Siemens 3RT1 Series Contactor, 24V Coil voltage, 150A Contact Current - 3RT1055-6AB36


This contactor is a three-pole device designed for motor control in industrial installations, providing switching capability for AC and DC control supplies. It operates with a 24V ac/dc control Coil and is rated for heavy-duty switching of motors up to 75 kW at 400V AC. The unit accommodates screw connections for control and auxiliary circuits and is intended for vertical mounting in switchgear or distribution panels.

Features and Benefits:


• 150A operational current enables heavy-duty motor switching
• 75 kW power rating supports high-power motor loads
• 24V ac/dc Coil reduces control-voltage complexity
• 2NO 2NC auxiliary contacts deliver local signalling and interlock
• Screw Terminal auxiliary connections simplify secure wiring

Applications


• Suitable for motor starters in industrial plants
• Used with busbar main circuits in control panels
• Ideal for large pump and compressor motor control
• Can be used for AC-3 switching of three-phase motors
• Used for retrofit of vertical-mount control assemblies

What environmental temperatures can it tolerate during operation?


It is rated to operate between -25°C and +60°C.

Which connection types are provided for the main and auxiliary circuits?


The main circuit uses a connection bar while auxiliary and control circuits use screw-type terminals.

What are the short-time withstand current capabilities?


It withstands up to 2727A for 1 s, 1831A for 5 s, and 1300A for 10 s in cold condition at 40°C.

How many mechanical operations can be expected from the contactor?


The contactor has a typical mechanical service life of 10,000,000 operating cycles.

What ingress protection and touch protection are available on the front?


Front protection is IP00 normally, and IP20 with a box terminal/cover providing finger-safe access.
