Introduction

70-FUSE-3AC is a series of accessories designed to be used in several applications to provide protection for electrical circuits in industrial, commercial and residential applications. The product series is certified, tested and approved by UL, CSA, TUV, NIC, KEMA and CE. This type of product is extremely popular and widely used in many kinds of applications where circuit protection, power distribution or over-current protection is needed. The 70-FUSE-3AC accessories typically consists of three components: the base, the fuse and a mounting clip.

Application Fields of 70-FUSE-3AC

70-FUSE-3AC is a popular over-current protection device that is widely used in different areas such as:

• Automotive and Marine Applications: 70-FUSE-3AC is often used in vehicles, recreational vehicles, and marine applications to protect electrical circuits. It is designed to provide over-current and short-circuit protection in these applications.
• Industrial Applications: It is used for over-current protection of motor controllers and industrial control circuits. It is also used to provide power failure protection.
• Residential Applications: 70-FUSE-3AC is the most common form of over-current protection used in residential applications. It is used to protect house wiring circuits from over-current and short-circuits.
• Commercial Applications: 70-FUSE-3AC is used in commercial applications to protect the building wiring, lighting, air conditioning and heating systems from over-current and short-circuits. It is also used to protect breakers and transformers from over-current and short-circuits.

In all these applications the 70-FUSE-3AC accessories provide reliable over-current protection and thus ensures safety and reliability.

Working Principle of 70-FUSE-3AC

The working principle of 70-FUSE-3AC is based on the standard fuse principle, where a current-carrying element is an embedded strip of metal known as a fusible link. The fusible link is connected in series with the circuit and when the current in the circuit exceeds the rated current of the fuse, it will heat up and melt. This will cause a break in the circuit and thus protect the circuit from over-current.

The 70-FUSE-3AC also utilizes a special type of thermal element known as a Bi-Metal Strip. This strip is a two-layered strip made of two different metal alloys with different melting points. When the temperature in the circuit rises, the Bi-Metal strip will heat up and cause the internal connection to break. This will cause a break in the circuit and protect it from over-current.

The 70-FUSE-3AC is designed to provide reliable over-current protection and to ensure safety and reliability in the circuit. It is a reliable and cost effective way to protect your circuits from over-current.
