GTE Sylvania QFP24-150 Two Pole Circuit Breaker

The GTE Sylvania QFP24-150 is a 2-pole circuit breaker designed for 240-volt electrical systems, rated at 150 amperes to protect high-current branch circuits in GTE Sylvania Zinsco‑style panels. This breaker interrupts both hot legs of a 240V circuit when it trips, providing simultaneous disconnection of the two conductors for safety and code compliance. It is part of the QFP24 family, and the 150-amp designation is often cataloged as QFP24-150; some listings refer to the same unit as QFP2150, reflecting the amp rating within the QFP24 designation. As a legacy GTE Sylvania/Zinsco component, it belongs to the line of breakers used in panels that specify QFP‑series replacements and interchangeability within that panel ecosystem. Suitable for installations where a 150A protection level on a 240V circuit is required, this device is commonly found in older electrical panels designed for Sylvania/GTE Zinsco breakers. When replacing or upgrading, verify that the panel label lists QFP24-type breakers as acceptable and that the 150A rating matches the circuit’s protection needs.
