3TH4373-0BB4
The 3TH4373-0BB4 is a Siemens SIRIUS 3TH4 auxiliary contactor with a 10-pole contact combination of 7 normally open + 3 normally closed contacts. It is driven by a DC 24V coil, with contact ratings of AC-15 230V/10A. It features a screw terminal design and is suitable for signal expansion in PLC or DC 24V control systems.
Product Positioning
The 3TH4373-0BB4 is a 10-pole auxiliary contactor in the SIRIUS 3TH4373 sub-series, with a combination of 7 normally open and 3 normally closed contacts. It is equipped with a DC24V coil commonly used in the industry and is suitable for integration with PLCs or DC control power supplies.
Core Product Advantages and Features
7 normally open and 3 normally closed contact configuration
The identification code is 73E, and the 10 sets of fixed contacts provide a combination of 7 normally open and 3 normally closed contacts to meet the needs of multi-loop control and feedback.
DC24V coil
The coil voltage is the industry-standard DC24V, making it easy to use directly with PLC outputs or DC power supply modules.
AC-15 contact rated
The contacts are rated AC-15 230V/10A and can be used for switching general electromagnetic contactors or indicating circuits.
Dual-bridge forced guidance contact
It adopts a dual-bridge contact and forward drive structure, which still maintains high contact reliability under low energy signal conditions.
Compliant with international safety regulations
It conforms to EN 50011 and IEC 60947-5-1 standards and has NEMA A600 contact rating.
