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

Dependable DC Overcurrent Protection with Del City Hi-Amp 3/8" Stud Circuit Breakers

Del City’s hi-amp 3/8" stud auto reset circuit breakers provide dependable and automatic overcurrent protection for DC applications. Known as Type I Circuit Breakers, they feature an internal composite alloy material that deflects to separate the contacts during an overcurrent condition, automatically returning to the run mode once the breaker cools. This cycling operation continues until the overcurrent source is resolved, ensuring consistent protection. Designed for flat surface mounting, these circuit breakers are ideal for primary feeder circuits in trucks, buses, RVs, marine systems, battery chargers, and welding equipment.

Built to withstand harsh conditions, these circuit breakers are splash and dustproof to IP67 standards and meet SAE J1625, J1171, and UL1500 ignition protection requirements. Rated for up to 32V DC, they are constructed with a thermal plastic housing (UL rated 94V0) and include protective stud insulators for added safety. Featuring a 3/8" stud size with 16 threads per inch and a torque rating of 150 in-lb (17Nm) max, they provide secure and reliable connections. With an operating temperature range of -32°C to 82°C (-25°F to 180°F) and storage capacity from -34°C to 149°C (-30°F to 300°F), Del City’s 3/8" stud auto reset circuit breakers deliver exceptional performance across various environments.
