Commercial thermal circuit breaker
Surface mounted
Thicker stud terminals to provide higher torque connections
Choice of 1/4" or 3/8" terminal studs
Stronger housing material for increased robustness
Ability to accomodate heavy gauge wire lugs across terminal studs
Meets SAE J553 and J1625 circuit breaker standards for surface vehicles
Meets SAE J1428 and J1171 marine circuit breaker standards
Meets 5000 amps @ 12 VDC for interrupt capacity per ABYC E-11 AC and DC electrical systems on boats

Based on proven Klixon technology, the F-series surface–mounted circuit breakers provide a 5,000 amp interrupt capability that exceeds industry performance standards. A 3/8–inch terminal option makes the F-series ideally suited for robust marine and heavy truck markets. This line of circuit breakers is also available for use in off–road equipment, electric vehicles and industrial applications.

Terminal studs are available in the 3/8–inch option to allow higher torque connections and provide wider spacing for heavy gauge wire lugs.
