Part of the classic F-frame series, this 100A single-pole molded case circuit breaker delivers 25kAIC interrupting capacity at 277VAC. It installs into older Square D commercial panelboards and switchboards requiring bolt-on connections. Featuring fixed long-time and instantaneous trip functions, the unit is HACR rated for heating and cooling equipment. It serves as an exact match for existing installations and can be substituted with the FHL16100 model if higher ratings are needed.
