At 8 A rated current, this relay covers the lower end of the S00 frame. It is rated for a 690 V main circuit, 50/60 Hz, and handles auxiliary contacts rated at 3 A at 24 V and 2 A at 230 V. The total typical power loss is 6.6 W — a figure to check against your enclosure's thermal budget. The relay is IP20 at the front and terminals, so it is suitable for enclosed panels only, not washdown areas.","metaTitle":"Siemens 3RU7116-1HB0 SIRIUS Thermal Overload Relay, 8 A, Cla","metaDescription":"Siemens SIRIUS 3RU7116-1HB0 thermal overload relay, 8 A rated current, Class 10 trip, size S00, IP20.
