The S0 frame size mates with Siemens 3RT2 contactors in the same size class. Fastened by contactor mounting — clips onto the contactor body, no extra panel space. Clearance requirements: 0 mm upwards, 0 mm forwards, 0 mm backwards, 0 mm downwards, 6 mm at the side. ## Wire Terminations Main circuit terminals accept solid or finely stranded wire with core-end processing: 2x (0.5... 1.5 mm²) and 2x (0.75... 2.5 mm²). Auxiliary/control circuit terminals use the same screw-type and wire ranges. AWG equivalents: 2x (20... 16) and 2x (18... 14). Operating temperature range -20 to +70 °C, storage and transport -55 to +80 °C. Relative humidity up to 100% during operation. Shock resistance 8g / 10 ms. Surge voltage resistance rated at 6 kV. Auxiliary contact ratings per pole: 2.2 W thermal dissipation. Switching capacities: 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, 1 A at 400 V. These are the make/break ratings for the built-in auxiliary contacts.","metaTitle":"Siemens 3RU1126-1JB0-ZW97 SIRIUS Thermal Overload Relay, Siz","metaDescription":"Siemens 3RU1126-1JB0-ZW97 SIRIUS thermal overload relay, Size S0, Trip Class 10, IP20 front, 96 mm depth.
