Why Choose the ABB F204 A-25/0.5 Residual Current Circuit Breaker?

The ABB F204 A-25/0.5 is a dependable four-pole Residual Current Circuit Breaker (RCCB) designed to protect people and electrical installations against earth leakage faults. As part of the trusted ABB F200 series, it provides reliable residual current protection for commercial, industrial and three-phase electrical systems where dependable safety is essential.

Featuring Type A residual current detection, the F204 A-25/0.5 detects both sinusoidal AC and pulsating DC residual currents, making it suitable for modern installations containing electronic equipment, power supplies, automation systems and variable speed drives.

With a 25 A rated current, 500 mA residual operating current and a four-pole configuration, this RCCB is ideal for three-phase distribution boards, industrial machinery and commercial electrical installations requiring reliable earth fault protection.

Key Advantages

  • Reliable ABB F200 series residual current circuit breaker.
  • 25 A rated current for commercial and industrial installations.
  • 500 mA residual current sensitivity for earth leakage protection.
  • Type A protection for AC and pulsating DC residual currents.
  • Four-pole switching suitable for three-phase systems with neutral.
  • Compact DIN rail mounted design for electrical distribution boards.

Key Features

  • ABB F200 RCCB series.
  • Model F204 A-25/0.5.
  • Manufacturer part number 2CSF204101R4250.
  • 25 A rated current.
  • 500 mA residual operating current.
  • Type A residual current protection.
  • 4-pole configuration.
  • Instantaneous tripping characteristic.
  • DIN rail mounting.

Reliable Earth Leakage Protection

Residual Current Circuit Breakers continuously monitor the balance of current flowing through live conductors and neutral. If an earth leakage fault occurs, the RCCB disconnects the circuit rapidly, helping reduce the risk of electric shock, equipment damage and electrical fire.

The ABB F204 A-25/0.5 combines dependable residual current protection with proven ABB engineering, making it suitable for modern electrical installations where long-term reliability and compliance are essential.

Typical Applications

  • Three-phase distribution boards.
  • Industrial control panels.
  • Commercial electrical installations.
  • Manufacturing facilities.
  • Building services.
  • Machinery and automation systems.
