ABB 1SFL637001R7111 Block Contactor - 1000 V Insulation for industrial processes
Part Number: 1SFL637001R7111
Quick Summary
ABB 1SFL637001R7111 Block Contactor is a high-capacity switch designed to reliably start and stop motors in heavy-duty automation lines. It combines AF750 platform technology with pre-mounted auxiliary contacts to simplify installation and reduce panel depth. A common challenge engineers face is maintaining stable control in networks with voltage fluctuations; this device supports a wide control voltage range of 250–500 V at 50/60 Hz and DC, helping prevent nuisance trips. It also includes surge protection and a compact block design, enabling easy expansion with add-on auxiliary blocks. With CE and UL/CSA, UKCA certifications and RoHS compliance, it meets global requirements while delivering energy-efficient operation. In practice, it lowers energy consumption, improves uptime, and simplifies spare-part strategy.
Product Information
Extended Description
1SFL637001R7111 ABB: The AF750-30-11-71 is a 3 pole - 1000 V IEC or 600 V UL contactor with pre-mounted auxiliary contacts and Main Circuit Bars, controlling motors up to 400 kW / 400 V AC (AC-3) or 600 hp / 480 V UL and switching power circuits up to 1050 A (AC-1) or 900 A UL general use. Thanks to the AF technology, the contactor has a wide control voltage range (250-500 V 50/60 Hz and DC), managing large control voltage variations, reducing panel energy consumptions and ensuring distinct operations in unstable networks. Furthermore, surge protection is built-in, offering a compact solution. AF contactors have a block type design, can be easily extended with add-on auxiliary contact blocks and an additional wide range of accessories.

FAQs
The unit uses main circuit bars rated at 52 mm² and supports rigid Al-Cu cables up to 300 mm². Mounting torque for mains is 45 N·m, and coil terminals are IP20 protected. Use the 1SFC380023-en manual for step-by-step assembly and ensure proper auxiliary contact blocks are added if required.
Coil operating limits are 0.85 x Uc to 1.1 x Uc with θ ≤ 70 °C. Rated control circuit voltage is 250–500 V for both 50 Hz and 60 Hz, with DC operation also specified in the data.
Designed for motor protection and control in AC-3 applications, it supports motors up to 400 kW (AC-3) and 750 A ratings in various voltages. It features pre-mounted auxiliary contacts for signaling, and its compact block design supports scalable panel layouts.
The device carries CE and UL/CSA certifications, UKCA labeling, RoHS compliance, and related declarations. These certifications support global deployment in industrial facilities and OEM projects.
With mechanical durability rated at 3 million cycles and built-in surge protection, maintenance intervals are extended and downtime decreases. The wide voltage tolerance reduces energy waste, and easier expansion with add-on contact blocks lowers total cost of ownership for motor-driven lines.
