Product details

The integrated auxiliary switch is rated across multiple control voltages: 2 A at 24 V and 230 V, 3 A at 120 V, 1 A at 400 V, and 0.75 A at 690 V. These cover most PLC and relay interface voltages used in panel designs — the 120 V 3 A rating is the highest current point, useful for driving contactor coils directly.

Mounts directly onto the contactor via the fastening method specified — no DIN rail required, which saves panel width. Main circuit connections use screw-type terminals accepting 2× (0.5…1.5 mm²) or 2× (0.75…2.5 mm²) solid or stranded wire. The screwdriver tip is Pozidriv PZ2 with a shaft diameter of 5…6 mm. Dimensions: 45 mm wide, 76 mm high, 70 mm deep.

Operating temperature range is -40…+70 °C with temperature compensation active from -40…+60 °C, so the relay maintains accurate trip characteristics across typical industrial ambient conditions. Storage and transport range is -55…+80 °C. The part is RoHS-compliant per the substance prohibition date of 10/01/2009.

Frequently asked questions

What does the note 'for message Tripped' mean?

The part carries a note indicating it is used to signal a tripped condition — the auxiliary switch changes state when the relay trips, providing a remote indication to a PLC or annunciator.

What is the depth of the 3RU2116-4AB0?

The depth is 70 mm, with a width of 45 mm and height of 76 mm.

What compliance documentation is available?

The part is RoHS-compliant per the substance prohibition date of 10/01/2009. Additional certifications (UL, CSA, CE) are typical for the SIRIUS family but are not listed in this record.
