Eaton C440A1A045SDD Electronic Overload Relay

The Eaton C440A1A045SDD Electronic Overload Relay is a motor protector that guards electrical motors by monitoring current and providing overcurrent protection for motor circuits within a 9 to 45 ampere range. Identified by the exact part number C440A1A045SDD, this electronic overload relay is part of Eaton's motor protection lineup and is designed to protect motors operating within that current window from overload conditions. With a 9–45 A protection range, it offers an electronic alternative to traditional thermal overload devices for applications requiring current-based sensing. The Eaton branding and model code help users confirm the correct part for procurement and integration into motor protection schemes that rely on electronic protective relays. Using this relay helps prevent motor overheating and potential damage caused by overload, contributing to reduced downtime and longer motor life when the running current stays within the specified range.
