ECL055-20E Application Field and Working Principle

The ECL055-20E Specialty Fuse is a product of the Eaton Corporation and is a general purpose branch circuit fuse. It is typically used to protect against potentially dangerous overcurrent conditions caused by short circuits, allowing enough current to flow to operate electrical appliances and other devices while isolating them from too much current that can cause surges and damage.

The ECL055-20E is a 1/2" x 13/32" (13 x 10.3 mm), single pole, single element time delay fuse (MIDGET size) and comes with a standard 200VAC/50VDC rating. It has a time-delay characteristic that allows current to flow for a short time before opening; this allows short-duration transient and motor starting currents to be tolerated.

ECL055-20E fuses can be used in a wide variety of applications ranging from motor-protecting circuit breakers, vending machines, industrial and commercial power supplies, lighting circuits, industrial control systems, industrial machinery and amusement arcade game machines. It is also suitable for consumer applications such as air conditioners, refrigerators, washing machines, microwave ovens.

The working principle of the ECL055-20E fuse is quite simple. When a fault occurs and the current passes through the fuse, the metal element- usually made of silver- will be heated, melting the connector between two fuse elements. The melted portion will open, making insulation between the two elements, thus breaking the circuit and preventing further current flow.

The operating time depends on the current magnitude and the size of the fuse. The fuse can also be tested with a continuity tester to determine if the fuse is still in good working condition or has tripped. It is also important to regularly check the fuse for proper operation to ensure the safety of the equipment.

The ECL055-20E fuse is available in a variety of sizes and amperage ratings, though it is most commonly seen with a rating of 3/4 amps. It is a UL approved fuse and is recognized by the Canadian Standards Association (CSA). Its performance is backed with a 2-year warranty.

The ECL055-20E fuse is an efficient, yet inexpensive solution for circuit protection needs. It is suitable for various power supplies and possible dangerous current conditions. Its affordable and durable construction makes it a reliable device for many applications.
