Del City Hi-Amp Surface Mount Circuit Breakers - 3/8" Stud Auto Reset

Del City hi-amp 3/8" stud auto reset circuit breakers are designed to be mounted on any flat surface application, and are commonly referred to as type 1 circuit breakers. These hi amp breakers will operate/cycle continuously during an overcurrent condition in DC applications. It's the internal composite alloy material which will deflect and separate the contacts when an over-current situation occurs and return to the run mode as it cools. Del City auto reset circuit breakers operation will continue to recycle until the source of the overcurrent is removed or corrected. These circuit breakers are typically used in primary feeder circuits in trucks, buses, RVs and marine applications. However, they can also be used in battery chargers and welding equipment.
