Description

The Fuse is an electrical component designed to protect electrical circuits from excessive current flow. It consists of a small cylindrical body made of glass or ceramic with metal end caps. Inside the fuse is a thin metal strip or wire called the fuse element, which has a specific current-carrying capacity, When the current passing through the fuse exceeds its rated value of 20 amperes, the fuse element heats up due to the resistance of the metal. If the current remains excessive for a certain period, the fuse element will reach its melting point and quickly melt, breaking the circuit. This action effectively disconnects the circuit and stops the flow of electricity, preventing damage to connected devices and wiring. The 20-ampere fuse is commonly used in electrical devices, appliances, and fuse boxes to provide a safety measure against overcurrent situations. When a fuse blows, it needs to be replaced with a new one of the same current rating to maintain proper protection

Attributes:
• Prevents damage to electrical equipment and wiring during short circuits or overloads
• Requires no external power source or maintenance once installed
• Easy to install and replace when needed
• Voltage rated to 600 Maximum, interrupting rating in AC at 100 KA, and DC at 50 KA

Applications:
This Fuse is to protect electrical circuits from excessive current and prevents damage to equipment and wiring.

Warning:This product can expose you to chemicals including Lead and lead compounds, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
