Siemens 3RW3014-1BB04 Soft starter

Siemens SIRIUS is the modular switching and motor-control platform behind most IEC control panels built today: contactors, contactor relays, overload relays, motor starter protectors, soft starters and solid-state switching devices across the 3RT, 3RH, 3RA, 3RV, 3RW, 3RB, 3RU, 3RF and 3RN families. Razz Middle East supplies the full SIRIUS range throughout Saudi Arabia, sourced to order and delivered duty-paid.

About SIRIUS Switching & Motor Control

SIRIUS is Siemens' IEC low-voltage switching and motor-control family, designed as a coordinated system rather than a catalogue of unrelated parts. The 3RT2 contactor is the core building block, with 3RH2 contactor relays for control-circuit logic, 3RU2 thermal and 3RB3 solid-state overload relays for motor protection, and 3RV2 motor starter protectors combining short-circuit and overload functions in one device. 3RA2 assemblies pre-combine these into direct-on-line and reversing starters, while 3RA6 compact starters integrate the whole function into a single narrow unit. For gentler starting and stopping, 3RW3 and 3RW4 soft starters ramp voltage or torque to limit inrush current and mechanical shock. 3RF2 solid-state relays and contactors handle high switching frequencies where mechanical contacts would wear out; 3RN2 thermistor relays protect motors by monitoring winding temperature directly; 3RQ3 interface relays adapt controller outputs to power circuits. The devices share common accessory ranges, including auxiliary contact blocks, surge suppressors, link modules and mounting accessories, so a panel builder can standardise one accessory kit across an entire assembly. Siemens also publishes Type 1 and Type 2 coordination tables defining which device combinations have been verified together.

SIRIUS Switching & Motor Control in Saudi Arabia

Saudi panel builders assembling motor control centres and distribution boards for SEC-approved projects specify SIRIUS heavily, because Siemens coordination data is accepted by consultants and the range covers the whole starter chain from one manufacturer. Typical destinations are pump and blower starters for SWCC and NWC water and desalination plants, conveyor and crusher drives at Ma'aden sites, utility and package-plant motor control for Aramco and SABIC contractors in Jubail and Yanbu, and building-services starters for MEP contractors on NEOM, the Red Sea Project and Riyadh Metro packages. Maintenance teams in Dammam and Khobar order replacement contactors and overload relays against existing panel schedules, where the article number has to match exactly. All electrical goods entering the Kingdom require SASO conformity and SABER registration, and we handle import and clearance so the consignment arrives compliant and duty-paid.

Ordering and lead time

Order by full Siemens article number, the complete MLFB rather than a shortened family reference, because a single digit separates coil voltages, contact configurations and terminal types. Before you send the RFQ, confirm the following: is the coil voltage AC or DC, and at what value? How many auxiliary contacts, NO and NC, does the schematic call for? Screw or spring-loaded terminals? For protection devices, which trip class or setting range applies, and for soft starters, which control supply and bypass arrangement? Send your list and we respond within four hours. Goods are sourced to order from our supplier in Italy, with a typical lead time around three weeks, and delivered duty-paid to your site, with import, clearance and the 5% customs duty itemised separately.

Specifications are taken from the supplier's published catalogue data. Confirm against the current Siemens datasheet before ordering.
