2CSR246140R3164 ABB - DS203NC L C16 A300

The DS203NC L C16 A300 is a three-pole Residual Current Circuit Breaker with Overcurrent Protection (RCBO) from ABB, designed to provide comprehensive protection against both overload/short-circuit and earth fault currents. This device combines the functionality of a Miniature Circuit Breaker (MCB) and a Residual Current Device (RCD) in a single compact unit. It has a C16 tripping characteristic, indicating it is suitable for protecting circuits with moderate inrush currents, commonly found in residential and commercial applications. The A300 denotes a 300mA residual current sensitivity, offering a balance between protection against earth leakage faults and minimizing nuisance tripping. This RCBO is designed for DIN rail mounting, ensuring easy installation in standard distribution boards and consumer units. It provides reliable protection to prevent electrical shocks and fire hazards caused by insulation faults. The DS203NC series is known for its robust construction and compliance with international standards, ensuring safety and performance. It is suitable for a wide range of applications, including lighting, power outlets, and other electrical equipment. This device enhances electrical safety by quickly disconnecting the circuit in the event of a fault, minimizing the risk of damage and injury.
