3RP2025-1AN30 — Siemens SIRIUS 3RP Multifunction Timer Relay
The Siemens SIRIUS 3RP multifunction timer relay is the standard timing relay for industrial control panels in Saudi Arabia, replacing single-function mechanical timing relays with a single programmable device covering on-delay, off-delay, flasher, star-delta switching, single-shot, and interval timing functions selectable by front-panel rotary switch. The wide time range from 0.05 seconds to 100 hours in five selectable ranges and the DIN 43880 standard front panel width of 17.5 mm or 22.5 mm allow the 3RP to fit into standard control panels without dimensional adaptation.
The 3RP's multifunction capability reduces the variety of timing relay stock that panel builders and maintenance teams need to carry — a single 3RP with appropriate function and range settings replaces dedicated on-delay, off-delay, flasher, and star-delta timing relays. This simplification is particularly valuable for Saudi industrial panel builders and maintenance companies that service diverse equipment across multiple industries, where stocking many single-function timers creates parts management complexity.
In Saudi Arabia, the 3RP is the standard timer relay in motor starter panels for star-delta starting timing, pump alternation timers, alarm delay relays, and sequential process timing in HVAC, water treatment, and industrial process control panels. The 24 V DC and 12–240 V AC/DC supply voltage variants cover both PLC output-powered and direct line-powered timer applications.
Razz Middle East stocks SIRIUS 3RP timer relays in all function and voltage variants for immediate delivery throughout Saudi Arabia.

Key Features & Benefits
- Six timing functions selectable by front-panel rotary switch replace six separate single-function timing relays with a single stocked device, reducing panel parts variety for Saudi panel builders.
- Time range from 0.05 seconds to 100 hours in five selectable ranges covers star-delta switching (3–5 s), process delays (1–30 s), and long-interval monitoring functions.
- Wide supply voltage range 12–240 V AC/DC on the universal variant enables the same relay in 24 V DC PLC panels and 220 V AC control panels without separate model selection.
- Two changeover output contacts rated 8 A, 250 V AC provide sufficient loading for standard 4 kW contactor coils and solenoid valves without additional interface relays.
- DIN 43880 17.5 mm width fits standard IEC control panel cutouts, enabling drop-in replacement of competitor timing relays without panel modification.
- LED timing run indication provides visual confirmation of timing cycle progress during commissioning and fault-finding in motor starter panels.
- Internal potential-free supply voltage input enables the 3RP to be powered from the same auxiliary supply as the control circuit it sequences, simplifying panel wiring.
Industrial Applications in Saudi Arabia
- Star-delta motor starter timing relay at 3–8 second transition delay in Saudi industrial motor starter panels, replacing dedicated star-delta timing relays.
- Sequential pump starting delay timers in NWC and SWCC pump station panels, preventing simultaneous starting current surges during automatic start sequences.
- HVAC system startup sequencing timers controlling the start sequence of chillers, condenser water pumps, cooling tower fans, and AHU supply fans.
- Alarm delay relays for process instrument alarms in Saudi petrochemical facilities, adding a delay to prevent nuisance alarms from transient process disturbances.
- Alternating duty timers for dual-pump and dual-fan standby systems, automatically switching duty and standby equipment at timed intervals.
- Sump pump run-on timers at car park drainage systems in Saudi commercial buildings, maintaining pump operation for a set period after water level drops.
- Conveyor belt coast-down timers in industrial processing facilities, providing delayed stop signal to allow the belt to coast before applying a mechanical brake.
