The IP20 front protection and 100 % relative humidity rating make it suitable for enclosed panels in washdown or high-humidity environments, though the relay body itself is not rated for direct spray. ATEX certification (DMT 98 ATEX G 001) confirms it meets the essential health and safety requirements for equipment in potentially explosive atmospheres. ## Mounting and integration — contactor mounting, no extra DIN rail Mounts directly onto the S00 contactor via the fastening method, saving a DIN rail position. The mounting position allows ±135° rotation and ±45° tilt forward/backward, so it adapts to tight enclosure layouts without special brackets. Clearance needs: 0 mm upwards, forwards, backwards, and downwards — the side clearance is 6 mm to adjacent devices for heat dissipation. Wire termination accepts 2x (0.5... 1.5 mm²) or 2x (0.75... 2.5 mm²) solid or finely stranded with ferrule, plus AWG equivalents. Auxiliary and control circuits use the same screw-type terminals.","metaTitle":"Siemens 3RU1116-1FB0-ZW95 SIRIUS Thermal Overload Relay, Siz","metaDescription":"Siemens 3RU1116-1FB0-ZW95 SIRIUS thermal overload relay for motor protection.
