For most conveyor, pump, and fan drives, this is the right call. The control circuit draws 1 A at 24 V, 3 A at 120 V, and 2 A at 230 V — so it's compatible with common control voltages across North American and European panels. This relay mounts directly onto a SIRIUS contactor — no DIN rail bracket needed, no extra hardware. Clearance requirements are minimal: 0 mm upwards, forwards, backwards, and downwards, with only 6 mm needed at the side. That means you can pack relays side-by-side without worrying about heat buildup from the 2.2 W per pole power loss — just keep the side gap. The main circuit accepts solid conductors: 2x (0.5...1.5 mm²) and 2x (0.75...2.5 mm²), plus AWG equivalents. Auxiliary contacts take 2x (20...16) and 2x (18...14) AWG. Finely stranded with core-end processing uses the same ranges. Relative humidity up to 100 % is allowed, so condensation inside a non-heated enclosure won't necessarily cause issues. Shock resistance is rated at 8g for 10 ms — typical for industrial machinery vibration. It carries ATEX approval (DMT 98 ATEX G 001), so it's suitable for use in potentially explosive atmospheres when paired with the correct contactor and upstream protection.","metaTitle":"Siemens 3RU1116-1GB0-ZW98 SIRIUS Thermal Overload Relay, Cla","metaDescription":"Siemens 3RU1116-1GB0-ZW98 SIRIUS thermal overload relay, 3-pole, Size S00, Class 10 trip.
