Product Positioning

The 3TH4293-0BB4 is a rare hybrid contactor relay in the Siemens SIRIUS series, featuring 4 normally open and 4 normally closed contacts. It is suitable for control circuit designs that require simultaneous acquisition of normally open and normally closed signals.

Core Product Advantages and Features
4NO+4NC hybrid contact
The 8-pole contact configuration includes 4 normally open and 4 normally closed contacts, which can simultaneously output both open and close control signals, reducing the need for additional intermediate relays.
24V DC coil design
The coil has a rated control voltage of 24V DC, is suitable for low-voltage DC control circuits, and is commonly used in PLC output stage linkage applications.
Screw terminal and guide rail installation
Both the main and auxiliary circuits use screw terminals and support a dual fixing method of 35mm guide rail clips and screws, making installation more flexible.
Stable operation over a wide temperature range
It can operate in ambient temperatures ranging from -25°C to +55°C, making it suitable for most indoor industrial distribution boxes and control panels.
