Product Positioning

The Siemens SIRIUS 3TH4346-0BB4 is a 10-pole control relay (auxiliary contactor) that provides 10 sets of auxiliary contacts, including 7 normally open and 3 normally closed contacts. It is driven by a 24V DC coil and is suitable as a signal extension or control circuit switching element for the main contactor.

Core Product Advantages and Features
24V DC coil drive
It uses a 24V DC coil power supply and is suitable for direct drive applications of DC control circuits and PLC output signals.
7 normally open and 3 normally closed contact configuration
Ten sets of fixed auxiliary contacts (7NO+3NC) allow for simultaneous switching of multiple control circuits, enhancing wiring flexibility.
Conforms to international standards
The design conforms to IEC 60947-5-1 and EN 50011 standards and is compatible with Siemens SIRIUS series components.
DIN rail quick installation
Supports 35mm standard DIN rail snap-fit installation and screw terminal wiring, facilitating panel configuration and maintenance.
