FAQs
This device is designed as a 3P switch-disconnector with screw terminals and a 0.8 N·m tightening torque, suitable for main circuit isolation in control cabinets and automation panels. It fits OT16-40 family configurations and supports integration with standard IEC 60947-3 rated systems. For retrofit projects, ensure the panel offers compatible mounting spacing and terminal blocks to maintain IP20 protection and a secure termination.
Key ratings include a Rated Operational Current (Ie) of 16 A for AC-22A and AC-23A across a main circuit voltage up to 750 V. It features a Rated Insulation Voltage of 750 V and a Rated Short-Time Withstand Current (Icw) of 0.5 kA for 1 s, with a Rated Short-Circuit Making Capacity (Icm) of 0.71 kA at 690 V. These figures support reliable performance in typical 3P industrial applications.
Yes. The device is specified for 380–415 V applications with an Ie of 16 A and an insulation rating up to 750 V. Its 3P configuration and 0.8 N·m tightening torque make it well-suited for compact control cabinet installations, providing dependable isolation without compromising safety or accessibility in medium-voltage distribution panels.
ABB 1SCA126073R1001 complies with IEC 60947-3, UL 508, and CSA C22.2 No. 14 standards. It carries front IP20 protection, environmental declarations (PEI OT16-40, EPD), and RoHS/CMRT commitments. This mix of certifications helps simplify procurement, regulatory compliance, and sustainability reporting for regulated industries.
The 20,000 mechanical cycle durability reduces replacement frequency, while low per-pole power loss (0.3 W) minimizes cooling requirements and energy waste. The screw-terminal design simplifies installation and servicing, shortening downtime during maintenance. Together, these factors can lower total cost of ownership and improve return on investment for control cabinets and machine automation projects.
