Fuses

0675004.MXEP application field and working principle

Fuses are widely used in many electronic devices to protect them from voltage and current overloads. The 0674004.MXEP is a medium-breaking, non-reclosing, time-delayed, interchangeable circuit breaker fuse widely used in automotive and power-control applications.This fuse is designed for use in medium-voltage circuits with 500VAC or 600VDC, and is rated up to 40A. The fuse is UL-listed, UL-recognized, CSA-certified and is in conformance with the IEC-60269-1 standard. The product is approved for worldwide use.The basic working principle of 0674004.MXEP is to provide over-current protection and protection from short-circuits. The fuse as a safety device for circuit disconnection has been known for a long time. The fuse operating principle is to provide a set of two blades of specific size for a certain current rating. In the normal operating conditions, the fuse will conduct the current, while in the event of an overload or short-circuit, the fuse will break the electrical connection and disconnect the circuit.The 0674004.MXEP fuse features an adjustable time delay that allows for the selection of the desired delay time for either over-current or short-circuit protection. The time delay prevents nuisance tripping of the fuse due to momentary fluctuations of the current. The fuse body is made of ceramic with silver coating that ensures better reliability in harsh temperature environments. The fuse is designed with a metal strip attached to the contact-tip, which ensures zero-shift at the contact surface.The 0674004.MXEP fuse is used in various types of power-control applications including motor control circuits, power electronics application, and industrial automation system applications. In motor control circuit, the fuse is used to provide protection from both overload and short-circuits. In power electronics application, the fuses are used for current limiting to avoid the damage of the power supply from the surge of the output current. In industrial automation system, the fuses are used to protect the system’s output devices from fluctuation, e.g. relay, motor, and solenoid.In conclusion, the 0674004.MXEP is a high performance medium-breaking, non-reclosing, time-delayed, interchangeable circuit breaker fuse designed for use in various applications with 500VAC or 600VDC. The adjustable time delay provides reliable protection with minimal nuisance tripping. The fuse is UL-listed, UL-recognized, and CSA-certified for worldwide use. The fuse is widely used in motor control circuits, power electronics application, and industrial automation system applications.
