Product details

Trip class and motor protection timing

The SIRIUS 3RU2116-1DB0-ZX95 mounts directly to the contactor via the S00 frame interface, saving DIN rail space in the panel.

Auxiliary contact and tripped indication

The integrated auxiliary switch carries a "Tripped" message, meaning the normally-open contact closes when the relay trips — this signal goes to a PLC input or a pilot light for fault annunciation. At 60 V DC the contact is rated 0.3 A — if your control circuit runs at this voltage, the DC arc extinction limits the switching capacity; stay within the rating for reliable fault indication.

Lifecycle stage is marked as current production — the 3RU2116-1DB0-ZX95 is an active catalog item in the Siemens SIRIUS portfolio. Same part, different passport — this order code carries the -ZX95 suffix, which is a Siemens-internal variant marking (often a special version or customer-specific configuration). The base 3RU2116-1DB0 is the standard catalog number; the -ZX95 suffix may affect packaging or documentation but the functional specs are identical to the base relay.

Frequently asked questions

What does the "Tripped" message on the 3RU2116-1DB0-ZX95 mean?

The integrated auxiliary contact is wired to signal a trip condition — when the relay opens due to overload, the contact changes state to indicate the motor has been disconnected. This is a dry contact rated for the voltages listed in the spec table, not a powered output.

What is the closest alternative to 3RU2116-1DB0-ZX95 in the SIRIUS family?

The base order code 3RU2116-1DB0 (without the -ZX95 suffix) is the standard catalog variant with identical electrical and mechanical specs. The -ZX95 suffix denotes a Siemens-internal variant marking — functionally the same relay, possibly differing in packaging or customer-specific documentation.
