The Siemens 3RT2326-1AP00 is a genuine Siemens SIRIUS 3RT23 four-pole contactor designed for reliable switching of electrical loads in industrial control and automation applications. It is rated for 40 A in AC-1 utilization category at 400 V and 40°C, making it suitable for switching non-inductive or low-inductive loads in industrial electrical systems. Siemens identifies this model as part of the SIRIUS 3RT.3 four-pole contactor family.
The contactor features a 230 V AC control supply at 50 Hz and includes 1 NO + 1 NC auxiliary contacts for control, signaling, interlocking and automation functions. Both the main and auxiliary circuits use screw terminals, providing secure and practical electrical connections in control-panel installations. The compact Size S0 design is suitable for industrial control cabinets where dependable switching performance and efficient panel-space utilization are required.
The 3RT2326-1AP00 provides a 4-pole switching configuration with 4 normally open main contacts. Its integrated 1 NO + 1 NC auxiliary contacts can be used for feedback, electrical interlocking, status signaling and control-circuit applications.
With its 40 A AC-1 rating, 230 V AC coil and four-pole construction, this Siemens contactor is suitable for applications such as resistive loads, heating systems, HVAC equipment, lighting control, power distribution and industrial automation panels.
The contactor has a 690 V rated insulation voltage and 6 kV surge withstand capability for both the main and auxiliary circuits. The front and terminals have IP20 protection.
