The ABB KT7XU4 is a high-performance undervoltage release designed to ensure the safety and reliability of electrical systems. This device operates at a voltage range of 220-240VAC and is engineered to trip at 35-70% of the undervoltage voltage rating, making it ideal for a variety of industrial applications. The KT7XU4 model, part of the T7-X1 series, is specifically crafted to provide precise protection by preventing the re-energization of the circuit until the voltage returns to a safe level. With a net weight of 13.44 oz and a similar gross weight, this compact yet robust unit is essential for maintaining system integrity and preventing equipment damage due to voltage drops.
