Product details

The S00 frame size keeps it compact for 45 mm wide DIN-rail or panel mounting, and it is rated for a maximum of 690 V on the main circuit. The auxiliary contacts are integrated and rated for switching at various control voltages: 2 A at 24 V, 2 A at 230 V, 1 A at 400 V, and 0.75 A at 690 V, among others. This covers both 24 VDC PLC-level signals and 230 VAC pilot circuits without an extra interface relay.

The relay is designed for stand-alone installation — it does not require a separate base or adapter. Spring-loaded terminals on the main current circuit accept 2 × (0.5... 2.5 mm²) solid or stranded wire, and the screwdriver tip size is specified at 3.0 × 0.5 mm.

The relay carries a substance prohibitance date of 10/01/2009, aligning with early RoHS compliance.

Frequently asked questions

Where can I buy 3RU2116-1FC1 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ to confirm current availability and pricing at quote time.

Will 3RU2116-1FC1 drop into a panel specified around 3RT2015-2AP02?

The 3RU2116-1FC1 is a thermal overload relay, while 3RT2015-2AP02 is a contactor. They are designed to work together in the same SIRIUS system and share the S00 frame size, so the relay mounts directly onto the contactor or alongside it on the DIN rail without rewiring the main power circuit.

What is the note 'for message Tripped' on this component line?

The note indicates that the auxiliary contact position on the 3RU2116-1FC1 is labeled for the 'Tripped' message — the normally-closed contact that opens when the relay has tripped on overload, used to signal a fault condition to the PLC or annunciator.

What is 3RU2116-1FC1's listed depth?

The depth is 79 mm. Combined with a width of 45 mm and height of 102 mm, this is the standard S00 footprint.

What compliance documentation does Siemens provide for 3RU2116-1FC1?

The part carries a substance prohibitance date of 10/01/2009, indicating RoHS compliance from that date. Standard Siemens documentation includes the declaration of conformity and CE marking for the Low Voltage Directive.
