2CSR252001R1404 ABB DS202 AC-C40/0.03 RCBO 2P Type AC 30mA C40 6kA

Why Choose the ABB DS202 AC-C40/0.03 RCBO?

The ABB DS202 AC-C40/0.03 is a two-pole Type AC residual current circuit breaker with overcurrent protection (RCBO) designed to combine residual-current, overload and short-circuit protection within a single modular device. Part of ABB’s DS200 series 6000, it provides dedicated circuit protection for commercial and industrial electrical distribution systems.

With a rated current of 40 A, a C-curve tripping characteristic and a rated residual operating current of 30 mA, the DS202 AC-C40/0.03 protects against overload and short-circuit currents while responding to sinusoidal alternating earth-fault currents. Its 30 mA sensitivity provides protection against indirect contact and additional protection against direct contact.

The DS202 AC-C40/0.03 operates at 230 V AC and has a rated short-circuit breaking capacity of 6 kA under IEC/EN 61009 requirements. Its two-pole configuration, C-curve overcurrent characteristic and integrated Type AC residual-current protection make it a practical solution for final circuits requiring individual fault isolation and comprehensive electrical protection.

Key Advantages

• Combined RCBO protection against residual current, overload and short circuit within one device.
• 30 mA residual-current sensitivity provides additional protection against electric shock.

Combined Residual-Current and Overcurrent Protection

An RCBO combines the functions of residual-current protection and overcurrent protection within a single protective device. The ABB DS202 AC-C40/0.03 protects its circuit against sinusoidal alternating earth-fault currents as well as overload and short-circuit conditions, enabling dedicated circuit protection without requiring separate RCCB and MCB devices to perform these functions.

Its Type AC characteristic is designed for sinusoidal alternating residual currents, while the C-curve 40 A characteristic is suitable for circuits where moderate starting or inrush currents may occur. Combined with 30 mA residual-current sensitivity and a 6 kA rated short-circuit breaking capacity, the DS202 AC-C40/0.03 provides comprehensive protection for suitable commercial and industrial circuits.

Typical Applications

• Commercial electrical distribution boards.
• Industrial electrical distribution systems.
• Final circuits requiring 40 A C-curve overcurrent protection.
• Circuits requiring 30 mA additional residual-current protection.
• Equipment circuits with moderate normal starting or inrush currents.
• Electrical installations requiring dedicated two-pole RCBO protection and individual fault isolation.
