Three-pole switch-disconnector with a 750 V rating and 16 A Ie enables reliable main-circuit isolation while keeping the panel footprint compact. This translates to faster commissioning and reduced wiring complexity in machine control and power-distribution applications. Mechanical durability of 20000 cycles and a tight 0.8 N·m tightening torque ensure long service life and repeatable connections in demanding environments, minimizing maintenance windows and replacement costs in production lines and packaging equipment. Cable cross-section range of Cu 0.75 … 10 mm² and screw-terminal connections support flexible wiring and straightforward field assembly, improving installer efficiency and reducing retrofit risk. Rated Operational Current AC-22A and AC-23A at up to 750 V across multiple voltages ensures compatibility with diverse loads—from low-power controls to higher-power starters—while remaining compliant with IEC 60947-3, UL 508, and CSA standards to minimize design risk. Documentation and environmental metadata simplify procurement and compliance, with data sheets, mechanical drawings, EPD/CMRT declarations, and RoHS/REACH statements that accelerate audits and sustainable sourcing for panel builders and integrators.

FAQs
The 1SCA126072R1001 uses standard screw-terminals compatible with 0.75–10 mm² Cu conductors and a tightening torque of 0.8 N·m, facilitating direct replacement in 3P panels. Its 750 V main-circuit rating and IP20 front protection support safe operation in common industrial control cabinets, while the 3P arrangement aligns with standard motor control and distribution setups.
For AC-22A, the device supports up to 16 A across 380–415 V, 500 V, and 690 V ranges; for AC-23A, it also handles 16 A with similar voltage bands but lower current in some configurations. Rated operational voltage is 750 V, with Icm up to 0.71 kA and Icw up to 0.5 kA for 1 s, ensuring safe interruption of typical industrial loads.
Yes. The OT16-40F3U/B50 family is designed for main-circuit isolation in control panels, offering 3P switching, 16 A rated current, 750 V capability, and 3P configuration.
