Allen-Bradley 509-FOB-A2N Brand Introduction
Allen-Bradley 509-FOB-A2N is 509 series NEMA Size 5 full voltage non-reversing motor starter developed by Rockwell Automation for three-phase heavy-duty motor on-off discrete control. It specializes in connecting and cutting off power supply for large high-power induction motors, serving as open-type direct-on-line contactor assembly equipped with E1 Plus solid-state overload relay for industrial motor control cabinets. Motor Starter is the core unit of Allen-Bradley 509-FOB-A2N. Motor Starter adopts open frame panel mounting structure for standard heavy-duty motor control enclosures. Motor Starter integrates E1 Plus solid-state overload relay for motor overcurrent and overload protection. Motor Starter realizes start and stop control of field high-power motors according to control circuit logic. Allen-Bradley 509-FOB-A2N provides stable Drive for workshop field heavy-duty high-power motor load control. Drive supports max 600VAC operating voltage and 270A continuous rated current. Drive has reliable solid-state thermal overload protection function for motor overload and overheat protection. Drive features robust heavy-duty silver alloy contact for frequent large-current start-stop operation. Allen-Bradley 509-FOB-A2N features reliable Transmission for control circuit and field motor devices. Transmission communicates via control wiring loop. Transmission is fully compatible with low voltage motor control systems and auxiliary control components. Transmission delivers fast switching signals to field heavy-duty high-power motor loads. Allen-Bradley 509-FOB-A2N is widely used in large industrial fan, heavy conveyor, pump unit and legacy heavy motor control system renovation. With mature Rockwell low voltage starter technology, this motor starter works within temperature range 0~40℃ and has strong anti-vibration performance. It provides full lifecycle technical support including wiring, commissioning and after-sales maintenance, serving global users as a trusted NEMA Size5 full voltage motor starter solution.
