Allen-Bradley 160-BA03NSF1 Safety Relay Module

The Allen-Bradley 160-BA03NSF1 is a 1 HP (0.75 kW) AC speed controller in the 160 SSC family that provides precise motor speed control for 3‑phase loads on 380–460 VAC systems. It accepts 380–460 VAC input on a three‑phase supply and delivers up to 0.75 kW to a motor with a typical current draw of about 2.3 A, housed in an IP20 enclosure for basic indoor protection. The drive supports local panel access and, with optional modules, remote configuration, and it can be connected to Rockwell PLCs and SCADA systems through DeviceNet using the 160‑DN1 module. For onboard setup without an external programmer, an optional keypad module (P1) is available, and the model is commonly used to control conveyors, fans, and pumps in industrial automation.
