FAQ Question?What is the significance of the ‘C’ curve in the ‘C4A’ designation?The ‘C’ curve is a tripping characteristic. It means the circuit breaker will trip magnetically between 5 and 10 times the rated current (4A). This makes it suitable for general purpose applications like lighting, sockets, and small motors with moderate inrush currents. Question?Can this iC60N breaker be used in a DC circuit?While the iC60N series is primarily designed for AC circuits as indicated by the 50/60Hz rating, some models have specific DC ratings. However, based on the markings shown, this A9F77204 model is specified for AC use only. Using it on DC circuits without manufacturer confirmation can be unsafe and may not provide adequate protection. Question?What is the difference between the breaking capacity Icn (6000A) and Icu (50kA)?Icn (rated short-circuit capacity) is defined by the IEC/EN 60898-1 standard, typically for residential/commercial installations. Icu (ultimate short-circuit breaking capacity) is from the IEC/EN 60947-2 standard for industrial applications. Icu is generally a more demanding test, and this breaker has a very high Icu rating of 50kA at 240/415V, making it suitable for robust industrial environments where high fault currents can occur. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
