Thermal Overload Relay, 3UA Series, Variant EZ2 - 3UA58002EZ2

🔹 Siemens Thermal Overload Relay – 3UA58002EZ2 (3UA Series, Variant EZ2)

🔹 Product Description

The Siemens 3UA58002EZ2 is a thermal overload relay from the Siemens 3UA Series, designed to deliver reliable motor protection in industrial motor control systems. It protects electric motors from overload, phase loss, and overheating, ensuring safe and efficient operation in demanding environments.

This EZ2 variant belongs to the 3UA5800 frame range, typically used for medium to higher current motor applications. It is commonly installed with Siemens contactors (such as 3TF series) in motor starter assemblies used for pumps, compressors, conveyors, and heavy industrial machinery.

The relay works on a bimetal thermal principle, where excess current heats the bimetal strips, causing precise tripping action that disconnects the motor circuit and prevents equipment damage.
