Residual Current Circuit Breaker with Overcurrent Protection primarily serves to disconnect electrical circuits under fault conditions. It detects residual current—leakage current—and trips to prevent electric shock hazards or fire risks. Incorporates overcurrent protection for load protection during short circuits or overloads. --- **Core Specifications** Rated current: 16A. Adjustable sensitivity threshold responds to leakage currents above predetermined levels (typically 30mA). Voltage range compatibility: Up to 230V AC systems, single-phase configurations only. Breaking capacity indication marked as 10kA conforming to IEC standards. **Construction and Mechanism** Two-pole design with dual functionality for residual-current detection and magnetic thermal cutoff in response to overcurrent events. Includes manual reset mechanism, failsafe tripping if internal faults occur—Permanent On not possible after a trip event until safety verified. --- - Not compatible with DC systems; AC only configuration supported. - Operating temperature limits: -25°C minimum / +40°C maximum. - Mounting compatibility limited to standard DIN rail setups—35mm width profile required. - Leakage sensitivity cannot be adjusted while live; circuit should be disconnected first. - Not rated for use in three-phase networks without intermediate balancing hardware.
