It provides Class 10 trip protection for three-phase motor circuits, with screw-type terminals on both the main and auxiliary/control circuits. The IP20 front protection keeps panel internals safe during operation, and the DMT 98 ATEX G 001 approval qualifies it for use in potentially explosive atmospheres — a key differentiator from standard overload relays. ## Mounting and integration — direct-fit on 3RT2 contactors Fastening method is contactor mounting, meaning it snaps directly onto the matching SIRIUS 3RT2 contactor without additional DIN rail space. Mounting position is flexible: vertical mounting surface with ±135° rotation and ±45° tilt to front/back, so panel layout isn't locked into a single orientation. Clearance requirements are minimal — 0 mm upwards, forwards, backwards, and downwards — with only 6 mm needed at the side. This zero-clearance design lets you pack assemblies tight on the DIN rail. ## Electrical ratings and trip performance Rated for 3-pole main current circuits with a per-pole power loss of 2.2 W. 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. Relative humidity during operation can reach 100 % — suitable for unconditioned enclosures. Shock resistance is rated at 8g for 10 ms, so it holds up to vibration from contactors and motor starters in the same panel. ## Wiring and terminal capacity Solid wire capacity is 2x (0.5... 1.5 mm²) and 2x (0.75... 2.5 mm²), with the same spec for finely stranded with core end processing. AWG equivalents: main contacts accept 2x (20... 16), 2x (18... 14), and 2x 12; auxiliary contacts accept 2x (20... 16) and 2x (18... 14). The 78 mm depth and 87 mm height fit standard S00 panel layouts.","metaTitle":"Siemens 3RU1116-1JB0-ZX95 SIRIUS Thermal Overload Relay, Siz","metaDescription":"Siemens SIRIUS 3RU1116-1JB0-ZX95 thermal overload relay, Size S00, Class 10 trip, 3-pole, screw terminals, IP20 front, ATEX approved.
