25D27 fuses are high-capacity, dual-element, time delay fuses. The fuses are available in rated currents from 1 to 2000. Typically, these type fo fuses are applied in circuits up to 600 volts, AC and DC for overcurrent protection and control circuit requirements. They have class R features: Time-Delay, Current Limiting, & Protects Varistors and Resistors.

The 25D27 type is UL listed, CSA certified, and meets all the requirements of UL 248-18. The fuse satisfies the requirements for the Marine Equipment Directive and also provides UL thermal cycling & transient overvoltage resistance, allowing the breaker to be used for global applications. These fuses are fully compliant with IEC 60934-2019 and CE low voltage directive.

The 25D27 fuse works by providing a current limiting time delay action that helps to protect electrical circuits, equipment, and personnel in the event of an overcurrent condition. When the current exceeds the rated fuse value the central element melts and interrupts the circuit flow. The arc created by the interruption is suppressed or quenched by the outer element of the fuse and the circuit is rendered open.

Another advantage of using the 25D27 fuse is its fused element design. This helps to minimize the clearance requirements for nearby components and thus helps reduce the overall size of the assembled equipment. The 25D27 fuses are also resistant to shock and vibration, which increases the safety and longevity of the protected circuit.

25D27 fuses are ideal for a variety of applications such as motor control, AC and DC drives, uninterruptible power supplies (UPSs), lighting systems, and process control applications. The 25D27 is a popular and efficient choice for a wide range of markets including telecommunications, industrial, distribution, and automotive. When compared to other kinds of fuses these tend to cost less, be easier to install, and provide superior performance over a long service life.

The 25D27 fuse offers an efficient and economical solution for primary and secondary protection in circuits up to 600V AC and DC, and with a current rating of up to 2000A. This fuse has superior short-circuit-current-limiting characteristics and will withstand severe current overloads and transient conditions that other fuses cannot. The fuse has low let-through energy, making it an ideal and reliable choice for primary and secondary protection in a wide range of equipment, including motor control, AC and DC drives, lighting systems, power supplies, and process control circuits. Additionally, the fuse is fully compliant with IEC 60934-2019 and meets all the requirements of UL 248-18.
