Siemens 3RT2016-1SB42 Screw-connected contactor, DC coil, normally closed auxiliary contact

Product Positioning

The 3RT2016-1SB42 is a screw-terminal coupled contactor in the Siemens SIRIUS 3RT2016 series. Following the contact coding convention of the suffix "42" (consistent with the BB42, KB42, and VB42 in the same series), this product features one set of normally closed (NC) auxiliary contacts. The main circuit maintains the standard S00 frame specification of 3-pole AC-3 rated 9A, 4kW/400V. This coupled contactor's coil belongs to the DC control voltage family and can be directly driven by PLC or relay outputs. However, it is recommended to consult Kenxin Motors' sales personnel or check the latest manufacturer's catalog for the exact coil rated voltage before ordering to ensure complete compatibility with the field control circuit voltage. The terminals feature a traditional screw design, providing stable locking and suitable for industrial control enclosures requiring regular inspection and maintenance.

Core Product Advantages and Features

DC-coupled coil design

Belonging to the SIRIUS coupling contactor family, the coil is designed for DC control voltage and can be directly used with PLC or relay output circuits.

1 set of normally closed auxiliary contacts

According to contact code conventions, it is equipped with 1 NC auxiliary contact, which is suitable as a source of power failure protection, fault interlock or status feedback signal.

Screw-type terminal blocks

Both the main circuit and the control circuit adopt a screw terminal design, which provides stable locking force and facilitates on-site wiring and subsequent maintenance.

SIRIUS standard frame compatible

It adopts the same S00 chassis and AC-3 9A/4kW rated performance as the 3RT2016 series, and can share the same selection logic with accessories and auxiliary modules in the same series.
