SIRIUS 3RP20/25 and 7PV15 Timing Relays
for DIN rail mounting
Electronic timing relays are employed for all time-delayed switching processes in control, starting, protection and regulation circuits. Thanks to their elaborate operating concept and space-saving, compact design, the 3RP20 / 25 timing relays represent ideal timing devices for manufacturers of industrial control cabinets, power distribution boards and controls.
For use in industrial applications
The new SIRIUS 3RP25 timing relay is characterized by its compact housing design and new additional functions. Due to its increased range of up to 27 functions in a uniform wide voltage range from 12 to 240 V AC/DC, it provides a multitude of functions in the smallest of spaces. All this makes the SIRIUS 3RP25 a flexible, multifunctional time relay for all standard applications worldwide.
For building technology applications:
With their narrow design, the 7PV15 timing relays are particularly suitable for applications in heaters, fans, air conditioning systems and compressors.
SIRIUS 3RA2811/12/16 Function Modules
for mounting on 3RT2 contactors
The function modules facilitate the assembly of starters and contactor combinations for direct and star-delta start-up. They comprise all important control functions required for the respective feeder – e.g. timing and electric interlocking function. The function modules, which act as timing relays, can be rapidly and easily mounted on SIRIUS contactors – without laborious wiring. They support contactor switching both with ON and OFF delay.
SIRIUS 3RA2813/14/15 Time-Delayed Auxiliary Switches
for mounting on 3RT2 contactors
The electronically delayed auxiliary switches for mounting on contactors are dimensioned for contactor coil voltages from 24 to 240 V AC/DC (wide voltage). Auxiliary switches for control and status signals are employed especially for the switching of very small signals for electronic applications. They for example serve pump or fan over-travel similar to OFF delay timing relays or the delayed switch-on of a gate drive. Both the electrical and mechanical connection are realized by simply snapping the device on and locking it. A varistor is integrated in the time-delayed auxiliary switch for the attenuation of switching overvoltages in the contactor coil.
