This ABB RCBO (Residual Current Circuit Breaker with Overcurrent Protection) from the DSE201 series is designed for electricians and system integrators needing reliable overcurrent and earth fault protection in electrical installations. Its key benefit is combining two protective functions (overcurrent and residual current) into a single device, saving space and simplifying wiring. A potential caveat is its specific trip sensitivity (30mA) and breaking capacity (6kA), which must match the installation's requirements.

An MCB (Miniature Circuit Breaker) protects against overcurrents (overloads and short circuits). An RCD (Residual Current Device) protects against earth leakage currents. An RCBO combines both functions, providing overcurrent and earth leakage protection in a single device.
'C32' refers to the Type C tripping characteristic and a 32A current rating. 'A30' signifies a 30mA residual current tripping sensitivity. The 'A' often indicates a standard AC-sensitive type.
No, this is a 2-pole RCBO designed for single-phase circuits. For 3-phase applications, you would typically use 4-pole RCBOs or a combination of 3-pole MCBs and a 4-pole RCD.
It is recommended to test the residual current function using the test button at least once a year, or more frequently if required by local regulations or the installation environment.
The breaking capacity (Icn) at its rated voltage (264V AC) is 6 kA.
This device is designed for installation within an electrical enclosure. It should not be exposed directly to outdoor elements unless the enclosure itself provides adequate protection (e.g., IP rating).
Warranty information is typically provided by the distributor or retailer. Please refer to your purchase documentation or contact the seller for specific warranty details.
This indicates a persistent fault in the circuit or connected appliance. Check for short circuits or high leakage currents. Test individual appliance circuits if possible or consult a qualified electrician.
The residual current detection function may be faulty. Do not rely on this device for earth fault protection. Replace the RCBO immediately and have the installation checked by a qualified electrician.
The circuit may be overloaded, or there might be a low-level earth leakage current. Check the total load on the circuit and ensure it does not exceed the 32A rating. Inspect wiring for any signs of damage or insulation degradation.
This can happen if a surge causes a temporary earth leakage or overvoltage condition. While the RCBO might protect the circuit, consider installing a surge protection device (SPD) for added protection against transient events.
