The relay is finger-safe (IP20 on the front) and carries ATEX approval (DMT 98 ATEX G 001) for use in potentially explosive gas atmospheres, so it can be deployed in Zone 2 or Zone 22 applications when paired with an appropriate contactor. Mounts directly onto a SIRIUS S00 contactor without additional hardware — no DIN rail needed. The mounting position allows a vertical surface with ±135° rotation and ±45° tilt front-to-back, giving panel layout flexibility. This zero-clearance top/bottom mounting means the relay can be stacked tight against other components in a crowded enclosure, but the 6 mm side gap must be maintained for heat dissipation. ## Wiring and conductor compatibility Main and auxiliary circuit terminals accept solid or finely stranded conductors with core-end processing: 2× (0.5... 1.5 mm²) and 2× (0.75... 2.5 mm²) per clamp. For AWG, the auxiliary contacts accept 2× (20... 16) and 2× (18... 14). This gives flexibility for both European metric and North American wiring practices. The screw-type terminals are the same as the main circuit terminals, so the same screwdriver and torque setting work across all connections — no tool change for the auxiliary wiring.","metaTitle":"Siemens 3RU1116-1DB0-ZW95 SIRIUS Thermal Overload Relay, CLA","metaDescription":"Siemens 3RU1116-1DB0-ZW95 SIRIUS thermal overload relay, CLASS 10 trip, S00 frame, 3-pole, contactor-mount, ATEX, finger-safe IP20.
