Product Positioning

The 3RT1016-1MB42-0KT0 belongs to Siemens' SIRIUS "Coupling Contactor" series. Its coil features a 24V DC tolerance design, with an operating voltage range of 0.85 to 1.85 times the rated value. It can be directly driven by PLC digital outputs without additional relay circuitry. The main circuit maintains the standard S00 frame 9A, 4kW specifications and includes one set of normally closed auxiliary contacts, making it a reliable choice for connecting controllers and motor loads in automated control systems.

Core Product Advantages and Features

PLC direct drive coupling design

The coil operates within a range of 0.85 to 1.85 times its rated voltage and can be directly driven by PLC digital output signals.

9A/4kW main circuit

The AC-3 has a rated current of 9A and can switch 4kW three-phase motor loads at 400V.

24V DC coil

It adopts a DC coil design, making it suitable for integration with PLC or DC control systems.

1 set of normally closed auxiliary contacts

It has a built-in 1NC auxiliary contact, which can be used for status feedback or interlock protection circuits.

Screw terminal design

Both the main and auxiliary circuits use screw terminals, making wiring and maintenance quite convenient.

S00 Small Frame

It is compact and can be directly mounted on a 35mm standard DIN rail to save space in the distribution box.

3RT1017-1AF01

The 3RT1017-1AF01 and 1AF02 are both S00 frame, 12A/5.5kW contactors, with coils of 110V AC (50/60Hz). The difference is that the auxiliary contact is a set of normally open (1NO), suitable for operation indication or start interlock signal, with a mechanical life of 30 million cycles and screw terminal wiring.

3RT10161MB410KT0

The 3RT1016-1MB41-0KT0 and 1MB42-0KT0 belong to the same coupling contactor series. They are 24V DC coils with a range of 0.85 to 1.85 times the rated voltage and can be directly driven by a PLC. The difference is that the 3RT1016-1MB41-0KT0 has one set of normally open (1NO) auxiliary contacts, and the main circuit is AC-3 rated at 9A and 4kW at 400V, with screw terminals.

3RT10161BB443MA0

The 3RT1016-1BB44-3MA0 is the SIRIUS S00 contactor model with the most auxiliary contacts. It has four sets of permanently engaged contacts (2NO + 2NC) to meet interlocking, indicating, and feedback requirements. The main circuit is rated at 9A AC-3, 4kW at 400V, with a coil of 24V DC and a net weight of approximately 0.2kg, making it suitable for star-delta starting applications.
