Product Identification and Function
The 3RU1116-0FB0-ZX95: This relay provides Class 10 trip protection, meaning it will trip within 10 seconds at 7.2 times the full-load current setting, a standard for standard-duty motor starting applications where the start time is under 10 seconds. It is certified for use in potentially explosive atmospheres under DMT 98 ATEX G 001, making it suitable for integration into Ex-certified motor starter assemblies.
Electrical and Mechanical Ratings
The main current circuit is rated for 3 poles, with screw-type terminals accepting solid conductors of 2x (0.5... 1.5 mm²) and 2x (0.75... 2.5 mm²), or finely stranded wire with core end processing in the same ranges. AWG equivalents for the main contacts are 2x (20... 16), 2x (18... 14), and 2x 12. Auxiliary and control circuits also use screw-type terminals, with AWG capacity of 2x (20... 16) and 2x (18... 14). The auxiliary contacts are rated for switching at various control voltages: 1 A at 24 V, 3 A at 120 V, 2 A at 230 V, and 1 A at 400 V, among others. Power dissipation per pole is 1.6 W, which should be factored into the thermal budget of the enclosure. The relay is rated for a surge voltage resistance of 6 kV.
Environmental and Mounting Specifications
The device has an IP20 protection rating on the front, suitable for installation within a locked or tool-accessible enclosure. It can operate in ambient temperatures from -20 to +70 °C, with storage and transport limits from -55 to +80 °C. It is rated for 100% relative humidity during operation. Mounting is via contactor mounting (direct attachment to a compatible SIRIUS contactor). The mounting position allows for a vertical mounting surface with +/-135° rotation and +/-45° tilt to the front and back. Required clearances are: 0 mm upwards, forwards, backwards, and downwards; 6 mm at the side. The relay is shock-resistant to 8g for 10 ms, per the specification.
Physical Dimensions and Compliance
The physical dimensions are 78 mm depth, 45 mm width, and 87 mm height, fitting the S00 form factor for compact panel layouts. The reference code per IEC 81346-2 is F, indicating a protective device in the function-oriented designation system. The substance prohibition date per RoHS-like compliance is listed as 07/01/2006.
