Description
Siemens Industrial Controls 3RU2136-4GB0 Thermal Overload-Relay is used to protect motors in HVAC systems by monitoring for overload conditions and protecting the motor. Temperature changes in the motor windings are sensed, with a trip class 10, meaning that it will trip 10 times the rated current. This has a current range of 36-45A and size of S2, which makes it perfect for HVAC applications where motor protection is essential. Motor overload protection assists extend motor life, enhance reliability, and clear the need to replace high current limiting motors when actually the overload is not necessary.
