Merit Brass A6T6 Class T Fuse 6 Amp 600V

Product Description

The MERIT BRASS A6T6 is a Class T fast-acting fuse rated at 6 amps and 600 volts, designed for use in high-fault-current electrical systems where compact, high-interrupting-capacity protection is required. Class T fuses deliver extremely fast clearing times, limiting let-through energy during fault conditions. This fuse is installed by licensed electricians in panelboards, disconnect switches, motor control centers, and industrial control equipment where NEC-compliant overcurrent protection is mandatory. Its small physical footprint relative to its voltage and interrupting rating makes it well suited for installations where space is constrained.

Class T fuses are commonly specified in residential, commercial, and light industrial electrical systems that require high interrupting capacity in a compact form factor. The A6T6 is appropriate for branch circuit and feeder protection in 600-volt AC systems. Electricians also use Class T fuses in combination motor controllers and fusible disconnects where fast-acting protection helps safeguard downstream equipment from sustained overcurrent damage.

Key Features

• Class T fast-acting design for high-interrupting-capacity overcurrent protection
• Rated 6 amps at 600 volts AC
• Compact dimensions suitable for space-limited enclosures
• Packaged 10 units per pack for efficient stocking and service calls
• Lightweight at 0.03 pounds per fuse for easy handling and installation

Compatibility

Designed as an OEM-style replacement Class T fuse for 600-volt fusible disconnect switches, motor control centers, and panelboards that accept Class T fuse holders.

Installation Notes

Installation must be performed by a licensed electrician in accordance with applicable NEC requirements for overcurrent protective devices. De-energize and lock out the circuit at the upstream overcurrent device before removing or installing any fuse. Use an insulated fuse puller rated for the voltage class when extracting Class T fuses from live-adjacent equipment. Verify that the replacement fuse ampere rating and voltage class match the original protective device specifications before restoring power.
