Product details

Rated for main circuit voltages up to 690 V, it handles the common 400 V, 480 V, and 600 V industrial supplies. The auxiliary switch is integrated, and the relay itself provides a "Tripped" signal contact — the note on the order code identifies this variant as having a specific message for that tripped state, useful for remote annunciation in a PLC or HMI.

Mounts directly onto a contactor via the contactor mounting fastening method — no separate DIN-rail footprint needed, which saves panel space. The screw-type terminals on the main current circuit accept solid or stranded conductors: 2× (0.5 to 1.5 mm²) or 2× (0.75 to 2.5 mm²). The screwdriver shaft requires a 5–6 mm diameter with a Pozidriv PZ 2 tip. Mounting position is any, giving flexibility in tight enclosures. The relay's dimensions — 45 mm wide, 76 mm high, 70 mm deep — fit within the standard S00 contactor envelope.

Temperature compensation is active from -40 to +60 °C, ensuring the trip curve stays accurate across the working range. The relay carries a substance prohibitance date of 10/01/2009, indicating RoHS compliance. MTTF with high demand rate is 2,280 years, reflecting the robust design of the SIRIUS platform for continuous industrial duty.

Frequently asked questions

What is the trip class and what does it mean?

Class 10 means the relay will trip within 10 seconds at 7.2× the full-load current setting. This matches the thermal withstand of standard IEC induction motors during a locked-rotor condition.

What is the significance of the 'Tripped' message note on this variant?

The order code suffix -ZX95 indicates a special version where the auxiliary contact provides a specific message for the tripped state, enabling direct integration with monitoring systems that read that signal.

What are the main voltage ratings?

Rated value is 690 V for the main circuit. Specific motor power ratings at common voltages: 2.2 kW at 400 V, 3 kW at 500 V, 4 kW at 690 V. Current ratings at 480 V and 600 V are both 6.3 A.
