Rated for 3-pole main circuits with screw-type terminals on both the main and auxiliary/control circuits. Mounts directly to the contactor via the fastening method specified as contactor mounting, with a vertical mounting surface that allows ±135° rotation and ±45° tilt forward/backward — useful for tight panel layouts where the contactor assembly must be oriented to fit cable ducts or busbars. ## Contact Ratings and Auxiliary Circuit The auxiliary contact block carries rated currents that vary by control voltage: 3 A at 120 V, 2 A at 230 V, 1 A at 400 V, and 1 A at 24 V. Power dissipation per pole is 1.9 W, so total heat load in the enclosure is 5.7 W under continuous rated current — factor that into your panel thermal budget, especially in a sealed cabinet. Rated for 100 % relative humidity during operation — condensation is acceptable as long as the enclosure is rated for it. Carries ATEX type protection DMT 98 ATEX G 001, so it is approved for use in potentially explosive gas atmospheres when paired with an appropriate motor and enclosure. Surge voltage resistance is rated at 6 kV, and shock resistance at 8g for 10 ms. Substance prohibition date is 07/01/2006, indicating RoHS compliance per the EU directive effective that date. Main circuit terminals accept solid or finely stranded conductors with core-end processing: 2×(0.5…1.5 mm²) and 2×(0.75…2.5 mm²). AWG equivalents are 2×(20…16) and 2×(18…14), plus 2×12 AWG. Auxiliary contacts accept 2×(20…16) and 2×(18…14) AWG. Clearance distances: 0 mm upwards, forwards, and backwards; 6 mm at the side; 0 mm downwards. The zero-clearance top and bottom allow stacking contactors and relays in a tight vertical column without additional spacing.","metaTitle":"Siemens 3RU1116-1EB0-ZW98 SIRIUS Thermal Overload Relay, CLA","metaDescription":"Siemens SIRIUS 3RU1116-1EB0-ZW98 thermal overload relay, CLASS 10, size S00, 3-pole, screw terminals, IP20 front, ATEX, current production.
