ABB F 372 25/0.03A

ABB F 372 Residual Current Circuit Breaker Description The ABB F 372 is a high-quality Residual Current Circuit Breaker (RCCB) designed to provide essential safety in electrical installations. It offers reliable protection against earth leakage currents, thus preventing electric shock and minimizing fire risks. This 2-pole device is rated for 25A and has a tripping sensitivity of 30mA, making it suitable for a wide range of residential and commercial applications. Its robust construction ensures long-term performance and reliability, typical of ABB products. Specifications Manufacturer: ABB Model: F 372 Type: Residual Current Circuit Breaker (RCCB) Number of Poles: 2 Rated Current (In): 25 A Rated Residual Current (IΔn): 30 mA (0.03 A) Rated Voltage (Un): 230V AC Rated Breaking Capacity: 3000 A Mounting: DIN Rail Label Info F 372 25A IΔn 0.03A U 230V~ 3000 2 pol. Certification: CEBEC Application This RCCB is ideal for installation in distribution boards for the protection of final circuits in domestic, commercial, and light industrial environments. It is a critical component for circuits supplying socket outlets and equipment where there is a risk of direct contact. Country of Origin This product is manufactured by ABB in Germany. CO2 Impact Opting for a refurbished component like this ABB F 372 avoids the production of a new one, saving an estimated 8.8 kg of CO2. This saving is comparable to the emissions of driving a car for 44 kilometers. Availability This item is in stock and ready for immediate dispatch.

FAQ What is the difference between an RCCB like the F 372 and an MCB?An RCCB (Residual Current Circuit Breaker) is designed to protect against electric shock from earth faults by detecting small leakage currents. An MCB (Miniature Circuit Breaker) protects equipment against overcurrents (overload and short-circuits). They serve different but complementary safety functions. Is this RCCB suitable for protecting circuits with modern electronic devices?The F 372 is a Type AC RCCB, which is designed to detect sinusoidal AC fault currents. For circuits with modern electronics that can produce pulsating DC fault currents, a Type A or Type B RCCB is generally recommended for enhanced safety. How do I correctly test the functionality of this F 372 RCCB?The functionality should be checked regularly, typically every month, by pressing the ‘T’ or ‘TEST’ button on the front of the device. When pressed, the RCCB should trip immediately, cutting off the power. If it does not trip, it must be replaced by a qualified electrician. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
