Cooper Bussmann FWH-200B Cartridge Fast-acting Fuse 200A

Product Description

The COOPER BUSSMANN FWH-200B is a 200-amp cartridge fast-acting fuse rated for high-current protection in industrial and commercial electrical systems. Measuring 3-5/8 inches in overall length and using a bolt-on mount configuration, this fuse is engineered for reliable overcurrent protection where rapid interruption is critical. The fast-acting response characteristic makes it well suited for protecting semiconductors, drives, and sensitive power conversion equipment. It carries CE certification, CSA Component Acceptance under File 53787, and UL Recognition under Guide JFHR2 File E91958, meeting the compliance requirements common in industrial installation environments.

This fuse is typically installed in industrial control panels, variable frequency drives, power supplies, and other equipment where fast-acting fuse protection is specified. The bolt-on mount design allows secure, low-resistance termination in busbars and fuse blocks rated for this class. Licensed electricians and industrial maintenance technicians are the primary installers. It is sold in a minimum order quantity of 5 units, with individual package quantity of 1.

Key Features

• 200-amp continuous current rating for high-load circuit protection
• Fast-acting fuse timing for rapid response to overcurrent events
• Bolt-on mount for secure busbar or fuse block termination
• 3-5/8 inch overall length in a standard cartridge body
• CE Certified, CSA Component Accepted, and UL Recognized
• 50 kA interrupting rating at DC (RMS symmetrical)

Compatibility

Designed as an OEM-style replacement for bolt-on cartridge fuse positions rated at 200 amps in industrial fuse blocks and power distribution equipment requiring fast-acting protection.

Installation Notes

Installation should be performed by a licensed electrician following applicable NEC requirements. De-energize and lock out the circuit completely before removing or installing any fuse. Verify that the fuse block or holder is rated for the bolt-on mount style and the 200-amp current class before installation. Do not attempt to replace a fast-acting fuse with a time-delay type without confirming the protected equipment specifications allow the substitution.
