The TR1/6125TD4-R is an auto-resetting fuse with current and voltage limiting capabilities. It is designed to protect power and other electrical components from excessive current or voltage levels that could otherwise damage them. The TR1/6125TD4-R has a voltage rating of 125V and a current rating of 2A, and its design features a direct acting resistor that trips when current or voltage increases, which then resets itself once the current or voltage level falls to a safe level. The TR1/6125TD4-R is commonly used to protect power supplies, such as those found in automotive applications, computers, and other electrical equipment.

The TR1/6125TD4-R is a fusible element that contains a fuse wire element and a protective connector. The fuse wire element is made of a metal material that melts when it is exposed to an overload or over-voltage condition. As the two ends of the wire come into contact, it creates a high resistance path and the current flow is broken. The protective connector allows the current to pass through the fuse when it is intact.

The TR1/6125TD4-R\'s current-limiting capability is enabled when the current exceeds the set limit, usually when faults or short circuits occur. When the overload occurs, the fuse wire element inside the fuse melts, creating a high resistance path and restricting the current to some degree. The current is then limited to the fuse\'s rated level until the overload is cleared or the fault is cleared.

The voltage-limiting capability of the TR1/6125TD4-R, meanwhile, works when the voltage exceeds the set limit, usually during abnormally high surge events. When this occurs, the fuse wire element melts, creating a high-resistance path and reducing voltage to a safe level. The fuse is designed to reset itself as the voltage returns to normal, enabling the circuit to be resumed without the risk of further damage or overvoltage.

The TR1/6125TD4-R has a higher current rating than standard fuses, and its direct acting resistor trips quickly and enables the self-resetting function. This makes it an ideal choice for automotive applications and power supplies where the current flow must be limited and quickly reset in the event of overload or overvoltage conditions. These features combine to provide the user with a highly reliable fuse that will protect their power supplies and other electrical components from damage.
