Product details

Trip indication and motor protection logic

The 3RU2116-1DC0-ZX95 carries a note for message "Tripped" — the integrated auxiliary switch signals the PLC or HMI directly when the relay operates, so the control system knows the motor dropped off without polling the overload via the power circuit.

Auxiliary contact ratings for signal compatibility

At 60 V the contact is rated 0.3 A, and at 110 V or 125 V it carries 0.22 A — useful for legacy 110 VDC control circuits or specialised 60 V signalling.

S00 footprint and wiring

Size S00 with 70 mm depth, 45 mm width, and 87 mm height — this mounts directly onto the matching S00 contactor (e.g. 3RT201) without extra brackets, saving DIN-rail space.

The relay carries a substance prohibitance date of 10/01/2009, indicating RoHS compliance from that date onward.

Frequently asked questions

What does the note 'for message Tripped' mean on the 3RU2116-1DC0-ZX95?

It means the integrated auxiliary switch provides a dedicated signal output that changes state when the overload relay trips, so the control system receives a direct 'tripped' indication without needing to sense motor current separately.

What is the closest alternative to the 3RU2116-1DC0-ZX95 in the SIRIUS family?

The standard 3RU2116-1DC0 (without the -ZX95 suffix) is the base variant. The -ZX95 suffix typically indicates a special version or custom configuration — confirm the specific BOM requirement before substituting.
