Wire range accepts 2x (0.5…1.5 mm²) solid/stranded or 2x (0.75…2.5 mm²) with ferruled ends. Torque for main circuit screws: 3–4.5 N·m; auxiliary contacts: 0.8–1.2 N·m. ## Electrical ratings Three-pole main circuit, AC/DC voltage type. Auxiliary contacts rated 1 A at DC-13 / 24 V. Surge voltage withstand 6 kV. Ambient operating temperature -20 to +55 °C; transport -25 to +70 °C. Installation altitude up to 2000 m above sea level.","metaTitle":"Siemens 3RU7136-1HB0 SIRIUS Thermal Overload Relay, 8 A, Cla","metaDescription":"Siemens 3RU7136-1HB0 SIRIUS thermal overload relay, 8 A rated current, Class 10 trip, 690 V, screw terminals, IP20 front.
