Why Choose the ABB F204 A S-40/0.5 Residual Current Circuit Breaker?

The ABB F204 A S-40/0.5 is a premium four-pole selective residual current circuit breaker (RCCB) designed to provide dependable earth fault protection in commercial, industrial and infrastructure electrical installations. As part of the trusted ABB F200 RCCB series, it protects people and equipment by detecting residual current faults while offering selective time-delayed operation for improved discrimination with downstream protective devices.

This Type A selective RCCB detects alternating residual currents and pulsating DC residual currents generated by modern electrical equipment. Its 40 A rated current and 500 mA residual operating current make it ideal for upstream protection where coordinated tripping helps maximise system availability.

Featuring a compact four-pole DIN rail mounted design, the F204 A S-40/0.5 is engineered for three-phase electrical distribution systems requiring dependable protection, robust construction and selective operation. It is suitable for demanding industrial environments, switchboards and control panels.

Key Advantages

  • Selective four-pole RCCB for three-phase electrical installations.
  • 40 A rated current for commercial and industrial distribution systems.
  • 500 mA residual current sensitivity for installation-level earth fault protection.
  • Type A residual current detection for AC and pulsating DC residual currents.
  • Selective time-delayed tripping improves coordination with downstream RCCBs.
  • Compact DIN rail mounting for switchboards and control panels.

Key Features

  • ABB F200 residual current circuit breaker series.
  • Four-pole (4P) RCCB configuration.
  • 40 A rated operational current.
  • 500 mA rated residual operating current.
  • Type A selective residual current protection.
  • Suitable for 230 / 400 V AC electrical systems.
  • 5 kA maximum surge current.
  • DIN rail mounting with screw terminal connections.

Selective Earth Fault Protection for Reliable Distribution

Residual current circuit breakers continuously monitor the balance between live conductors and the neutral conductor. If earth leakage is detected, the RCCB disconnects the circuit to help reduce the risk of electric shock, electrical fires and damage to connected equipment.

The selective operating characteristic of the ABB F204 A S-40/0.5 provides delayed tripping compared with downstream RCCBs, improving discrimination and helping maintain continuity of service by isolating only the affected section of an installation.

Typical Applications

  • Commercial electrical distribution boards.
  • Industrial switchboards and control panels.
  • Three-phase power distribution systems.
  • Building services and infrastructure installations.
  • Machinery and automation systems.
  • Upstream selective residual current protection.

Frequently Asked Questions

What is the ABB F204 A S-40/0.5 used for?

The ABB F204 A S-40/0.5 provides selective residual current protection for three-phase electrical installations, helping isolate earth leakage faults while coordinating with downstream RCCBs.

What does the 500 mA rating mean?

The 500 mA residual operating current is the earth leakage level at which the RCCB is designed to disconnect the circuit.

What does Type A protection mean?

Type A RCCBs detect alternating residual currents and pulsating DC residual currents generated by modern electronic equipment.

What is the benefit of a selective RCCB?

A selective RCCB provides intentional time-delayed operation to improve discrimination with downstream residual current devices, helping reduce unnecessary upstream power interruptions.

How is the ABB F204 A S-40/0.5 installed?

The RCCB mounts directly onto a standard DIN rail within distribution boards, switchboards and electrical control panels.
