2CSF202701R1250 ABB F202B+25/0.03 RCCB 2P Type B+ 30mA 25A

Why Choose the ABB F202B+25/0.03 RCCB?

The ABB F202B+25/0.03, order code 2CSF202701R1250, is a high-performance 2-pole Type B+ residual current circuit breaker (RCCB) designed to provide all-current-sensitive residual current protection in demanding electrical installations. As part of the advanced ABB F200 B+ / F200 RCCB range, it is particularly suited to circuits containing power electronics, frequency converters and other equipment capable of producing complex or 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+ characteristic provides comprehensive residual current detection for installations where AC, pulsating DC, smooth DC and higher-frequency residual currents can occur, extending protection for modern power-electronic applications.

The F202B+25/0.03 combines sensitive 30 mA residual current protection with a compact 2-pole DIN rail format. Its all-current-sensitive design makes it suitable for professional electrical distribution systems where conventional Type AC or Type A RCCBs may not provide the required detection of residual currents generated by electronic power conversion equipment.

Advanced Type B+ Residual Current Protection

Residual current circuit breakers monitor current flowing through an electrical circuit and disconnect the supply when residual current to earth exceeds the specified operating threshold. The ABB F202B+25/0.03 combines sensitive 30 mA protection with an all-current-sensitive Type B+ characteristic for electrical systems incorporating sophisticated power electronics.

Type B+ protection is particularly relevant where equipment can generate residual currents with DC components or frequencies beyond those encountered in conventional mains-frequency circuits. This makes the F202B+25/0.03 suitable for appropriately designed installations containing frequency converters, inverter-driven machinery and other electronic power conversion equipment.

Typical Applications

• Commercial and industrial electrical distribution systems.
• Frequency converter and variable-speed drive applications.
• Industrial machinery incorporating electronic power converters.
• Inverter-based electrical equipment.
• Power-electronic systems where smooth DC residual currents may occur.
• Installations requiring all-current-sensitive residual current protection.
• Circuits requiring 30 mA Type B+ residual current protection.
