0697H4000-02

Fuses are essential pieces of electrical safety equipment, serving to disrupt an electric circuit when it becomes overloaded or abnormally short-circuited. The 0697H4000-02 current-limiting fuses protect against overloads and extreme short-circuits. This article will discuss the application field and working principle of the 0697H4000-02 current-limiting fuses, as well as some of the safety features it provides.

Application Field

The 0697H4000-02 current-limiting fuses are designed for protection of low and medium voltage power distribution systems, such as those found in industrial, commercial, and residential power supplies. The 0697H4000-02 current-limiting fuses are particularly suited for applications that require limitation of fault current to protect vulnerable circuits. For example, a fault downstream of the 0697H4000-02 current-limiting fuse may be sufficiently isolation from the rest of the system, to minimize the effect of the fault.

The 0697H4000-02 current-limiting fuses is UL 489 listed, and CSA certified for supplemental protection of low voltage distribution systems. The fuse is rated for 1000 Volts AC, and is suitable for use in an application such as in a 10 Kilovolt-Amps (kVA) system. The fuse is also suitable for use in high impact installations, such as in power stations and distribution networks.

Working Principle

The 0697H4000-02 current-limiting fuses work on the principle of thermal overload and extreme short-circuit protection. When an overload or a short circuit occurs beyond the normal current load, the fuse is designed to open quickly, interrupting the circuit and protecting it from further damage.

The 0697H4000-02 current-limiting fuses are designed to limit the peak fault current that flows through the fuse when an overload or a short circuit occurs. In so doing, they offer the downstream devices in the circuit, such as circuit breakers or other devices, protection from high-current damage. This is important for particularly vulnerable circuits, such as those involved in communication, control, or data transmission.

The 0697H4000-02 current-limiting fuses also offer protection from secondary fault current. When a fault current passes through the fuse and an overload or a short circuit occurs, the fuse is closed, and the damaged section of the system is isolated from the rest of the system. This eliminates the risk of secondary fault currents that could otherwise cause serious damage.

Safety Features

The 0697H4000-02 current-limiting fuses offer significant safety features to help ensure that the systems they protect are protected from overloads and extreme short-circuits. In particular, they are designed to limit excessive fault currents in an effort to minimize damage to the system and components.

The 0697H4000-02 current-limiting fuses also feature temperature-compensated fusibly-linked current breaking elements. This helps to ensure that the fuse is able to quickly open and clear the circuit when a fault occurs. This helps to protect the system and components from potential damage due to excessive fault currents.

Finally, the 0697H4000-02 current-limiting fuses are extremely resilient. They are designed to withstand extreme temperatures, vibration, shock, and humidity. This helps ensure the long-term reliability of the fuse, and in turn, the systems and components it helps to protect.
