RPSG

RPSG stands for Residual Current Protection Switch with Ground-fault protection, commonly known in the industry as RCCBs (Residual Current Circuit Breakers) or RCDs (Residual Current Devices). These devices are designed to detect leakage currents to earth and automatically disconnect the circuit to prevent electric shock or fire hazards. They are available in various configurations, including 2-pole (2P) and 4-pole (4P) versions, with rated currents typically ranging from 25A to 125A and rated residual operating currents (IΔn) of 30mA, 100mA, 300mA, or 500mA. The RPSG series offers Type AC, Type A, and Type B sensitivity, ensuring compatibility with different load types, from sinusoidal AC currents to pulsating DC and smooth DC components. They are designed for modular DIN rail mounting, making them suitable for installation in standard distribution boards. Key technical parameters include rated voltage up to 240V AC (2P) or 415V AC (4P), short-circuit withstand capacity (Icn) up to 10kA, and mechanical endurance exceeding 10,000 operations. These devices comply with international standards such as IEC 61008 and IEC 61009, ensuring reliability and safety in industrial and commercial applications.

RPSG devices are primarily used in electrical distribution systems for protection against indirect contact and fire risks. They are installed in main distribution boards (MDBs), sub-distribution boards (SDBs), and final distribution circuits in residential, commercial, and industrial buildings. Common applications include protection of socket-outlet circuits, lighting circuits, and power circuits in environments with high moisture or conductive materials, such as kitchens, bathrooms, swimming pools, and construction sites. In industrial settings, they safeguard machinery and equipment in wet or dusty areas, such as food processing plants, chemical factories, and water treatment facilities. They are also essential in renewable energy systems, like photovoltaic installations, where they protect against leakage currents from inverters. Additionally, RPSG devices are used in temporary power distribution for events, construction sites, and emergency services, ensuring compliance with local electrical safety regulations.

The RPSG category includes several subcategories and key article codes. The main subcategories are: RPSG-2P (2-pole residual current circuit breakers) and RPSG-4P (4-pole residual current circuit breakers). Key article codes include RPSG-2P-25A-30mA, RPSG-2P-40A-30mA, RPSG-2P-63A-30mA, RPSG-2P-80A-100mA, RPSG-2P-100A-300mA, RPSG-4P-25A-30mA, RPSG-4P-40A-30mA, RPSG-4P-63A-30mA, RPSG-4P-80A-100mA, and RPSG-4P-125A-500mA. The article code structure typically follows the pattern: RPSG-[Number of Poles]-[Rated Current]-[Residual Current], where the number of poles is either 2P or 4P, rated current is in amperes (e.g., 25A, 40A, 63A), and residual current is in milliamperes (e.g., 30mA, 100mA, 300mA). For example, RPSG-2P-63A-30mA indicates a 2-pole device with a 63A rated current and 30mA residual sensitivity. These codes are standardized across the series for easy identification and ordering.
