Product details

Integration Notes

The 1SFA894008R7020: Main circuit terminals are bars with an 8.5 mm hole diameter — expect busbar or ring-lug connections, not cage clamps. Control circuit terminals accept 1 x 2.5 mm² rigid and require 0.5 N·m tightening torque. Ambient operating range is 0 to +50 °C. Communication is via a standard FieldBusPlug — no separate fieldbus module needed for basic connectivity. Signal relays are provided for run, fault, bypass, and overload status; a red LED indicates fault, yellow indicates protection.

Frequently asked questions

What is the ramp time range for 1SFA894008R7020?
