90 Amp Auto Reset Hi-Amp Circuit Breaker with 1/4" Studs

A Hi-amp 1/4" stud auto reset circuit breaker designed to be mounted on any flat surface application, and is commonly referred to as type 1 circuit breakers. This hi-amp breaker will operate/cycle continuously during an overcurrent condition in DC applications. It is 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. The auto reset circuit breakers operation will continue to recycle until the source of the overcurrent is removed or corrected. This circuit breaker is typically used in primary feeder circuits in trucks, buses, RVs and marine applications. However, it can also used in battery chargers and welding equipment.
