Product Description

The BUSSMANN KAC Series Semiconductor Fuse is a fast-acting, bolt-on fuse rated at 300 A and 600 V AC. This non-indicating fuse, model KAC-300, is designed for AC-only applications requiring overcurrent protection for semiconductor devices.

Frequently Asked Questions

What is the BUSSMANN KAC-300 semiconductor fuse used for?

The BUSSMANN KAC-300 is a fast-acting, bolt-on fuse designed to protect semiconductor devices such as diodes, thyristors, and IGBTs from overcurrent faults in AC circuits. It is commonly used in industrial power supplies, motor drives, and UPS systems where rapid clearing of high fault currents is critical to prevent damage.

What are the specifications of the BUSSMANN KAC-300 fuse?

The BUSSMANN KAC-300 is a KAC Series semiconductor fuse rated at 300 A and 600 V AC. It is a fast-acting, non-indicating, bolt-on fuse with AC-only voltage type. The manufacturer part number is KAC-300. This fuse provides reliable overcurrent protection for power electronics in industrial environments.

Where to buy the BUSSMANN KAC-300 fuse worldwide?

3G Electric supplies the BUSSMANN KAC-300 fuse to customers worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your location. Contact our team to place an order or request a quote for this fast-acting semiconductor fuse.

How to select the correct BUSSMANN KAC series fuse for an application?

To select the correct BUSSMANN KAC series fuse, verify the system voltage is AC only and does not exceed 600 V AC. Ensure the continuous current rating matches or exceeds the load current, typically 300 A for the KAC-300. Consider the fuse's fast-acting characteristic to protect sensitive semiconductors from short-circuit currents.
