0315.031VXP

0315.031VXP fuses are medium-voltage class RK5 fuses used for fault protection of measure and control circuits in medium-voltage distribution systems. Although these fuses might appear to have a simple working principle, they play an important role in reducing the risk of fire, electric shock, and serious equipment failure.

Application Fields

0315.031VXP fuses are designed for medium-voltage distribution systems up to 36 kV. The maximum current rating can vary, so check with the manufacturer in order to ensure that the fuse is suitable for the application. Typical applications include overcurrent protection for transformers, generators, capacitor banks, busbar protection, and starting of medium-voltage motors.

Working Principle

0315.031VXP fuses are current-limiting type fuses. When an overcurrent is detected, the fuse element melts and disconnects the circuit in order to protect the equipment and reduce the risk of a fire. The operating time of the fuse is very short and is usually much lower than the operating time of circuit breakers.

The fuses are designed with a calibrated time-current characteristic in order to limit the ampere-seconds of the short circuit current in order to avoid damage to connected equipment. The operating time of the fuse also depends on the magnitude of the short-circuit current, the fuse size, and the point where the short is located.

0315.031VXP fuses are suitable for use in series with switches, circuit breakers, and other protection devices. The fuse element is constructed from two pieces of wire, or fusible links, which are connected in series with each other. When an overcurrent is detected, the wires melt and the current is disconnected in order to protect the connected equipment.

0315.031VXP fuses provide reliable protection against overheating, overvoltage, and short circuits. They are designed for long-term use under harsh conditions and can be used to protect a variety of medium-voltage distribution systems. The fuse size should be selected according to the type of application in order to ensure proper protection of the equipment.
