ABB 2CSR253001R1164 DS203 AC-C16/0.03 RCBO

Overview of ABB 2CSR253001R1164

The ABB 2CSR253001R1164, also known as DS203 AC-C16/0.03, is a residual current breaker with overcurrent protection (RCBO) designed for low-voltage electrical distribution systems. It belongs to the ABB DS200 series, which integrates residual current protection and circuit breaker functionality into a single compact device.

This device is widely used in industrial, commercial, and infrastructure electrical systems where both personnel safety and equipment protection are required. It provides protection against overload currents, short-circuit faults, and earth leakage currents.

By combining multiple protection functions in one unit, the device improves installation efficiency and reduces panel space requirements.

Functional Principle of RCBO Protection

The ABB DS203 RCBO operates by continuously monitoring electrical current flowing through a circuit. It detects abnormal conditions such as overload, short circuits, and leakage currents to earth.

When a fault condition is detected, the device automatically disconnects the circuit to prevent damage to equipment and reduce the risk of electrical hazards. This ensures both system protection and personnel safety.

The residual current protection function is designed to detect imbalance between phase and neutral currents, which indicates leakage to ground.

Integration of MCB and RCD Functions

One of the key features of ABB 2CSR253001R1164 is the integration of miniature circuit breaker (MCB) and residual current device (RCD) functions into a single RCBO unit.

This integration allows the device to provide both overcurrent protection and earth leakage protection simultaneously, reducing the need for multiple separate devices in electrical panels.

This design improves system reliability and simplifies installation in industrial and commercial electrical systems.

Industrial Application Areas

The ABB DS203 RCBO is used in a wide range of applications including industrial control panels, commercial buildings, machinery power distribution, and infrastructure electrical systems.
