                                    Description
                    
                        Residual current circuit breakers (RCCBs) are designed to protect electrical systems by detecting leakage currents that could lead to electrocution or fire. This component disconnects the circuit when leakage exceeds a preset threshold of 30 mA — ensuring safety in residential, commercial, or industrial installations.
### Specifications 
Four-pole RCCB unit with Type A sensitivity for detecting both sinusoidal AC and pulsed DC leakage currents. Operates under nominal voltage conditions and within specified temperature ranges. Suitable for use in both single-phase and three-phase systems with neutral configuration.
### Operational Characteristics 
Rated residual operating current: 0.03 A provides high protection against earth faults. Conforms to IEC/EN standards for safety compliance — ensures reliable tripping response in standard operational environments. Mechanism tolerates medium-frequency duty cycles; repeated activation is permissible without significant wear on internal components.
#### Technical Notes / Limitations: 
- Rated voltage range: Up to 400 V AC, specific applications require verification of system compatibility. 
- Operating temperature limits between -25°C and +40°C; performance may degrade outside these boundaries.
- Must be installed vertically—horizontal positioning can compromise trip functionality.
- Cannot provide overload or short-circuit protection—requires integration with appropriate MCB or similar device for full coverage.
- Designed exclusively for low-voltage circuits; unsuitable above defined thresholds as per IEC guidelines.
