ABB 2CSR256040R3255 DS203NC Residual Current Circuit Breaker

Description

• The ABB 2CSR256040R3255 DS203NC is an advanced 3P+N (Three-Phase and Neutral) Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed to provide comprehensive electrical protection across a range of scenarios. With four modules, this device is engineered to safeguard electrical circuits and installations against multiple hazards, including short-circuit currents, overloads, earth fault currents, indirect contacts, and additional protection against direct contacts with versions available at 30 mA sensitivity.

• One of the primary functions of this RCBO is to offer robust protection against short-circuit currents. These abrupt electrical events can cause significant damage to circuits and equipment and pose substantial safety risks. The RCBO swiftly identifies short-circuit conditions and acts promptly to interrupt the circuit, preventing damage and mitigating potential harm to individuals.

• Additionally, the device is equipped to manage overload situations effectively. Overloads can occur due to various factors, such as heightened electrical demand or equipment malfunctions. The RCBO continuously monitors current flow within the circuit and responds by disconnecting the supply if it detects a prolonged overload condition. This feature is essential for preserving the longevity and safety of electrical installations.
