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 TPSAUX44 is a Schneider Electric TransferPacT auxiliary contact module that clips inside the front cover of a frame 250 A or frame 630 A switch and signals the off position through a 2 NO + 2 NC contact set, wired on spring terminals and rated for a 100 mA minimum load at 24 V DC.
Fit the TPSAUX44 where the off position needs its own hard-wired contact on a TA25/TR25 or TA63/TR63 frame; combine it with the TPSAUX43 when both source position and off position must be signalled.
