Product details

What the ZX95 variant adds

The 3RU2116-0KC0-ZX95: The -ZX95 suffix on this 3RU2116 relay means it carries a note "for message Tripped" — the integrated auxiliary switch is wired to signal a trip condition back to the PLC or HMI, not just drop the contactor coil.

Trip Class 10 and motor protection

The thermal bimetallic release compensates for ambient temperature from -40 °C to +60 °C, so the trip curve stays accurate whether the panel is in a heated control room or an unheated warehouse. Rated voltage is 690 V, with power ratings of 0.37 kW at 400 V, 0.55 kW at 500 V, and 0.75 kW at 690 V in AC-3e duty.

S00 frame and spring-loaded terminals

Size S00 is the smallest SIRIUS overload relay frame — 45 mm wide, 70 mm deep, 87 mm tall — and mounts directly onto the contactor via the "contactor mounting" fastening method, no separate DIN rail bracket needed. Mounting position is any orientation, so it fits tight panel layouts without derating.

Frequently asked questions

What does the 'for message Tripped' note mean on this relay?

The -ZX95 variant includes an integrated auxiliary switch wired specifically to signal a trip condition, so the PLC or HMI gets a discrete 'tripped' status rather than just losing the motor run feedback.

What compliance documentation is available for this relay?

The substance prohibition date is 10/01/2009, indicating RoHS compliance.

Where can I buy 3RU2116-0KC0-ZX95 and get a price?
