FAQs
This block contactor uses screw terminals for both main and control circuits, simplifying field wiring and maintenance. It supports add-on auxiliary contact blocks (NO/NC) for extended control logic and remote signaling without rearranging the main contactor base, making retrofit projects and new builds straightforward and time‑saving for technicians.
For AC‑3 at 690 V, Ie is 35 A and Pe is about 30 kW, while for AC‑1 at 690 V, Ie reaches 100 A (40 °C) or 70 A (70 °C). These ratings ensure reliable motor starting and running within typical pump and conveyor loads, with safe thermal margins under continuous duty.
Yes. With 3 NO main contacts, 1 NO and 1 NC auxiliary contact, and 690 V insulation, the ABB 1SBL351074R2611 supports three‑phase motor control up to several tens of kW. Its compact footprint and robust thermal performance make it well suited for conveyors, pumps, and processing lines in automation projects.
The product carries CE declarations and UL/CSA certification alongside RoHS compliance, CCC/CQC equivalents relevant to regional markets, and CE conformity documentation. This mix supports global installation in compliant panels and machines, reducing regulatory hurdles in multinational facilities.
Routine inspection of terminal connections, coil condition, and auxiliary contacts is advised. The device’s Ith 100 A and AC‑3 35 A at 690 V, plus low per‑pole power loss (5 W AC‑1, 1.3 W AC‑3), contribute to lower heat, fewer cooling requirements, and longer service intervals, delivering lower total cost of ownership and improved uptime.
