FAQs
When installing the OT160E22C, ensure base mounting on a stable chassis and secure screw terminals with a tightening torque of 15-22 N·m. Remember the handle and shaft are sold separately, so select compatible components. Verify the 4P configuration and sign off on IP20 protection for indoor panel use to maintain safe operation.
The device is rated for 160 A across 380-415 V, 500 V, and 690 V, with an AC-23A rating at the same current. This combination supports high-load motor control and power distribution tasks while maintaining reliable switching, reducing heating and voltage drop in demanding applications such as fans, pumps, and conveyors.
The OT160E22C carries CE conformity, RoHS and Reach declarations, plus a DNV certificate. It is also referenced in CMRT and related environmental declarations. These certifications help simplify audits, supplier qualification, and end-user compliance in automotive, energy, and process industries.
The fourth pole is positioned on the right and switches simultaneously with the other poles, enabling coordinated interlocking and safer de-energization sequences. This reduces the risk of partial energization during transfer or maintenance, which is especially important in multi-line feeders and critical load scenarios.
Maintenance benefits come from its modular design, base mounting, and screw terminals that simplify wiring checks. The requirement to source the handle and shaft separately allows tailored ergonomic solutions. With its high current rating, robust insulation, and documented specifications, the device minimizes downtime and supports long service life in demanding environments.
