2CSR252001R1104 ABB DS202 AC-C10/0.03 RCBO 2 Pole 10 A 30 mA 6 kA

Why Choose the ABB DS202 AC-C10/0.03 RCBO?

The ABB DS202 AC-C10/0.03 is a compact and dependable two-pole residual current circuit breaker with overcurrent protection (RCBO) designed to protect electrical circuits against overloads, short circuits and AC residual currents. As part of the ABB DS200 RCBO series, it combines miniature circuit breaker and residual-current protection functions in a single DIN-rail device.

This RCBO provides Type AC residual-current protection together with a Type C tripping characteristic, making it suitable for circuits with moderate inrush currents. By combining overcurrent and earth-leakage protection in one device, the DS202 helps simplify distribution-board design while providing individual circuit protection.

With a rated current of 10 A, a rated residual operating current of 30 mA and a rated short-circuit capacity of 6 kA, the DS202 AC-C10/0.03 is suitable for final circuits in residential, commercial and similar electrical installations. Its two-pole configuration provides simultaneous switching and protection of both conductors.

Key Advantages

• Combined overload, short-circuit and residual-current protection in one device.
• 10 A rated current for lower-current final circuits.
• 30 mA residual-current sensitivity for additional protection against electric shock.
• Type AC residual-current characteristic for sinusoidal AC residual currents.
• Type C tripping characteristic suitable for circuits with moderate starting currents.
• 6 kA short-circuit breaking capacity for dependable fault protection.

Key Features

• ABB DS200 RCBO series.
• 10 A rated current.
• 30 mA rated residual operating current.
• C-curve overcurrent characteristic.
• Type AC residual-current characteristic.
• Two-pole configuration.
• 6 kA rated short-circuit capacity.
• Combined residual-current and overcurrent protection in a compact DIN-rail format.

Combined Residual-Current and Overcurrent Protection

An RCBO combines the functions of a miniature circuit breaker and a residual current device. It disconnects the protected circuit when an overload or short circuit occurs and also responds when residual current to earth exceeds the specified operating threshold, allowing comprehensive protection to be provided by a single modular device.

The ABB DS202 AC-C10/0.03 uses a C-curve overcurrent characteristic and Type AC residual-current detection. Its 30 mA sensitivity makes it suitable for final circuits requiring additional residual-current protection, while individual RCBO protection can help limit a fault to the affected circuit rather than disconnecting multiple circuits together.

Typical Applications

• Residential electrical distribution boards.
• Commercial and light industrial installations.
• Lighting and general final circuits.
• Socket and equipment circuits within the device rating.
• Circuits requiring combined overcurrent and residual-current protection.
• DIN-rail distribution systems requiring individual circuit protection.
