المميزات والفوائد
- Adjustable thermal setting range of 36 - 45 A with temperature-compensated bimetals lets one device protect a band of motor full-load currents, cutting spares inventory at Saudi maintenance stores. Razz Middle East holds genuine stock in Dammam and Riyadh for fast Kingdom-wide despatch.
- Differential phase-loss (single-phasing) detection trips rapidly on a lost phase, preventing the winding burnouts that commonly follow supply faults on the Kingdom's long rural distribution feeders. Supporting the reliability standards demanded by Saudi oil, gas, water and petrochemical operators.
- Direct-mount S3 design clips onto companion 3RT2045-2047 contactors to form a self-contained starter with no inter-device wiring, speeding MCC assembly in Dammam and Riyadh panel shops. A specification advantage that EPC contractors value on Vision 2030 industrial and infrastructure projects.
- Selectable manual or automatic reset plus integrated NO + NC auxiliary contacts give flexible signalling and control wiring for both local panels and PLC-supervised motor control systems. Helping maintenance teams across the Eastern Province minimise unplanned downtime on critical drives.
- Trip class 10 characteristic matched to normal-starting motors, with a built-in test function supporting routine commissioning and preventive-maintenance checks on critical drives. And simplifying spares standardisation across large multi-site Siemens installations in Saudi Arabia.
- Certified to IEC 60947-4-1 with CE and UL approvals and rated -25 °C to +60 °C, meeting EPC specification requirements on ARAMCO, SABIC and NEOM motor protection schemes. Razz Middle East holds genuine stock in Dammam and Riyadh for fast Kingdom-wide despatch.
التطبيقات الصناعية
- Thermal protection of pump motors at NWC and SWCC water and desalination plants, where the 3RU2146-4HB0's phase-loss sensitivity guards costly submersible and booster pump windings across Jubail, Yanbu and the Eastern Province.
- Motor branch-circuit protection inside SABIC, Sadara and Sipchem petrochemical motor control centres, where the direct-mount S3 design enables compact, standardised starter buckets. Backed by local stock in Dammam and Riyadh and KSA-wide delivery to every industrial zone.
- Conveyor, fan and crusher motor protection at MAADEN mining and Saudi cement operations, where adjustable trip settings accommodate varied motor sizes on a common spares platform. Where reliable, type-tested Siemens equipment underpins plant availability and personnel safety.
- Utility and auxiliary motor protection in ARAMCO gas plants and refineries, where reliable overload and single-phasing detection underpins plant availability and personnel safety. Supported by Razz Middle East's technical selection and cross-referencing service for Saudi customers.
- Retrofit and replacement of ageing overload relays in existing Siemens starters Kingdom-wide, supplied as genuine factory-sealed units by Razz Middle East with four-hour RFQ response. Meeting the approved-vendor and traceability requirements of the Kingdom's major operators.
