Thermal overload relay is a device to protect an electrical device like a motor/generator from catching fire or burning out due to excessive heat produced during operation. When excessive current flows through the motor circuit, the relay opens due to increased motor temperature, relay temperature, or sensed overload current.
- Protection against overload and Single phasing
- Mainly for close protection of motors
- Potential trip free contacts
- Used with various type of contactors
