FAQs
Install as a four-pole device with screw terminals requiring 0.8 N·m tightening torque. Ensure front IP20 protection is maintained and note that the handle and shaft are not included, so plan for compatible mounting hardware or accessories. Mechanical drawings OT16-40FT4N1.igs are available for reference.
Rated main circuit voltage is up to 750 V with a rated operational current of 16 A (AC-22A). It supports voltages from 380–415 V and up to 690 V in AC-22A configurations, with compatible AC-23A ratings at lower currents. It achieves 0.3 W power loss per pole under rated conditions.
It complies with IEC 60947-3, UL 508, and CSA C22.2 No. 14. A CE Declaration of Conformity is available for compliance, and RoHS/CMRT declarations are provided to support material and environmental compliance.
Ideal for distribution panels, motor control centers, and machine feeders where reliable isolation and safe maintenance are required. Its four-pole configuration, IP20 protection, and 16 A current rating align with common industrial control and protection schemes in 380–690 V systems.
It offers up to 20000 mechanical cycles, enabling longer intervals between replacements in high-switching environments. Wiring remains secure due to screw terminals, and standard maintenance practices should verify torque and insulation integrity. RoHS/CMRT and environmental declarations support ongoing compliance during lifecycle management.
