The 3-pole main current circuit uses screw-type terminals accepting solid wire 2x (0.5... 1.5 mm²) and 2x (0.75... 2.5 mm²), or AWG 1x (20...16), 1x (18...14), 1x 12. The auxiliary and control circuit also uses screw terminals with the same wire ranges. Each pole dissipates 2.2 W, so for a three-pole relay the total thermal dissipation is 6.6 W — factor that into your enclosure thermal budget. The auxiliary contact ratings cover common control voltages: 1 A at 24 V, 3 A at 120 V, 2 A at 230 V, and 1 A at 400 V. The 3RU1116-1GB1 carries ATEX approval DMT 98 ATEX G 001, permitting use in potentially explosive gas atmospheres. It withstands 100 % relative humidity during operation and shock of 8g for 10 ms. The mounting position is flexible: it can be mounted on a vertical surface with ±135° rotation and ±45° tilt front-to-back. RoHS compliance is indicated by a substance prohibitance date of 01.07.2006.","metaTitle":"Siemens 3RU1116-1GB1 SIRIUS Thermal Overload Relay, CLASS 10","metaDescription":"Siemens 3RU1116-1GB1 SIRIUS thermal overload relay, CLASS 10 trip, size S00, 3-pole, screw terminals, IP20 front.
