Fuses

In many industries, electric circuits are a common component of operations, and electric safety and protection is a necessary consideration. Fuses are among the oldest and most reliable safety devices designed for these circuits. They exist in two primary forms: cut-out fuses and circuit breakers.

0034.3627 Application Field and Working Principle

The 0034.3627 fuse is a type of conventional cut-out fuse with a three layer structure. It is commonly used for low voltage distribution circuit protection, particularly in AC distribution systems comprising loads such as lighting and air conditioning equipment. It is designed for use within a molded case switchgear, and its primary purpose is to provide short-circuit protection from any overloads. The 0034.3627 fuse has a working voltage of 400V AC or DC and is rated for a breaking capacity of 25kA.

A 0034.3627 fuse consists of a stamped brass element, a ceramic insulating tube, and two metal end caps. The element is typically red or yellow in color and consists of 2-4 sets of strips with a terminal end. When the current through the element reaches the rated level, the resistivity causes these strips to heat and melt. This interrupts the flow of electricity and thus disconnects the circuit.

Each 0034.3627 fuse is also equipped with a safety device known as an arcing chamber. This chamber is designed to contain any arc that might be generated during the operation of the fuse and to disperse it in a manner that reduces the risk of injury to personnel and damage to equipment. The arcing chamber helps to ensure that the switchgear is not damaged, and can also absorb and disperse any electromagnetic disturbances that may arise from a short circuit.

For safety, users should periodically inspect the 0034.3627 fuse against the applicable standard. Visual checks should be performed to ensure there is no physical damage, that the fuse element is not cracked or loose, and that the terminals are in good condition. The integrity of the protective arcing chamber should also be confirmed.

In summary, the 0034.3627 fuse is a dependable and effective safety device that helps to protect electrical circuits from short-circuits, overloads, and electromagnetic disturbances. It is a key component in the safety of low voltage AC door distribution systems, and should be inspected on a regular basis to ensure its continued functionality.
