3RT20261DB443MA0
3-pole S0 housing power contactor, AC-3 rated 25A, 11kW/400V, AC-1 up to 40A, 24V DC coil with 2NO+2NC four sets of auxiliary contacts.
Product Positioning
The 3RT2026-1DB44-3MA0 is a Siemens SIRIUS 3RT2026 series S0 housing contactor. The main circuit AC-3 is rated at 25A, corresponding to 11kW at 400V, while AC-1 can reach 40A. The operating coil is 24V DC and has four built-in auxiliary contacts (2NO + 2NC). It is suitable for motor control circuits requiring numerous interlocking or monitoring signal points. Kenxin Motor is an authorized Siemens distributor, providing genuine products, warranty, and selection consultation services.
Core Product Advantages and Features
High AC-1 resistive load capacity
The AC-1 has a rated current of up to 40A, making it suitable for resistive loads or non-motor switching applications, and can flexibly meet the needs of different circuits.
24V DC coil design
DC operating voltage compatible with battery-powered or DC control power supply systems, suitable for special control panel architectures.
Four sets of auxiliary contacts satisfy the requirement at once.
The 2NO+2NC configuration reduces the need for external auxiliary contact modules, simplifying wiring and panel design.
S0 chassis shared design
It shares installation dimensions and accessories with other products in the same series as 3RT2026, which facilitates material preparation and standardized management.
