Product details

The 45 mm width and 78 mm depth mean it fits the standard 45 mm-wide DIN-rail footprint — no need to re-space the panel if you're swapping into an existing SIRIUS S00 slot. Screw-type terminals on the main circuit accept 1x (20…16) or 1x (18…14) AWG solid, plus 1x 12 AWG; auxiliary/control terminals take 2x (0.5…1.5 mm²) or 2x (0.75…2.5 mm²) solid or finely stranded with ferrule.

Mounts stand-alone or directly onto the contactor. Shock rated at 8g for 10 ms, so it'll survive the occasional forklift bump to the panel door. The ATEX approval (DMT 98 ATEX G 001) means it's listed for use in potentially explosive atmospheres when paired with the right upstream protection — a detail the MRO planner needs if the line is in a classified area.

Frequently asked questions

What are the key dimensions for panel layout?

Width is 45 mm, height 87 mm, depth 78 mm. That's the standard S00 footprint, so it occupies one 45 mm-wide DIN-rail slot.

What wire sizes does the terminal block accept?

Main circuit screw terminals accept 1x (20…16), 1x (18…14), or 1x 12 AWG solid. Auxiliary/control terminals accept 2x (0.5…1.5 mm²) or 2x (0.75…2.5 mm²) solid or finely stranded with ferrule.

Does this relay have ATEX approval?

Yes, it carries DMT 98 ATEX G 001 certification for use in potentially explosive atmospheres when properly integrated.
