General Electric SGDA22AT0400 U Circuit Breaker

General Electric SGDA22AT0400 U is a two-pole circuit breaker rated for 400 amps at 240 volts. This GE device provides overcurrent protection for 2-pole circuits by disconnecting both hot legs when an electrical fault or overload occurs, helping to protect wiring and connected equipment. With a 400 A rating, it is intended for high-current circuits within commercial or industrial electrical installations that operate at 240 V. Two-pole operation ensures both hot conductors trip together, reducing the risk of shock or equipment damage on 240 V circuits. The U designation in the part number identifies this specific variant within the SGDA family. In typical setups, a 2P, 240 V circuit breaker like the SGDA22AT0400 U would be used to safeguard feeders, large branch circuits, or main distribution paths in appropriate panels. Ensure you select a breaker that matches the panel’s specifications and mounting style for safe, compliant operation.
