4463AT-48 Thermal Relay Overload Protection Function
The 4463AT-48 thermal relay provides automatic overload protection by interrupting the electrical circuit when temperature exceeds permissible limits due to overcurrent conditions. The device ensures continuous monitoring of thermal operating conditions of electric motors and power units, contributing to operational reliability and system safety.
Operating Principle of Thermal Relay 4463AT-48
The 4463AT-48 thermal relay operates on a bimetallic principle. A temperature-sensitive bimetal element deflects under thermal load and mechanically opens the contacts once the preset threshold is reached. Depending on configuration, the relay may include manual or automatic reset capability and visual trip indication for diagnostics.
Application of 4463AT-48 Thermal Relay in Aviation Systems
The 4463AT-48 thermal relay is used in aircraft and helicopter electrical systems where thermal overload protection is mandatory. Exact trip current parameters and adjustment ranges are defined in the manufacturer’s passport and technical documentation for the specific serial number.
The product is also known under alternative designations 4463АТ-48, which refer to the same product type.
