Siemens 3RT1916-2FK31 Timer Module Ac Dc

Product Description

The SIEMENS 3RT1916-2FK31 is an AC/DC timer module designed for use with compatible Siemens contactor assemblies in industrial and commercial control applications. This auxiliary timing block mounts directly onto a base contactor to add time-delay functionality to motor control, HVAC, and other load-switching circuits. It provides timed-control sequences without requiring a separate timing relay, keeping panel layouts compact and wiring straightforward. Licensed electricians and industrial controls technicians are the typical installers for this component in motor control centers, switchgear panels, and automated HVAC systems.

This timer module is suited for both residential-commercial HVAC control panels and light industrial applications where timed contactor operation is required. It is compatible with AC and DC control circuits, making it versatile across a range of panel configurations. The compact form factor allows it to fit in tight enclosure layouts without consuming additional DIN rail space beyond the base contactor footprint.

Key Features

• Accepts both AC and DC control voltage inputs for flexible circuit integration
• Direct-mount design attaches to compatible Siemens contactor bodies without additional hardware
• Compact profile minimizes enclosure space requirements
• Adds timed-delay switching functionality to existing contactor installations
• Lightweight construction at 0.05 pounds for easy panel handling

Compatibility

Designed as an OEM-style add-on timer block for compatible Siemens contactor assemblies in AC and DC control circuit applications. Consult the Siemens 3RT contactor series documentation to confirm fitment with your specific base contactor model before ordering.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC guidelines and local electrical codes. De-energize and lock out the panel completely before attaching or removing this module from any contactor assembly. Verify control voltage compatibility between the timer module and the existing circuit before energizing. Do not exceed the rated electrical parameters of the base contactor when integrating this timing accessory.
