ASCO Series 300 Power transfer Load Center rated two pole, 400 amperes with optional transient voltage surge suppression on utility and generator sources.
Everything that is needed to protect sensitive loads from power outages and transients is in one package: World-class ASCO Series 300 Automatic Power Transfer Switch with microprocessor digital controller, versatile Square D Load Distribution Panel, and protective transient voltage surge suppression for normal and emergency operation.

ASCO Automatic Transfer Switches are the standard of the industry and represent the most advanced technology in transferring loads between two power sources.

Available in 200 or 400 amp rating, 120/240 VAC 60 Hz single phase, 3 wire or 120/208 VAC, 60 Hz three phase, 4 wire.

The PTLC includes a 42-position load distribution panel. Main circuit breakers provide over current protection and disconnect for convenient and safe serviceability. The shallow profile facilitates installation.

When power fails, the UL 1008 listed automatic transfer switch follows user-set time delays to start the generator, transfer the load to the generator, reconnect to utility power and shut down the generator after generator cool down.
