The Siemens 3RT2326-1AP00 is a high-quality SIRIUS 3RT23 Series power contactor designed for reliable switching of electrical loads in industrial control, power distribution, HVAC, and automation systems. This 4-pole contactor features 4 Normally Open (4NO) main contacts along with 1 NO + 1 NC integrated auxiliary contacts, providing flexible control and monitoring capabilities in a compact design.
Designed for AC-1 applications up to 40A, the 3RT2326-1AP00 is suitable for switching resistive and slightly inductive loads such as heating elements, lighting circuits, power supplies, and industrial control circuits. The contactor operates with a 230V AC, 50/60 Hz coil and ensures dependable performance in demanding industrial environments.
The integrated 1NO + 1NC auxiliary contacts simplify control circuit design by providing built-in signaling, interlocking, and status feedback functions without requiring additional accessories. This reduces panel space requirements and lowers installation costs.
Built in the compact S0 frame size, the 3RT2326-1AP00 offers efficient panel utilization while maintaining excellent switching performance. The robust screw terminal design ensures secure conductor connections, easy maintenance, and long-term operational reliability.
Manufactured according to Siemens SIRIUS quality standards, the contactor provides a rated insulation voltage of 690V, high electrical endurance, and a mechanical life of up to 10 million operating cycles. Its rugged construction makes it ideal for motor control centers (MCCs), industrial machinery, process control systems, building automation, and OEM equipment.
As part of the trusted Siemens SIRIUS 3RT2 contactor family, the 3RT2326-1AP00 delivers reliable switching performance, compact design, and seamless integration with Siemens overload relays, motor starters, and industrial automation products.
