    "description": "12VDC, 40A custom ATO-format auto-resetting (Type I) thermal circuit breaker in an orange anodized aluminum case; meets SAE J553. Designed to protect FRC robot actuator branch circuits. Two ATO/ATC blade terminals (power in / power out) make it a pass-through inline protection device. Auto-resetting Type I: a thermal element trips on sustained over-current and re-closes automatically after the element cools. Holds 100% of the 40A rating for >=1800 s; trips in 5-60 s at 200% rated current. Color-coded (orange = 40A) anodized aluminum case with stamped 12V / 40A ratings for easy identification. Sold as a 4-pack (REV-11-1863-PK4); each breaker is REV-11-1863.",
