Mersen a13x200-4 Semiconductor Fuse 200A 130VAC

Product Description

The MERSEN a13x200-4 is a fast-acting, round-body semiconductor protection fuse rated at 200 amperes and 130 volts AC. It is designed for the specific protection of diodes, SCRs, and other semiconductor devices in power conversion equipment. The fuse features a bolt-in blade terminal connection, a built-in blown-fuse indicator, and an 8 kiloampere (AC) interrupting rating. Its compact cylindrical form measures 2.66 inches in length and 1.13 inches in diameter, making it well suited for enclosures and panel assemblies where space is limited. Licensed electricians and industrial maintenance technicians are the primary installers of this component.

The a13x200-4 belongs to the MERSEN A13X AMP-TRAP series, engineered for North American-style fuse applications in the 130 VAC class. Typical installations include electrochemical rectifier protection, power supply units, variable frequency drives, and other heavy-duty devices where semiconductor components require fast-clearing overcurrent protection. The compact round design accommodates installations with restricted mounting space without compromising protection performance.

Key Features

• Fast-acting characteristics for rapid semiconductor protection during overcurrent events
• 200 ampere current rating at 130 VAC
• 8 kiloampere (AC) interrupting rating for high fault-current environments
• Built-in blown-fuse indication for quick fault identification without meter testing
• Bolt-in blade terminal type for secure, low-resistance panel mounting
• UL approved construction meeting North American safety standards
• Compact round body: 2.66 inches long, 1.13 inches in diameter

Compatibility

Designed for protection of heavy-duty devices such as electrochemical rectifiers, diodes, and other semiconductor devices rated at 130 VAC. Part of the MERSEN A13X product line for North American-style semiconductor fuse applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit before removing or installing any fuse. Verify that the replacement fuse ampere rating, voltage rating, and interrupting rating match the original specification before installation. Do not use this fuse as a substitute for a general-purpose fuse in circuits it was not designed to protect.
