0257001.U Datasheet/PDFFuses
A fuse is an electrical safety device designed to protect circuits from overloads. It works by breaking an electrical circuit if the current through the fuse exceeds a predetermined value.
0257001.U Application Field and Working Principle
The 0257001.U is a fast-acting fuse used in applications such as lighting systems, heating systems and air-conditioning systems. It is designed to detect and protect against short circuits, overloads and other faults in such applications. The 0257001.U is a ceramic-housed, time-delay fuse with a fast-acting internal element or "disc." When the current passing through the fuse exceeds its rating, the disc melts, causing an electric arc that vaporizes the contact surfaces and breaks the circuit. When the current returns to normal, the circuit is automatically re-established.
The 0257001.U is used for short-circuit protection, such as when there is an accidental shorting of wires in a system. When excessive current passes through the fuse, the disc melts and the circuit is broken immediately. This prevents further damage to the circuit, thereby preventing the system from suffering permanent damage. The 0257001.U is also used to protect circuits from overloads. If the current exceeds a certain limit, the disc melts and the circuit is broken.
The 0257001.U has a current rating of 13A with a current limitation of 10A. It operates up to a voltage rating of 240V with a voltage range of 5V to 250V. The fuse is constructed from ceramic material with a nickel-plated contact surface and a silver-plated terminal. The fuse can be identified by its blue top mark and white bottom mark. The 0257001.U is designed to break the circuit in a fraction of a second, making it an effective protection device against short circuits and overloads.
The 0257001.U is a relatively low-cost device which provides an excellent level of protection against faults in applications such as lighting systems, heating systems and air-conditioning systems. It operates reliably, quickly and safely, with a breaking time of just a few milliseconds. In addition, it is resistant to shock, vibration and corrosion, making it a suitable choice for harsh environments. The versatility of the fuse allows it to be used in a wide range of applications.
In conclusion, the 0257001.U is a fast-acting fuse used to protect circuits against short circuits, overloads and other faults. It is designed to break the circuit in a fraction of a second, providing an effective level of protection. It is reliable, fast and shock-resistant, making it a suitable device for a variety of applications.
