0466.250NRHF

Fuses

0466.250NRHF is a type of fuse used to protect electric circuits from excess current, overload and damage. This fuse is generally used in low voltage power systems for protection against short circuits, overcurrents, and voltage overloads. It is composed of a wire element, a current sensitive element, and a fuse case. It is capable of responding quickly to over current events and interrupting power before damage can occur.

Application Field:

0466.250NRHF fuses are typically used to protect cables from overcurrents and short circuits in low voltage power systems. They are commonly used on lighting systems, household appliances, outdoor lighting systems, and emergency generators. This fuse is also suitable for applications where remote indication of overcurrents or faults is desirable.

Working Principle:

The fuse works by having the current sensitive element act as a switch that can be opened or closed in the case of an overload. When an over-current occurs, power flows through the current sensitive element, which heats due to the current and opens the contact, thereby interrupting the power. The current sensitive element is designed to open quickly and recover, allowing normal operation when the fault is removed.

Advantages:

0466.250NRHF fuses offer several advantages over other types of circuit protection:

• Fast response
• High current interrupting capability
• No over-current sensing needed
• Easy to install
• Low cost

Disadvantages:

Though 0466.250NRHF fuses offer many advantages, they have several drawbacks including:

• Reduced current carrying capacity when compared to other types of circuit protection
• No information available as to the cause of failure
• Can be triggered by normal load currents in some applications
