Siemens 3RT2 Series Contactor, 11kW Power, 24V Coil Voltage - 3RT2026-1BB44-3MA0


This contactor is a compact, three-pole device designed for motor control and reversing applications in industrial installations. It operates with a 24 V DC Coil and is rated for AC loads up to 690 V, providing switching capability for motors up to 11 kW at 400 V in AC-3 duty. The unit mounts Snap-on to a 35 mm DIN rail and includes a captive auxiliary switch Block with two normally open and two normally closed auxiliary contacts for control logic integration.

Features and Benefits:


• 25 A AC-3 operational current for sustained motor switching
• 24 V DC Coil reduces control supply complexity
• 2 NO 2 NC auxiliary contacts for monitoring and interlocking
• Screw terminals provide secure conductor connections
• IP20 front protection for safe panel access

Applications


• Used for forward/reverse motor control in conveyor systems
• Suitable for three-phase motor starters in machine tools
• Ideal for control panels requiring Compact contactors
• Can be used with contactor blocks requiring auxiliary contacts
• Used for switching 11 kW motors at 400 V in industrial plants

What temperature range can it operate within?


It is rated for operation between -25 °C and +60 °C.

How is the device mounted in a control cabinet?


It snaps onto a 35 mm DIN rail and supports side-by-side mounting.

What conductor sizes are supported on the main terminals?


Main contacts accept solid or stranded conductors from 1…10 mm² and two conductors per Terminal where specified.

What electrical protection ratings apply to auxiliary contacts?


Auxiliary contacts are rated up to 10 A for AC-12 and up to 6 A at 230 V for AC-15 operations.
