FAQs
The device uses base mounting with screw terminals, rated at 6 N·m tightening torque. It supports 10–70 mm² conductors and offers top input or bottom output configurations for flexible wiring. Ensure the panel provides adequate space for a 193 mm wide, 100 mm high unit and follow the IEC 60947-1 torque and safety clearances during assembly.
AC-21A ratings indicate non-photoelectric, steady-state AC load switches at specified voltages; this unit provides 100 A at 380–415 V, 500 V, or 690 V, with AC-23A up to 80 A at 380–415 V, 60 A at 500 V, and 40 A at 690 V. The 37 kW PE rating applies at those voltages, ensuring it handles typical industrial motor and load profiles safely.
Yes. The OT100F4C design with open transition supports reliable source transfer with controlled arcing, optimized for front-operated applications in panel assemblies.
