Cooper Bussmann FWX-175A Fast-acting Fuse 175A Stud Mount

Product Description

The COOPER BUSSMANN FWX-175A is a flush end, fast-acting fuse rated at 175 amps with an overall length of 3-1/8 inches. It is designed for stud-mount installations in industrial power distribution, motor control, and heavy electrical equipment panels. Fast-acting fuses like the FWX-175A provide immediate overcurrent protection with minimal delay, making them suitable for circuits where downstream components cannot tolerate extended fault current exposure. Licensed electricians and industrial maintenance technicians are the primary installers of this fuse type. It carries CE, CSA, and UL recognition, confirming compliance with major North American and international electrical standards.

The FWX-175A is appropriate for use in commercial and industrial electrical systems where stud-mount fusing is specified. Typical applications include DC bus protection, semiconductor equipment circuits, and high-current branch circuit protection. The flush end body style is compatible with standard fuse holders and blocks designed for this fuse form factor. It is well suited for retrofit and new-installation scenarios in industrial control panels and power conversion equipment.

Key Features

• 175 amp continuous current rating for high-current circuit protection
• Fast-acting response characteristic for immediate overcurrent interruption
• Flush end body style for use with compatible stud-mount fuse holders
• 50 kA interrupting capacity at DC for robust fault current handling
• CE Certified, CSA Certified, and UL Recognized (Guide JFHR2, File E56412)
• Overall length of 3-1/8 inches for standard panel and holder fitment

Compatibility

Designed as an OEM-style replacement for stud-mount, flush end fast-acting fuses in industrial power distribution panels and motor control equipment requiring a 175 amp, fast-acting fuse with a 3-1/8 inch overall length.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lockout-tagout the circuit before removing or installing the fuse. Confirm that the fuse holder or block is rated for stud-mount, flush end fuses and is suitable for the circuit voltage and current. Do not substitute a fuse with a different amperage rating, interrupting rating, or fuse timing characteristic.
