Overview
The ABB THHQL2125 is a 25 A, 2-pole Q-Line plug-in circuit breaker for 120/240 V AC circuits in compatible ABB and legacy GE load centers and lighting panels. Its fixed, non-interchangeable thermal-magnetic LI trip provides overload and short-circuit protection with a 22 kA interrupting rating.
Key Features
-
Protection: Fixed thermal-magnetic LI protection with a common trip mechanism for two-pole circuits.
-
Installation: Q-Line plug-in mounting with box-type terminals accepting 14-8 AWG copper or 12-8 AWG aluminum conductors.
-
Compatibility: Designed for compatible ABB and legacy GE Q-Line load centers and lighting panels; suitable for reverse feed where permitted by the equipment instructions.
-
Performance: Rated 25 A at 120/240 V AC with 22 kAIC interrupting capacity, HACR marking, and UL File E11592.
