Fuses are important protective devices used in power systems to protect equipment against overload and short-circuit. The 0672.125DRT4 is a fuse specifically designed to protect electronics and automation from the hazards of short-circuiting and overvoltage. It works by, essentially, opening the circuit between the source and the intended destination when there’s an excessive current or voltage spike. They are particularly useful for installation in human-interactive application, such as medical equipment, where short-circuited wires could shock users.

The 0672.125DRT4 is rated with an operating voltage of 850 Volts AC, with a maximum voltage of 1000 Volts AC. The fuse body is a UL-rated 94V-0 plastic material, which makes it highly weather- and impact-resistant. The 0672.125DRT4 also has a unique feature -- a tamper-proof button, enabling safer installation in high-risk areas. This provides extra protection against accidental disassembly or tampering.

In terms of applications, the 0672.125DRT4 is ideal for use in sensitive electronic equipment, particularly those with a ground-based firm connection. The fuse is also great for protecting against power surges and other unexpected and potentially hazardous voltage or current spikes. In addition, the 0672.125DRT4 is also commonly used in various industrial automation and process control systems for added safety.

In regard to its working principle, the 0672.125DRT4 consists of a metal strip and internal strip that are connected by a crimped contact at each end. When the fuse is “blown” or tripped, the internal strip melts by absorbing the excessive current or voltage, thus opening the circuit. This prevents any short-circuited or overvoltage from traveling further down the line, thus protecting the system.

In summary, the 0672.125DRT4 is a UL-rated, 850-volt AC fuse designed for protecting sensitive electronics and equipment from the hazards of overvoltage and short-circuiting. Its tamper-proof button provides extra security and safety when used in human-interactive applications, such as medical devices. The fuse is also great for various industrial automation systems, as well as any other facility with connections that are prone to high current or voltage problems. Its working principle involves an internal strip melting by absorbing excess current or voltage when a circuit is blown, thus “opening” the circuit and preventing any further damage to the system.
