PTLC - Upgradeable Manual Transfer Switch Series
Upgradeable
ASCO manual transfer switches offer the flexibility to easily change your panel's
capabilities, without replacing the PTLC or rewiring your installation. Initially,
you may lower site costs by purchasing a PTLC with an ASCO UL 1008 Listed manual
transfer switch. An exterior handle allows power to be easily redirected from
its normal or utility source to an auxiliary power source.
As site needs change, or if you desire to save site visits to transfer load
sources, upgrade to an automatic transfer switch. When the upgrade is performed
in the field by ASCO-certified technicians, the factory warranty on the complete
panel is extended at no cost. The upgrade is accomplished with a phone call
to 1.800.800.ASCO (1.800.800.2726).
