Merit Brass A6T250 Class T Fuse 250A 600V

Product Description

The MERIT BRASS A6T250 is a Class T current-limiting fuse rated for 250 amps at 600 volts. Class T fuses are compact, high-interrupting-capacity devices used to protect electrical circuits, motors, and distribution equipment from overcurrent faults. Their fast-acting design limits let-through energy to safeguard downstream components. Licensed electricians and electrical contractors install this fuse type in commercial and industrial panels, disconnect switches, and equipment protection applications where UL Class T rejection sizing is required.

This fuse is suited for residential, commercial, and light industrial electrical systems where 600-volt, 250-amp overcurrent protection is needed. Class T fuses are commonly installed in fusible disconnect switches, motor circuit protectors, and service entrance equipment. Their compact form factor allows installation in space-constrained enclosures where larger fuse classes will not fit. The A6T250 is sold individually and ships in a single-unit pack.

Key Features

• 250-amp continuous current rating for heavy-duty circuit protection
• 600-volt rating suitable for standard commercial and industrial distribution voltages
• Class T form factor with rejection sizing to prevent misapplication
• Current-limiting design reduces let-through energy during fault events
• Compact dimensions allow installation in space-restricted enclosures

Compatibility

Designed as an OEM-style replacement for Class T fusible disconnect switches and overcurrent protection devices requiring a 250-amp, 600-volt Class T fuse.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit at the upstream disconnect before handling or replacing any fuse. Verify the replacement fuse amperage and voltage rating match the circuit requirements before installation. Do not substitute a different fuse class or a higher amperage rating in a Class T rejection holder.
