Del City Hi-Amp 1/4" Stud Auto Reset Circuit Breakers: Reliable and Versatile for DC Applications

Del City’s hi-amp 1/4" stud auto reset circuit breakers provide dependable protection for DC applications, making them an excellent choice for a variety of uses, including primary feeder circuits in trucks, buses, RVs, marine systems, battery chargers, and welding equipment. Referred to as Type I Circuit Breakers, these breakers feature an internal composite alloy material that deflects to separate the contacts during an overcurrent condition. Once the breaker cools, it automatically returns to the run mode, continuously cycling until the overcurrent source is corrected or removed. Designed for flat surface mounting, they offer both reliability and ease of installation.

Built to withstand challenging environments, 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, they are encased in a durable thermal plastic housing (UL rated 94V0) and include protective stud insulators for added safety. With a 1/4" stud size featuring 28 threads per inch and a torque rating of 100 in-lb (11.3Nm) max, these breakers are engineered for secure and robust connections. Operating effectively in temperatures ranging from -32°C to 82°C (-25°F to 180°F) and suitable for storage between -34°C and 149°C (-30°F to 300°F), these breakers deliver consistent performance in diverse conditions.
