Working Mechanism

  • In the event of a short-circuit or overcurrent condition, the current flowing through the fuse exceeds its rated limit.
  • This causes the fuse element to melt and open the circuit.
  • As the element melts, it interrupts the current flow and prevents further damage to the transformer and connected equipment.

Frequently Asked Questions

What is the function of a 2-pole CC fuse block?

A 2-block Class CC fuse block is designed to hold and connect two Class CC fuses in an electrical circuit. It protects both the line and load sides of a circuit with a single device from faulty currents.

What are dry-type distribution transformers?

These transformers are used to step down the voltage in power distribution systems, commonly used in commercial and industrial facilities. They are called dry-type because they do not use liquid coolants such as oil or PCB, which causes a risk of fire hazards due to leakage or spills. Instead, they rely on air or gas for cooling and can be easily installed in tight spaces.

What are non-rejection transformers?

Non-rejection transformers do not have the ability to withstand momentary overload or overvoltage. They are designed to operate under normal steady-state conditions. Therefore, they require a primary fuse connection to protect them from damage due to electrical faults.
