The Hager ESC464 4P is a four-pole power relay designed for electrical distribution and control applications in residential, commercial, and industrial sectors. This relay allows for the reliable switching of electrical circuits through its four-pole configuration, enabling the simultaneous control of multiple circuits or phases. Made from durable materials, the ESC464 features a compact design that facilitates easy installation in standard enclosures and distribution boxes. The relay operates with a nominal voltage that is typically compatible with European standard systems, with specific voltage values needing to be adjusted to local requirements. Measuring approximately 90 mm in height, 70 mm in width, and 60 mm in depth, and weighing around 450 g, this relay offers a space-saving solution for electrical control needs. The ESC464 is designed for long-term reliability under various environmental conditions, with operating temperatures ranging from -25 °C to +55 °C. The screw terminal connections ensure secure wiring, while the transparent cover allows for visual monitoring of the relay status. This model is the successor to previous Hager power relay designs and incorporates improvements in switching capacity and mechanical durability. Suitable for applications such as lighting control, HVAC systems, motor control, and automated processes, the Hager ESC464 4P power relay represents a practical component for electrical professionals seeking reliable circuit management solutions in building automation and industrial installations.
