The 45 mm width and 87 mm height fit standard DIN-rail spacing; depth is 78 mm. Side clearance of 6 mm is required for heat dissipation — no tight nesting against adjacent devices. Power dissipation at AC hot operating state is 6.6 W total, 2.2 W per pole. That thermal load must be factored into enclosure sizing, especially in a densely populated panel. The relay is rated for ambient operation from -20 to +70 °C and storage/transport from -55 to +80 °C. ## Environmental and compliance profile The 3RU1116-1KB1 carries ATEX type protection DMT 98 ATEX G 001, qualifying it for use in potentially explosive gas atmospheres when paired with an appropriate contactor. Surge voltage resistance is rated at 6 kV; shock resistance is 8g for 10 ms. Operating humidity tolerance is 100%, covering condensing environments.","metaTitle":"Siemens 3RU1116-1KB1 SIRIUS Thermal Overload Relay, CLASS 10","metaDescription":"Siemens 3RU1116-1KB1 SIRIUS thermal overload relay, CLASS 10 trip, size S00, screw terminals, IP20.
