2CSF202101R4900 ABB F202 A-100/0.5 RCCB 2P Type A 500 mA 100 A

Why Choose the ABB F202 A-100/0.5 RCCB?

The ABB F202 A-100/0.5 is a 2-pole Type A residual current circuit breaker (RCCB) from the ABB F200 series, designed to provide residual-current protection for people and electrical installations against fault currents to earth. Supplied under ABB order code 2CSF202101R4900, it combines a high rated current of 100 A with a rated residual operating current of 500 mA.

As a Type A RCCB, the F202 A-100/0.5 is designed to respond to both sinusoidal alternating residual currents and pulsating direct residual currents. This makes it suitable for compatible residential, commercial and industrial electrical installations containing modern electrical and electronic loads capable of producing these residual-current waveforms.

The F202 A-100/0.5 provides instantaneous operation at a rated voltage of 230 V and frequency of 50/60 Hz. Its two-pole modular construction measures 85 × 35 × 69 mm and is designed for DIN-rail installation, providing high-current residual-current protection in a compact format.

Key Advantages

• 100 A rated current for higher-current compatible low-voltage circuits.
• 500 mA rated residual current for appropriate earth-fault and leakage-current protection applications.
• Type A detection for sinusoidal AC and pulsating DC residual currents.
• 2-pole configuration for compatible single-phase installations.
• Instantaneous operating characteristic without intentional time delay.
• 10 kA rated conditional short-circuit current when correctly coordinated with suitable backup protection.
• Part of ABB's established F200 RCCB series for residential, commercial and industrial applications.

Type A Residual-Current Protection for Higher-Current Circuits

Type A RCCBs are designed to detect both sinusoidal alternating residual currents and pulsating direct residual currents. This broader residual-current response makes the ABB F202 A-100/0.5 suitable for compatible circuits containing electrical and electronic equipment capable of producing pulsating DC components during fault conditions.

With its 100 A current rating and 500 mA residual-current sensitivity, the F202 A-100/0.5 is suited to appropriate higher-current earth-fault and installation-protection applications. It is an RCCB rather than an RCBO and therefore does not provide integral overload or short-circuit protection; suitable overcurrent protection must be provided separately according to the circuit design, applicable standards and ABB coordination requirements.

Typical Applications

• Residential electrical distribution systems.
• Commercial electrical installations.
• Industrial low-voltage distribution systems.
• Compatible higher-current single-phase circuits.
• Circuits with loads capable of producing pulsating DC residual currents.
• Earth-fault and leakage-current protection applications.
• DIN-rail distribution and control panels.
