For auxiliary and control circuits, screw terminals accept 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) finely stranded with ferrules; main circuit terminals accept 2x (16 to 12 AWG) or 2x (14 to 8 AWG). The mounting position allows ±135° rotation and ±45° tilt on a vertical surface, giving flexibility in tight panel layouts. The relay carries ATEX approval (DMT 98 ATEX G 001) for use in potentially explosive atmospheres, and its substance prohibitance date of 07/01/2006 aligns with RoHS compliance. Surge voltage resistance is rated at 6 kV, and shock resistance is 8g for 10 ms — robust for industrial panel vibration.","metaTitle":"Siemens 3RU1126-1GB0-ZX95 SIRIUS thermal overload relay, CLA","metaDescription":"Siemens SIRIUS 3RU1126-1GB0-ZX95 thermal overload relay, CLASS 10 trip, S0 frame, IP20 front, current production.
