Mersen A6T150 Class T Fuse 150A 600V

Product Description

The MERSEN A6T150 is a Class T current-limiting fuse rated at 150 amps and 600 volts AC. Class T fuses are recognized for their compact form factor and high interrupting capacity, making them a standard choice in industrial and commercial electrical distribution panels, motor control centers, and switchboards where space is limited and fault-current protection is critical. Licensed electricians install this fuse as a branch-circuit or service-entrance protective device. The A6T150 provides fast-acting overcurrent protection that helps safeguard downstream equipment from the damaging effects of short-circuit current.

This fuse is suited for use in commercial and industrial electrical systems where Class T rejection-style fuseholders are installed. Typical applications include motor branch circuits, feeder circuits, and service-entrance equipment in facilities requiring high interrupting capacity protection. The compact dimensions of 1.380 inches by 1.380 inches by 3.440 inches allow installation in tight panel layouts. It ships as a single fuse per pack.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit completely before removing or installing any fuse. Verify the fuseholder is rated for Class T fuses and matches the voltage and ampere rating of the A6T150 before installation. Never install a fuse in a holder that shows signs of heat damage, corrosion, or mechanical wear.
