ABB 1SFL587074R8611 Block Contactor - UL Listed

The ABB 1SFL587074R8611 Block Contactor combines a compact 3P footprint with three NO main contacts plus one NO and one NC auxiliary contact, enabling streamlined wiring and reliable motor control in rugged environments. This feature translates to a measurable business impact: smaller panel footprints, reduced cabling complexity, and simplified maintenance in high‑demand applications such as conveyors and pumps. The coil operates at 400…415 V for 50 Hz and 415…440 V for 60 Hz, delivering flexible control across regional power systems and enabling quicker commissioning with standard voltage rails. Rated Operational Current AC‑3 reaches up to 305 A across multiple voltages, while Rated Breaking Capacity AC‑3 and Making Capacity AC‑3 (8 x Ie and 10 x Ie) ensure safe, predictable switching during startup and load changes. With a 690 V insulation voltage and 8 kV impulse withstand, the device meets demanding safety standards and supports long service life in industrial environments. Mechanical durability of 5 million cycles and a maximum switching frequency of 300 cycles per hour reduce replacement intervals and maintenance costs. The unit uses bar terminals for the main circuit and offers available CAD drawings and documentation to accelerate installation and system integration. Product dimensions (140 mm width, 180 mm depth, 225 mm height) and a weight of 4.7 kg strike a balance between ruggedness and space efficiency, while IP40 protection and RoHS/REACH compliance reassure operators handling in controlled environments. In practice, this means faster project timelines, lower total cost of ownership, and robust compliance when paired with standard motor protection relays and control strategies.
