ReferencesFuses are safety devices that are used to protect electrical circuits from damage caused by excessive current. These devices are designed to operate on current overloads, so that if the current overload exceeds a programmed limit, the connection between the circuit and the power source is broken, thus protecting the circuit from further damage.AGA-7 is a type of fuse which prevents high currents (e.g. caused by short circuits) from damaging electric circuits. It is specifically designed to prevent fires caused by high current, in the most hazardous locations.The common application field of AGA-7 fuses is a circuit where high current is typically charaterised by high frequency or large duration current spikes. Examples include:• Industrial Motors• Photovoltaics• Electronic energy meters• Control systems• Automotive applications• Installation of power systemsThe main purpose of the AGA-7 fuse is to protect equipment from over current surge, thermal overload and short circuit conditions. It is widely used in the industry, as a self-protection device in DC and AC circles.The overall working principle of the AGA-7 fuse is to divert excessive current away from the circuit by deactivating the overload component of the circuit, thus limiting the build-up of energy and preventing damage to the associated equipment. This is achieved by using a specific assembly of components, including a polymeric substance, a metal-oxide coating and an insulation layer.The polymeric substance of the AGA-7 is a material with high thermal conductivity and stability. The purpose of this substance is to create a physical barrier between the two poles of the fuse. This material is designed to melt rapidly under high current and thus disrupt the current supply, disconnecting power from the circuit.The metal oxide coating of the AGA-7 is the most important part of the assembly. It is formed from a number of layers consisting of either tin oxide (SnO2) or silver oxide (AgO). This layer is designed to monitor the current passing through the fuse and activate the self-protection mechanism when the current reaches a threshold level.The insulation layer of the AGA-7 acts as a barrier to stop any energy from passing through the fuse. This layer is designed to prevent accidental damage to the internal components of the fuse, as well as providing additional protection to the device itself.In conclusion, the AGA-7 is a high-performance fuse with an impressive performance record. Its working principle is effective and efficient, with its component architecture designed in such a way as to provide maximum protection for circuits and devices from all types of overload conditions.
