Both main and auxiliary/control circuits use screw-type terminals — no spring-cage adapters needed, but you'll want a Pozidriv bit on the torque driver. Mounting position is flexible: vertical surface with ±135° rotation or ±45° tilt front/back. That zero-clearance top and bottom means you can stack relays tight in a multi-row panel without derating for airflow — handy when you're filling a crowded enclosure. Operating temperature range is -20 … +70 °C, storage and transport -55 … +80 °C. The relay carries IP20 finger-safe touch protection on the front and is approved for ATEX Zone 2 / Zone 22 (DMT 98 ATEX G 001). Surge voltage resistance is rated at 6 kV. Shock resistance is 8g / 10 ms. Relative humidity during operation can hit 100 % — no derating needed for condensing environments. ## Auxiliary contact ratings Auxiliary contact ratings cover common control voltages: 1 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V. For DC applications: 0.22 A at 110 V, 0.22 A at 125 V, 0.11 A at 220 V. Power dissipation per pole is 2.2 W — factor that into your enclosure thermal budget if you're running near the upper ambient limit.","metaTitle":"Siemens 3RU1116-1JB0-ZW95 SIRIUS Thermal Overload Relay, CLA","metaDescription":"Siemens 3RU1116-1JB0-ZW95 SIRIUS thermal overload relay, CLASS 10, size S00, 3-pole, 78 mm depth, IP20, ATEX.
