
  • ABB F200 Series quality with excellent long-term reliability.

Key Features

  • ABB F200 Series RCCB.
  • 40 A rated current.
  • 100 mA rated residual operating current.
  • Type A residual current detection.
  • 4 pole configuration.
  • 230 / 400 V AC rated operational voltage.
  • 50 / 60 Hz operation.
  • Instantaneous tripping characteristic.
  • DIN rail mounting.
  • Screw terminal connections.

Reliable Earth Leakage Protection

Residual current circuit breakers continuously monitor the balance between outgoing and returning current. If an earth leakage fault occurs, the RCCB disconnects the circuit almost instantly, helping protect personnel against electric shock while reducing the risk of equipment damage and electrical fires caused by insulation failure.

The ABB F204 A-40/0.1 is ideal for installations incorporating electronic equipment where Type A residual current protection is required. Its dependable performance makes it suitable for commercial buildings, industrial facilities and modern infrastructure projects.
