The relay carries ATEX approval (DMT 98 ATEX G 001), so it is accepted in explosive-gas atmospheres when installed within the certified system boundary — relevant for petrochemical or grain-handling lines where the motor branch must not become an ignition source. Surge voltage resistance rated at 6 kV provides clearance for industrial networks where switching transients are common. The IP20 front protection means it is finger-safe when installed in an enclosure. Mounting position is flexible: the relay can be installed on a vertical surface with ±135° rotation and ±45° tilt forward/backward, which helps when the contactor is oriented awkwardly inside a crowded panel. Zero clearance required upwards, forwards, backwards, and downwards; only 6 mm side clearance is needed. Wire sizes accepted: main circuit terminals take 2× (0.5…1.5 mm²) solid or 2× (0.75…2.5 mm²) solid, plus the AWG equivalents (2× 20…16, 2× 18…14, 2× 12). Auxiliary control circuit terminals accept 2× (20…16) and 2× (18…14) AWG. Finely stranded wire with ferrule is also supported with the same cross-sections. Dimensions: 87 mm height, 45 mm width, 78 mm depth — compact enough for the S00 frame size, which is the smallest SIRIUS overload relay footprint. The 78 mm depth means it will fit most standard-depth enclosures without interfering with the door or backplane wiring.","metaTitle":"Siemens 3RU1116-1AB0-ZW95 SIRIUS Thermal Overload Relay, Siz","metaDescription":"Siemens 3RU1116-1AB0-ZW95 SIRIUS thermal overload relay, Size S00, Trip Class 10, 3 poles, screw terminals, IP20, ATEX approved.
