IP20 on the front — finger-safe from the panel face, but the relay body itself isn't sealed; keep it inside an enclosure. The ATEX approval is the real differentiator here: DMT 98 ATEX G 001, so this relay is certified for use in potentially explosive gas atmospheres. That's not common on a standard S00 overload — if your BOM calls for ATEX, this is the compliance document that clears the panel inspector. The 6 kV surge voltage rating gives headroom on industrial mains with poor power quality. The relay is sized for the S00 contactor frame — 45 mm wide, 87 mm tall, 78 mm deep. Clearance requirements are tight: zero mm upward, forward, backward, and downward, 6 mm to the side. That means you can pack these relays side-by-side on a contactor rail with no extra breathing space in most directions, but you do need that 6 mm lateral gap for heat dissipation. Each pole dissipates 1.9 W — in a dense panel, add that up across multiple relays to check the internal temperature rise stays under the -20 to +70 °C operating range. Wire sizes are given for both solid and finely stranded with ferrule: 2× (0.5…1.5 mm²) and 2× (0.75…2.5 mm²) per clamp. AWG equivalents are 2× (20…16), 2× (18…14), and 2× 12 for the main circuit; auxiliary contacts take 2× (20…16) and 2× (18…14). The contactor-mounting fastening method means you don't need a separate base — it clips directly onto the matching SIRIUS contactor.","metaTitle":"Siemens 3RU1116-1DB0-ZW97 SIRIUS thermal overload relay, Cla","metaDescription":"Siemens SIRIUS 3RU1116-1DB0-ZW97 thermal overload relay, Size S00, Trip Class 10, 3-pole, screw terminals, IP20.
