bimetal relay 32...40 A size S2 class 10 DO-3US5600-2R8K

Product Description

Siemens SIRIUS Bimetal Relay – 32…40 A, Size S2, Class 10 – 3US5600-2R8K

The Siemens 3US5600-2R8K is a SIRIUS thermal overload relay (bimetal type) designed for reliable protection of three-phase motors against overload, phase failure, and excessive temperature rise. It ensures safe operation of motors in industrial environments by disconnecting the circuit when current exceeds the set limit for a defined time.

This relay belongs to Size S2 and offers an adjustable current range of 32 to 40 A, making it suitable for medium to heavy-duty motor applications. With a Class 10 tripping characteristic, it provides fast and effective protection for motors under overload conditions, reducing the risk of winding damage and system failure.

It is designed for direct mounting with Siemens SIRIUS contactors, making it ideal for use in motor starters, MCC panels, pumps, compressors, conveyors, and industrial automation systems.
