Product Positioning

The 3RT2026-2BB44-3MA0 belongs to the Siemens SIRIUS 3RT2026 series S0 housing contactor. Its main circuit has an AC-3 rated capacity of 25A, corresponding to 11kW at 400V. Like the 1BB44/1DB44 models in the same series, it uses a 24V DC operating coil and has four sets of auxiliary contacts (2NO + 2NC). It is suitable for DC control circuits and automation panels requiring a large number of feedback points. This is a mass-produced model in the 3RT2026 family with a specific ordering suffix (-3MA0). Kenxin Motors can assist in confirming actual inventory and delivery time.

Core Product Advantages and Features
24V DC operating coil
DC coil designs are suitable for control circuits powered by DC power supplies, such as battery backup or DC panel systems.
Four sets of auxiliary contact configuration
The 2NO+2NC configuration is implemented in one step, reducing the cost and wiring complexity of adding additional auxiliary contact modules.
S0 casing miniaturization
It shares the same housing and accessory system as the 3RT2026/3RT2027 series, which facilitates panel standardization and material management.
11kW small and medium power motor applications
The AC-3 is rated at 25A and 11kW/400V, suitable for the start-up and shut-down control of small and medium power motors such as conveyor belts, small pumps, and fans.
