2CSF204199R1100 ABB F204A1000.03110V F204 A-100/0.03 110V RCCB 4P Type A 30mA 100A

Why Choose the ABB F204A1000.03110V Residual Current Circuit Breaker?

The ABB F204A1000.03110V is a high-capacity four-pole Type A residual current circuit breaker (RCCB) designed to provide sensitive earth-leakage protection in electrical distribution systems. As part of the established ABB F200 RCCB series, the F204 A-100/0.03 110V combines a high rated current with 30 mA residual-current sensitivity for applications requiring dependable protection against fault currents to earth.

Rated at 100 A with a 30 mA residual operating current, this Type A RCCB detects sinusoidal alternating residual currents as well as pulsating DC residual currents. This makes it suitable for modern electrical circuits containing electronic equipment that may produce pulsating DC components during an earth fault.

The 110 V version is configured for installations requiring this specific operating-voltage variant. Its four-pole architecture enables simultaneous switching of four conductors, while its modular DIN-rail format allows straightforward integration into distribution boards, switchboards and electrical control panels.

Sensitive Type A Residual-Current Protection

Residual current circuit breakers monitor the current balance between the conductors of an electrical circuit. When an insulation fault or other leakage path causes residual current to flow to earth and the specified operating threshold is reached, the RCCB disconnects the circuit to help protect against electric shock and other hazards associated with earth faults.

The ABB F204 A-100/0.03 110V combines a substantial 100 A current rating with sensitive 30 mA residual-current detection. Its Type A characteristic enables detection of both sinusoidal AC and pulsating DC residual currents, making it appropriate for circuits supplying a broad range of modern electrical equipment.

Typical Applications

• Electrical distribution systems requiring a 110 V RCCB variant.
• Commercial and industrial electrical installations.
• Distribution boards and modular switchboards.
• Electrical control and distribution panels.
• Circuits supplying electronic and electrical equipment.
• Applications requiring 30 mA Type A residual-current protection.
