Fuses

Fuses are components used to protect electrical circuits from abnormal overloads or short circuits. They serve as a vital part of any electrical system and are designed to function automatically by disconnecting the power source when abnormal conditions are detected. Fuses come in many different types and designs, but the most common is the 2JQ 7.

2JQ 7 Application Field and Working Principle

The 2JQ 7 fuses are commonly used in residential and industrial electric circuits as well as in control systems. These fuses are typically made from zinc-plated steel and feature internal contacts that provide electrical connection. The main function of these fuses is to protect electrical equipment from overheating and short circuits, preventing the possibility of damage and fire in critical areas.

2JQ 7 fuses work in a way that upon reaching a certain predetermined current, the fuse is automatically ruptured, disrupting the flow of electricity. This is usually done by melting an internal fuse wire until it breaks, creating an open circuit. The new connection stops the electron flow and protects the equipment from further damage.

These fuses are designed and manufactured to meet UL 98 and IEC 127 standards for safety, and they are tested to ensure they meet established requirements. As a safety feature, 2JQ 7 fuses are normally installed in series, so even if one fuse becomes defective or is damaged, the other will remain to protect the system from a catastrophic failure.

2JQ 7 fuses are available in a wide range of ratings, from 5A to 30A, allowing them to be used in different electrical systems and applications. These fuses are also designed to work with corresponding holders, so they can be easily installed throughout the circuit quickly and without any additional tools or hardware.
