T29-7721-1 is a single-pole hydraulic-magnetic circuit protector from the SNAPAK® series manufactured by Airpax, combining power switching, fuse functionality, and circuit protection in one integrated package. The device features a toggle paddle handle actuator available in six color options (blue, white, red, green, yellow, or black) with a 15° operating angle and snap-in front mounting design. Key technical specifications include a panel cutout diameter of 0.500 inches (12.7 mm) and mounting dimensions with tolerances of ±0.005 inches (0.13 mm) for precision panel installation. The single-pole configuration with one line connection simplifies assembly and reduces inventory requirements compared to traditional three-component solutions. This circuit protector is engineered for reliable operation in industrial and OEM applications where compact, integrated power switching and protection are required.
