SIRIUS 3RP20 timing relays

SIRIUS 3RP20 electronic timing relays for use in control systems and mechanical engineering with:

• 1 or 2 CO contacts
• Multifunction or monofunction
• Wide voltage range or combination voltage
• Single or selectable time setting ranges
• Switch position indication and voltage indication by LED

Standards

The timing relays comply with:

• IEC 60721-3-3 “Ambient conditions”
• IEC 61812-1 "Specified time relays for industrial use"
• IEC 61000-6-2 and EN 61000-6-4 "Electromagnetic compatibility"
• IEC 60947-5-1 "Low-voltage switchgear and controlgear"
• IEC 60947-1, Appendix N "Electrical Isolation"

Multifunction

The functions of the multifunctional timing relay 3RP2005 can be set by means of the function selector switch. Inscription labels can be used to adapt the timing relay clearly and unmistakably for different functions. The corresponding labels can be ordered as accessories. The same potential must be applied to terminals A. and B. For functions see label set 3RP2901.

Note:

The activation of loads parallel to the start input is not permissible when using AC control voltage (see diagrams).
