The ABB DSB202M RCBO from the DS200 series is a high-performance Dual Pole (DP) Residual Current Breaker with Overcurrent protection (RCBO) designed specifically for electrical safety in industrial and commercial electrical installations. This model offers precise protection rated at 63 Amperes, with selectable earth fault sensitivities of 30mA, 100mA, or 300mA, tailored to meet diverse safety requirements. The RCBO effectively safeguards circuits by combining the functions of a residual current device and miniature circuit breaker, providing enhanced protection against overload, short-circuit currents, and earth leakage currents due to sinusoidal alternating earth faults. Additionally, it extends critical safety by preventing hazards arising from both indirect and direct electrical contacts, thereby reducing the risk of electrical shock and fire hazards. Suitable for use in low voltage distribution panels, this compact device ensures compliance with safety standards and is optimized for reliable performance in complex electrical networks. Installation flexibility and robust build quality make the ABB DSB202M an ideal choice for businesses requiring optimal circuit protection and personnel safety.

The selectable earth fault sensitivity allows users to customize the residual current leakage threshold to suit application-specific safety requirements, ranging from highly sensitive 30mA protection for personnel safety to higher thresholds like 100mA or 300mA for system protection and to reduce nuisance tripping.
Yes, the DSB202M is designed as a comprehensive protection device combining an overcurrent circuit breaker and residual current device functions, ensuring simultaneous protection against overload, short-circuits, and earth leakage faults.
The ABB DSB202M RCBO is designed specifically for AC type sinusoidal residual currents and does not provide protection for DC residual currents or pulsating DC earth fault currents.
The double pole design allows disconnection of both line and neutral conductors simultaneously, enhancing electrical safety and compliance in installations where full isolation is required during fault conditions.
This RCBO is DIN rail mountable, facilitating quick and standardized installation in electrical distribution boards.
The RCBOs DS200 series has the function to protect against overload and short-circuit currents; protection against the effects of sinusoidal alternating earth fault currents; protection against indirect contacts and additional protection aganist direct contacts.
