FAQs
The 1SBL371074R7500 uses screw terminals and a compact 82x110x108 mm footprint, designed for standard control cabinets. It supports 3-pole configurations with IP20 protection, making it compatible with typical panel layouts and DIN-rail or surface-mounted enclosures when mounted side-by-side with add-on auxiliary blocks as needed.
For AC-1 operation, Ie is 95 A at 220/240 V, increasing to 115 A at 690 V (40 °C) and 80 A at 690 V (70 °C). For AC-3, Ie ranges to 65 A at 415–440 V, and 43 A at 690 V (55 °C). Pe values follow suit: 37 kW at 415–690 V, 30 kW at 380/400 V, and 18.5 kW at 220/230/240 V.
Yes. With 3 NO main contacts, 690 V insulation, and a robust mechanical design, it handles regular AC-3 motor switching and offers predictable inrush handling. The rated short-time withstand current (Icw) supports short transients, making it a reliable choice for conveyors, pumps, and fans in continuous or frequent cycling applications.
The product carries CE and UL/CSA certifications, plus CB and CCC attestations, enabling compliance in Europe, North America, and China. RoHS, REACH, and WEEE declarations further support lifecycle and environmental compliance across global supply chains.
With screw terminals and IP20 protection, maintenance is straightforward and field serviceable. The compact footprint reduces cabinet space, while low coil power losses (6.5 W AC-1, 1.5 W AC-3 per pole) lower energy consumption. Global certifications and modular accessories enable faster commissioning, lower wiring costs, and shorter time-to-market for multi-region deployments.
