ASCO service Entrance Power Transfer Switch rated 2000 Amperes, shown in a Type 1 indoor enclosure.
The ASCO Service Entrance Power Transfer Switch combines automatic power switching with a circuit breaker as a disconnect and overcurrent protective device on the utility source. The power transfer switch meets all National Electrical Code requirements for installation at a facility's main utility service entrance.

Service entrance rated transfer switches generally are installed at facilities that have a single utility feed and a single emergency power source. A circuit breaker serves as the utility disconnect. Neutral disconnect and main bonding jumper bus links are both provided.

The ASCO 7000SE Service Entrance Automatic Transfer Switch uses the same reliable transfer switching mechanism, and controller as the 7000 Series product platform.

  • Available from 150 to 4000 amperes.
  • ASCO 7000 Series Power Transfer Switch, UL 1008 listed.

  • Ground and neutral bus, all silver-plated copper
  • Solderless screw type terminals for External Power Connections.
