Siemens Industrial Controls 3UB85335HW2 50/200A 3Ph Overload Relay
The Siemens Industrial Controls 3UB85335HW2 is a three-phase, 50/200 amp overload relay designed to protect electrical motors and other equipment in industrial control systems and high-demand HVAC applications. This important gadget serves as a safeguard against possible harm brought on by an excessive current draw. Consider a fuse as a circuit overload protector. In a similar manner, the overload relay monitors and stops the flow of electricity to a motor or other piece of equipment. It keeps an eye on the current passing through the power supply's three phases constantly. This model has an adjustable current limit of 50 to 200 amps. The overload relay trips a device that shuts off the power to the protected equipment if the current exceeds this limit.
