TR2/C518S-5-R

Fuses are a vital part of electrical safety equipment, and TR2/C518S-5-R is an excellent example of such safety equipment. Its secure construction, extensive safety features and range of applications make it a popular choice for both residential and commercial assemblies. In this article, we’ll explore the TR2/C518S-5-R application field and working principle.

The TR2/C518S-5-R is a miniature, UL-listed, time-delay, dual-element, 150VAC rated, dual-rated 1/2”x1-1/4” (popularly known as TR2) fuse with a 10A amp rating. It has a maximum current interrupting capability of 10,000A at 150V AC. The popularly used spacing between the contacts is 1/4”, but there are also models with a spacing of 1/2”. It is made with a single-mount phenolic UL rated plastic body, which makes it suitable for use in limited-space electrical circuits.

In terms of application, the TR2/C518S-5-R is intended for use in circuits that require overcurrent protection from 15A to 30A, at 120/240V AC or DC. It can be used on residential branch-circuit, commercial motor equipment, and other limited-space applications. It is suitable for use in a wide range of residential, commercial, and industrial circuits. It is also suitable for use in the appliance, general circuit control, motor control, and heating and cooling system industries.

The application field of the TR2/C518S-5-R includes motor control panels, swimming pool heaters, and air conditioning units. It is UL and CSA Listed and RoHS and CQC-approved. It can be safely used in a variety of environments, such as indoor and outdoor applications, and it can even be used in wet and damp locations.

The working principle of the TR2/C518S-5-R fuse is based on the thermoplastic technology. Its heating element is made of a low-melting-point alloy, surrounded by a high-temperature plastic housing. When a high current passes through the heating element, the heat generated due to the high current causes the plastic housing to expand and press against the contacts, thereby breaking the connection and making the circuit “dead”. The melting of the low-melting point alloy further ensures that the circuit remains dead until the fuse is replaced, as the contacts cannot be re-closed until a new fuse is inserted.

The TR2/C518S-5-R fuse is a great choice for circuit protection applications due to its heavy-duty construction and secure installation. It can protect circuits against overcurrent, short-circuiting, and reverse currents. It is also very easy to install due to its modular construction, and it is very affordable, making it a great value for any residential or commercial application.

In conclusion, the TR2/C518S-5-R is a versatile, UL-listed, time-delay, dual-element, 150VAC rated, dual-rated 1/2”x1-1/4” fuse. It has an extensive application field and it is made with a single-mount phenolic UL rated plastic body, which makes it suitable for use in limited-space electrical circuits. It features the thermoplastic technology, making it suitable for circuit protection applications. It is very easy to install and very affordable, making it a great value for any application.
