FAQs
Installation with AX50‑AX80 accessories is straightforward due to the block design and compatible add-on auxiliary contact blocks. Use screw terminals, tighten coil terminals to 1 N·m and main terminals to 4 N·m, mount per the 82 mm width, and ensure the device sits within its IP20/IP10 protection envelope. This minimizes wiring errors and speeds up panel commissioning.
AC‑1 ratings cover non‑switching motor loads such as resistive or lightly inductive circuits, while AC‑3 ratings apply to motor switching with starting currents and overloads. For this contactor, AC‑1 currents reach up to 115 A at 690 V, and AC‑3 currents reach up to 65 A at 415–690 V, with corresponding power ratings. These figures guide proper sizing for reliable motor control.
Yes, the ABB 1SBL371074R8411 is rated for 690 V insulation and main circuit operation. It provides IP20 protection for control terminals and IP10 for main terminals, along with a 6 kV impulse withstand on the auxiliary circuit. This combination supports safe use in typical industrial control cabinets and power distribution.
The product carries CE, UL/CSA, CCC, and CQC certifications, plus relevant DoCs. CE and UL/CSA facilitate compliance in Europe and North America, while CCC/CQC address Chinese market requirements. This broad certification footprint helps streamline procurement for multi-region projects and reduces the need for multiple variants.
With a maximum mechanical switching frequency of 3600 cycles per hour and a maximum electrical frequency of up to 600 cycles per hour (AC‑1/AC‑3), the device supports high-cycle operation. Coupled with low coil power loss (6.5 W AC‑1, 1.5 W AC‑3 per pole) and robust build, this yields lower energy costs, longer service intervals, and a favorable return on investment in demanding automation lines.
