Monitoring Relays for Generators and ATS Systems
How phase-sequence, voltage/frequency and temperature monitoring relays let an ATS safely transfer a load onto a standby generator and back.
The TPSAUX33 is a Schneider Electric TransferPacT auxiliary contact module that clips on beside the transfer switch and signals when the switch is mechanically in the off position, through a 2 NO + 2 NC contact set rated 2 A at 250 V AC, wired with 0.75-2.5 mm squared cable on a PZ2 screwdriver terminal.
Fit the TPSAUX33 where a remote indicator or interlock needs to know the switch sits in the off position specifically, as distinct from the source I/source II signal the TPSAUX32 provides.
