3.2 Device description
Electronic timing relays are used in control, starting, and protective circuits for all switching
operations involving time delays. Their fully developed concept and space-saving, compact
design make the SIRIUS 3RP timing relays ideal modules for control cabinet, switchgear and
control manufacturers in the industry.
Thanks to their slim-line, space-saving design from 17.5 mm, 3RP25 timing relays are
especially suitable for use in smaller control boxes, such as heating, ventilation and air-
conditioning systems, and in compressors. All 3RP25 timing relays in this enclosure version
are suitable for snapping onto TH35 mounting rails in accordance with IEC60175.
Benefit
● Transparent program with seven basic units for the 3RP timing relay
● Logistical advantages provided by versions with wide voltage range and wide setting
range
● No tools required for assembly or disassembly on standard mounting rails
● Cadmium-free relay contacts
● Recyclable, halogen-free enclosure
● Optimum price/performance ratio
● Timing relays in 17.5 mm width offer more space in the control cabinet
● Environmentally friendly laser inscription instead of printing containing solvents
● Hard gold-plated relay contacts for optimum interaction with electronic controls
● Versions with screw-type connection or alternatively with spring-loaded/push-in
technology
