PTC Resettable Fuses are a type of electrical current protection device that work to protect circuits, equipment, and wiring from overloads and short circuits. This type of fuse is different from other standard fuses in that it can be reset after tripping and then used again, making them a cost-effective and safe solution for protecting electrical devices. The 250R120TU is a PTC Resettable Fuse that has a wide variety of applications and functions.

The 250R120TU PTC Resettable Fuse is commonly used in power supplies, electronic circuits, telecom systems, and industrial automation systems. It has an AC or DC voltage rating of 250V and a rated operating current of 0.6A. This fuse is also constructed for low contact resistance, making it a reliable choice for a range of applications.

The 250R120TU works on the principle of thermal-magnetic protection. This working principle combines the action of an electromagnetic trip point and an electrically heated, self-resettable element. When a short circuit or overload occurs, this causes an increase in the current flow and energy to the fuse. This creates a magnetic force that trips the trip point, opens the circuit, and stops the flow of current.

The thermal element then begins to heat up. This occurs in response to the increased current flow and energy. When the fuse reaches a certain temperature, the element automatically opens and the current flow is interrupted. The self-resettable element then cools off, resets itself, and then enables current flow again. This process of heating and cooling creates a reliable level of overload protection and keeps the fuse from permanently burning out.

The 250R120TU is a reliable choice as a PTC Resettable Fuse for a variety of applications as it is designed to provide a high level of protection while making the cost and installation process more affordable. It also reduces the risk of short circuits and overloads, minimizing the danger of equipment malfunctions, fires, or electrical shock. The wide operating temperature range and low contact resistance of the 250R120TU make it an ideal choice for protecting circuits, equipment, and wiring from electrical overloads and short circuits.
