Rated for use up to 690 V, with a 1.5 kW motor at 400 V and 3 kW at 690 V. The auxiliary switch is integrated, and the main circuit connects via spring-loaded terminals — no screwdriver needed for the power wires, which saves time during panel build or swap-out. Fastened for stand-alone installation — it does not require a contactor base. The spring-loaded terminals accept 2x (0.5 to 2.5 mm²) solid or stranded wire. For the auxiliary circuit, a 3 mm diameter screwdriver shaft is needed for the screw terminals. ## Ratings at a glance Auxiliary contact ratings: 2 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V, 0.75 A at 690 V. Also rated 0.3 A at 60 V, 0.22 A at 110 V and 125 V, and 0.11 A at 220 V. Power dissipation per pole is 1.9 W. Dimensions: 45 mm wide, 102 mm high, 79 mm deep.","metaTitle":"Siemens 3RU2116-1EC1 SIRIUS thermal overload relay, Class 10","metaDescription":"Siemens 3RU2116-1EC1 SIRIUS thermal overload relay, Class 10, size S00, spring-loaded terminals, 690 V rated, current lifecycle.
