Merit Brass A3T110 Class T Fuse

Product Description

The MERIT BRASS A3T110 is a Class T fuse designed for high-interrupting-capacity overcurrent protection in electrical distribution systems. Class T fuses are compact, current-limiting devices rated for use in circuits requiring fast-acting, reliable fault protection. Licensed electricians and electrical contractors install Class T fuses in panelboards, switchboards, and motor control equipment where space-saving form factors and high short-circuit current ratings are required. The A3T110 is a recognized trade staple for applications demanding reliable overcurrent protection in a standardized Class T form factor.

Class T fuses are used in both commercial and industrial electrical systems. Typical installations include motor control centers, industrial machinery panels, and main distribution boards where compact fuse dimensions and high interrupting ratings are necessary. This fuse suits applications where the panel layout restricts the use of larger Class J or Class RK fuses. Electricians sourcing replacements or new installations will find the A3T110 fits standard Class T fuseholders.

Key Features

• Class T form factor provides compact dimensions relative to interrupting capacity
• Current-limiting design helps reduce let-through energy during fault conditions
• Standardized Class T rejection-style form prevents cross-installation with incompatible fuse classes
• Suitable for commercial and industrial electrical distribution applications

Compatibility

Designed as an OEM-style replacement or direct fit for standard Class T fuseholders rated for the A3T110 form factor.

Installation Notes

Installation must be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lock out the circuit before removing or installing any fuse. Use an insulated fuse puller rated for the voltage class of the circuit. Never replace a fuse with a unit of a higher ampere rating than the circuit is designed to carry.
