The GE ABB THHQB32020 is a 3-Pole, High-Interrupting Capacity, Molded Case Circuit Breaker from the GE Q-Line series. The 'QB' signifies it is a Bolt-On style breaker, and the 'HHQ' indicates its high interrupting rating.
Features
-
High Interrupting Capacity (22 kA): The 'HHQ' designation means this breaker is suitable for locations with high available fault currents, providing enhanced protection compared to standard 10 kA breakers.
-
Common Trip: Features a common trip bar that ensures all three poles disconnect simultaneously when an overload or short circuit occurs on any single pole, protecting 3-phase equipment.
-
Bolt-On Design: The QB (Bolt-On) style provides a highly secure and reliable connection to the panel bus bar, which is often preferred in commercial and industrial settings over plug-in types.
-
Quick-Make/Quick-Break: Utilizes a mechanism that ensures contacts open and close rapidly, minimizing arcing and maximizing contact life.
-
Trip-Free Mechanism: The breaker trips under fault conditions even if the handle is manually held in the ON position, guaranteeing protection.
-
Suitable for Reverse Feed: Can be installed to receive power at the load side terminals, though a main breaker retainer kit may be required depending on the panel and application.
- HACR Rated: Suitable for use in Heating, Air Conditioning, and Refrigeration applications.
