Mainline Power Protection

PTLC - Automatic Transfer Switch Series

PTLC - Automatic Transfer Switch SeriesThese integrated panels save valuable on-site service costs and ensure "always-on" power to mission- and revenue-critical electronics. With integrated surge protection, PTLC's protect sensitive downstream equipment from downtime caused by power outages and from damage caused by voltage variances, which are inherent in power delivery.

ASCO automatic transfer switchIntegrated load centers with an ASCO® automatic transfer switch automatically detect the loss of power on the utility or normal feed. Once normal power loss is detected, the switch automatically transfers the load to an emergency power source. The switch continues to monitor power and will revert to the primary source once power is reinstated and stabilized. With the Automatic Transfer Switch PTLC, power to critical equipment is insured without the need for on-site field service personnel to "make and break" the connection.
