Siemens Sirius 3RT2 Contactor 25A 4kW AC-3

Siemens Sirius 3RT2 Contactor 25A 4kW — Standard Industrial Motor Contactor for Saudi Arabia

The Siemens Sirius 3RT2 contactor is the standard industrial motor contactor used across Saudi Arabia — found in motor control centers at Saudi Aramco pump stations, SABIC chemical plants, and SWCC desalination facilities. The 3RT2 series delivers 25A AC-3 rating suitable for 4kW motors at 400V, with proven reliability in the high-temperature, dusty environments of Dammam, Jubail, and Riyadh industrial zones.

Key Features for Saudi Applications

AC-3 Rating 25A / 4kW: Handles the majority of small to medium motor sizes — pumps, fans, compressors, and conveyors.

AC/DC Coil Options: Available with AC (50/60Hz) or DC coil — DC coils eliminate coil burnout from voltage sag during Saudi brownout conditions.

Spring-Type Terminals: Spring-loaded terminals provide vibration-resistant connection — critical for equipment mounted on vibrating structures in Jeddah port and Dammam industrial zones.

IEC 60947-4-1 Compliant: Full compliance with motor contactor standards required by Saudi Aramco SASO certification.

Applications in Saudi Arabia

Saudi Aramco Pump Stations: 3RT2 contactors control fire water pumps and injection pumps at Aramco upstream facilities.

SWCC Desalination Plants: 3RT2 drives seawater intake and transfer pumps across the Red Sea coast.
