Product details

The S00 frame size tells you it mates with the S00 contactor family and handles motor FLCs in the lower range of the SIRIUS line.

Mounts directly onto the contactor — the fastening method is contactor mounting, so no DIN rail bracket needed if you're snapping it onto a S00 contactor. The dimensions are compact: 45 mm wide, 87 mm tall, and 78 mm deep. That depth matters when you're calculating gland-plate clearance or panel-door swing. Side clearance to adjacent devices is 6 mm; zero clearance needed upwards, forwards, backwards, or downwards.

Terminals and wiring

Both main and auxiliary/control circuits use screw-type terminals. The solid wire capacity is 2× (0.5 … 1.5 mm²) and 2× (0.75 … 2.5 mm²); finely stranded with core-end processing matches the same ranges. For AWG on the auxiliary contacts, it accepts 2× (20 … 16) and 2× (18 … 14). That's enough for standard motor-circuit wiring and control-loop conductors. The front is finger-safe per IP20 — touch-safe for the panel builder but not for washdown environments.

Ratings that matter for the panel

Power dissipation is 2.2 W per pole — three poles means 6.6 W total heat to manage inside the enclosure. That's modest, but if you're packing a dozen of these in a sealed box, the thermal rise adds up. Auxiliary contact ratings: 1 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V. These are the currents the built-in auxiliary switch can break — useful for signaling the PLC or a status lamp. Shock resistance is 8g for 10 ms — fine for machine-mounted applications with moderate vibration.

Frequently asked questions

What compliance documentation does this part carry?

It carries ATEX approval DMT 98 ATEX G 001 for explosive gas atmospheres, is RoHS-compliant per substance prohibition date 07/01/2006, and has IP20 touch protection on the front. The reference code per IEC 81346-2 is F.

What are the key dimensions for panel layout?

Width is 45 mm, height is 87 mm, depth is 78 mm. Side clearance needed is 6 mm; zero clearance required upwards, forwards, backwards, or downwards.

What wire sizes does the terminal block accept?

Solid conductors: 2× (0.5 … 1.5 mm²) and 2× (0.75 … 2.5 mm²). Finely stranded with core-end processing matches the same ranges. For AWG on auxiliary contacts: 2× (20 … 16) and 2× (18 … 14). Both main and auxiliary circuits use screw-type terminals.

What does CLASS 10 mean on this overload relay?

CLASS 10 means the relay will trip within 10 seconds at 7.2 times the set current. This is the standard trip class for standard-duty induction motors — it protects the motor from sustained overload without nuisance-tripping during normal starting.
