2CSF202568R1250 ABB F202 B-25/0.03 RCCB 2P Type B 30mA 25A

Why Choose the ABB F202 B-25/0.03 RCCB?

The ABB F202 B-25/0.03, order code 2CSF202568R1250, is a high-performance 2-pole Type B residual current circuit breaker (RCCB) designed to protect people and electrical installations against a broad range of residual currents to earth. As part of the established ABB F200 / FH200 RCCB product group, it is particularly suited to modern electrical systems containing power electronics, converters and equipment capable of generating smooth DC residual currents.

This RCCB has a rated current of 25 A and a rated residual operating current of 30 mA. Its Type B residual current characteristic extends protection beyond conventional Type A devices by detecting sinusoidal AC, pulsating DC and smooth DC residual currents, making it suitable for applications where electronic power conversion equipment can create complex fault-current waveforms.

The F202 B-25/0.03 features a compact 2-pole DIN rail format for integration into modular electrical distribution boards. Its 30 mA sensitivity provides additional protection against electric shock in suitable installations, while Type B detection makes it an appropriate choice for circuits where DC residual currents could otherwise affect the operation of conventional residual current protection devices.

Comprehensive Type B Residual Current Protection

Residual current circuit breakers monitor current flowing through an electrical circuit and disconnect the supply when a residual current to earth exceeds the specified operating threshold. The ABB F202 B-25/0.03 provides sensitive 30 mA protection while its Type B characteristic enables detection of residual current waveforms associated with modern power electronic equipment.

Unlike residual current devices intended primarily for AC and pulsating DC faults, Type B RCCBs can also detect smooth DC residual currents. This makes the F202 B-25/0.03 suitable for appropriately designed circuits containing equipment such as converters, variable-speed systems and other electronic loads capable of producing DC components under fault conditions.

Typical Applications

• Commercial and industrial electrical distribution systems.
• Circuits containing power electronic converters.
• Variable-speed drive and inverter applications.
• Industrial machinery incorporating electronic power conversion.
• Renewable energy and power conversion equipment where Type B protection is specified.
• Electrical systems where smooth DC residual currents may occur.
• Circuits requiring 30 mA Type B residual current protection.
