Semiconductor Fuse, 500A, Fast-Acting, 300V AC, Bolt-On
Protect your high-power electronics with the Mersen Semiconductor Fuse, a fast-acting, non-indicating fuse designed for reliable circuit protection. Rated for 500A and 300V AC, this fuse is ideal for applications where high current and voltage are present, such as in industrial control systems, motor control, and power supplies. Its fast-acting response time ensures safe shutdown in the event of an overload, preventing damage to equipment and reducing downtime. With a compact bolt-on design and high interrupt ratings, this fuse is a reliable choice for demanding applications, including those in the aerospace, automotive, and renewable energy industries.
Top product features:
- Fast-Acting design interrupts electrical current quickly in the event of an overload or short circuit
- Non-Indicating design means the fuse does not visually indicate when it has blown
- Interrupt Rating of 100kA at 300V DC and 200kA at 300V AC provides high current interruption capability
Top product applications:
- Power Supplies
- Industrial Control Panels
- Motor Control Circuits
