FAQs
The ABB 1SBL411074R7500 is a three-pole block contactor designed to control 3-phase motors and power circuits up to 690 V AC. It supports mains up to 690 V and a rated current Ie of up to 125 A at 690 V, making it suitable for large fans, pumps, conveyors and other heavy-load applications.
This block contactor carries CE, UL/CSA, CCC, and CQC certifications. These approvals facilitate global procurement, ease compliance with regional electrical codes, and reduce qualification time in multinational or multi-site projects, while signaling adherence to safety and performance standards expected in industrial environments.
The device measures 82 mm in width, 110 mm in depth, and 108 mm in height, with a net weight of 1.05 kg. These compact dimensions support dense panel layouts and easier retrofits, enabling efficient use of enclosure space during installation or replacement.
The 1SBL411074R7500 is designed for typical AC-1 and AC-3 switching with a maximum switching frequency of 600 cycles per hour. It supports optional auxiliary contact blocks for signaling and interlocks, and is compatible with external thermal overload relays within AX50-80A configurations to enhance protection for motors with high inrush or thermal sensitivity.
Power loss is 7 W per pole for AC-1 operation and 2 W per pole for AC-3 operation, contributing to moderate energy use and cooler running in steady-state conditions. Maintenance benefits include robust mechanical design, standard screw terminals, and compatibility with common accessories, which simplify servicing and spare-part sourcing.
