3TH4373-0BF4
The 3TH4373-0BF4 is a Siemens SIRIUS 3TH4 auxiliary contactor with a contact combination of 7 normally open + 3 normally closed for a total of 10 poles. It is driven by a DC 110V coil and has contact ratings of AC-15 230V/10A and 400V/6A. It uses screw terminal wiring and is suitable for signal expansion and interlocking applications in DC control circuits.
Product Positioning
The 3TH4373-0BF4 belongs to the SIRIUS 3TH4373 sub-series. It is a 10-pole auxiliary contactor with 7 normally open and 3 normally closed poles, driven by a DC 110V coil, and is suitable for panel designs using 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 fixed contacts consist of 7 normally open and 3 normally closed contacts, which take into account both signal output and interlock feedback.
DC110V DC coil
The coil is a DC 110V DC operating type, suitable for DC control circuits or battery backup power systems.
AC-15 contact rated
The contacts are rated AC-15 230V/10A, and 6A at 400V, which can withstand the switching of general electromagnetic loads.
Dual-bridge forced guidance contact
The contacts adopt a double-bridge contact structure and have positive drive characteristics, which improves the contact reliability under low energy signals.
Compliant with international safety regulations
It complies with EN 50011 and IEC 60947-5-1 standards and has NEMA A600 control contact rating.
