The Siemens Solid-State Overload Relay is a reliable and high-performance electrical component designed for protecting motors and other electrical devices from overload and thermistor-related issues. With its integrated thermistor protection, it provides accurate and efficient temperature monitoring to prevent overheating and potential damage to machinery.

This overload relay has a current range of 125 to 500 A, allowing it to handle a wide range of load capacities. It is compatible with AC voltage of 110 to 120V and operates at a frequency of 50/60Hz, making it suitable for various electrical systems.

One of the key features of this overload relay is its internal earth-fault detection capability. It can detect and respond to earth faults, providing additional protection against electrical hazards. The contact configuration includes 1 normally open (NO) and 1 normally closed (NC) contact for overload/thermistor, as well as 1 NO and 1 NC contact for earth fault.

The bistable outputs of this Siemens Solid-State Overload Relay ensure reliable and stable electrical connections, contributing to the overall efficiency and performance of the electrical system.
