Merit Brass A3T175 Class T Fuse

Product Description

The MERIT BRASS A3T175 is a Class T fuse designed for high-fault-current protection in electrical distribution systems. Class T fuses are current-limiting, fast-acting overcurrent protection devices rated for applications where space is limited and high interrupt capacity is required. The A3T175 is sized for use in industrial, commercial, and heavy-duty residential electrical panels and disconnect switches. Licensed electricians and electrical contractors install this type of fuse as part of branch-circuit or feeder protection schemes where standard fuse classes do not meet the required interrupt rating.

Class T fuses are commonly installed in motor control centers, disconnect switches, and electrical distribution panels where a compact footprint and high interrupt capacity are priorities. The A3T175 is suited for applications requiring a 175-amp current rating. This fuse is typically specified in commercial and industrial settings where fault current levels demand current-limiting overcurrent protection devices.

Key Features

• Class T current-limiting fuse with high interrupt capacity
• Fast-acting response helps limit fault energy and protect downstream equipment
• Compact form factor fits tight panel and disconnect enclosures
• Rated at 175 amps for branch-circuit and feeder protection applications
• Suitable for industrial, commercial, and heavy-duty residential electrical systems

Compatibility

Designed as an OEM-style replacement Class T fuse for use in electrical panels, motor control centers, and disconnect switches requiring a 175-amp Class T rated overcurrent protection device.

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 before removing or installing any fuse. Verify that the replacement fuse matches the required voltage and amperage rating before installation. Do not install a fuse with a higher amperage rating than the circuit is designed to carry.
