The front face carries IP20 protection; the relay carries ATEX approval DMT 98 ATEX G 001 for use in potentially explosive atmospheres. ## Dimensions and Mounting Clearances The relay occupies a footprint of 45 mm width, 97 mm height, and 96 mm depth. For panel layout planning, the required clearances to adjacent components are: 0 mm upwards, 0 mm forwards, 0 mm backwards, 0 mm downwards, and 6 mm at the side. The mounting position allows a vertical mounting surface with ±135° rotation and ±45° tilt to the front and back. ## Electrical Ratings and Auxiliary Contact Capacity The auxiliary contact ratings are specified per voltage: 1 A at 24 V, 0.22 A at 110 V, 3 A at 120 V, 0.22 A at 125 V, 0.11 A at 220 V, 2 A at 230 V, and 1 A at 400 V. Power dissipation per pole is 2.7 W. Relative humidity during operation is rated at 100 %. Shock resistance is 8 g for 10 ms. The relay is designed for use in environments with 100 % relative humidity and is ATEX approved for explosive atmospheres. ## Terminal Specifications and Wiring Main current circuit terminals accept solid conductors: 2x (0.5... 1.5 mm²) and 2x (0.75... 2.5 mm²); AWG equivalents: 2x (16... 12) and 2x (14... 8). AWG: 2x (20... 16) and 2x (18... 14). Finely stranded conductors with core end processing are also accommodated: 2x (0.5... 1.5 mm²) and 2x (0.75... 2.5 mm²).","metaTitle":"Siemens 3RU1126-4DB0-ZX95 SIRIUS Thermal Overload Relay, Siz","metaDescription":"Siemens 3RU1126-4DB0-ZX95 SIRIUS thermal overload relay, Size S0, CLASS 10 trip, 3-pole, screw terminals, IP20 front, ATEX approved, 96 mm depth.
