Overview – WN3 ATS 1600/2000A 3 POLE 0306-5061-03
The Cummins WN3 ATS 1600/2000A 3 POLE 0306-5061-03 is a direct replacement used in Cummins generator and power-system positions as the automatic transfer switch moving the load between the utility and the generator, with no modification required at installation.
Parts Characteristics
An automatic transfer switch that senses a loss of the utility feed and moves the load to the generator, then returns it when the mains returns, so the site stays powered through the outage. It carries the switching and the interlock that the whole install depends on, so a true, correctly rated ATS keeps the transfer clean and the two sources from ever meeting.
Applicable Models & Applications
Used at Cummins generator and power-system positions specifying this WN3 ATS (1600/2000A, 3 pole). Match the frame size, the pole count and the control logic against your switchgear – transfer switches differ in how they sense and switch.
Maintenance & Replacement
Inspect the contacts for pitting and the mechanism for free travel at every service. A switch that has begun to stick transfers late, and the late transfer is what drops the load.
Confirm the control supply and the sensing are live on fit. A switch with a dead sense feed never trips, and the never is what leaves the site dark.
Exercise the switch on a schedule rather than waiting for a real outage. A transfer switch that sits unused seizes, and the seize is what fails the one time it is needed.
Keep the correct ATS for your genset on the shelf. It is load-critical, and a site dark on a failed switch is a building waiting on a large part.
