Product Positioning

The SIEMENS SIRIUS 3TH4394-0BB4 is a 10-pole contactor relay from the 3TH4 series. In addition to the standard 4NO+4NC contacts, it is equipped with one set of early-make NO contacts and one set of late-break NC delay contacts. The coil voltage is DC 24V, and it is suitable for control circuits that require sequential operation.

Core Product Advantages and Features
10-pole contact with motion delay design
In addition to the standard 4NO+4NC contacts, an extra set of early-closing NO contacts and a set of late-opening NC contacts are provided to meet the interlocking timing control requirements.
DC 24V coil
The coil is rated for 24V DC and is suitable for industrial control panel applications using general DC control power supplies.
Screw terminals and guide rail mounting
It uses screw terminals for wiring and can be screwed or clipped onto a 35mm standard guide rail, providing excellent installation flexibility.
Compliant with international control relay standards
The design complies with relevant standards of EN 50011 and IEC 60947-5-1 to ensure the reliability of contact operation.
