Eaton ACK-250 Time Delay Stud Mount Fuse 250A 32V

Product Description

The EATON ACK-250 is a time delay, stud mount fuse rated for 32 volts DC service. Designed for high-current DC circuit protection, this fuse provides reliable overcurrent interruption in automotive, marine, heavy equipment, and industrial DC power systems. The stud mount configuration allows direct busbar or terminal block installation, making it a practical choice for panel builders and service technicians working with large-format DC distribution. At 250 amps, it handles substantial continuous loads while the time delay characteristic tolerates inrush currents without nuisance blowing.

This fuse is suited for residential solar storage systems, commercial vehicle electrical panels, marine DC distribution boards, and industrial battery-backed equipment where a stud mount format is required. The 32V DC voltage rating aligns with 12V, 24V, and 32V nominal battery systems commonly found in heavy-duty transport, off-grid power, and mobile equipment applications. Installation is performed by licensed electricians or qualified DC systems technicians familiar with high-amperage DC wiring practices.

Key Features

• 250-amp continuous current rating for high-load DC circuits
• 32V DC voltage rating compatible with 12V, 24V, and 32V battery systems
• Time delay design tolerates motor start and capacitor inrush currents
• Stud mount termination for direct busbar or lug connection
• Compact form factor at 0.288 pounds for tight panel installations

Compatibility

Designed as an OEM-style replacement for stud mount time delay fuses used in 32V DC high-current distribution panels and protection circuits.

Installation Notes

Installation should be performed by a qualified electrician or DC systems technician following applicable NEC guidelines for DC overcurrent protection. Always disconnect and isolate the battery source before handling or replacing this fuse. Verify that the replacement fuse amperage and voltage rating match the original circuit design before re-energizing. Do not substitute a non-time-delay fuse in applications where inrush current tolerance is required.
