Introduction

Fuses are energy-sensing devices used in power management systems, to ensure safety by providing a circuit breaking function. One such type of fuse is the 5ET 3.15-R, which is designed to protect low-voltage DC circuits against overloads, short circuits and fault current inclusions. The following will discuss the application field and working principle of the 5ET 3.15-R fuse.

Application Field

The 5ET 3.15-R is manufactured by Schurter, a Swiss electronics company, and is a low voltage, Class R fuse, compliant to IEC standards. It has a low breaking capacity, making it suitable for a variety of applications, particularly where safety is a priority. It is compatible with all standard PCBs, allowing it to be easily integrated into existing systems and is commonly used in consumer electronics, health-care equipment, instrumentation, LED driver circuits, power supplies and telecommunications.

Design and Working Principle

The 5ET 3.15-R incorporates a physical design that protects against temperature and shock. It is housed in a polyamide casing, which provides a robust and reliable seal, which in turn helps protect against corrosion and dust ingress. The fuse is constructed from a glass tube, with two electrodes connected to a metal spring, which act like a switch, connecting and disconnecting the circuit depending on the current flowing in the circuit.The 5ET 3.15-R has a dual-action working principle which, when triggered, will both open the circuit and trip the circuit breaker. This protects the system from any future damage; isolating the current and resetting once the fault has been rectified. This dual-action design is what makes the 5ET 3.15-R safe and reliable.

Specifications

The 5ET 3.15-R has a rated current of 0.1-3.15A and a breaking capacity of 3A. It is also rated for a maximum operating voltage of 32V DC. The resistance is also very low, which means it can be used in applications which require a low impedance circuit. It also has an operating temperature range of -55°C to 85°C and a mechanical life of over 10,000 cycles. All of these features make the 5ET 3.15-R an extremely versatile and reliable fuse, suitable for a variety of applications.

Conclusion

In conclusion, the 5ET 3.15-R fuse is a versatile, reliable, low voltage DC fuse, compliant to IEC standards, suitable for a variety of applications. It has a dual-action working principle, which makes it safe and reliable, and a robust design that ensures a long mechanical life. It is also rated for a maximum operating voltage of 32V DC and a maximum current of 3.15A. These features make the 5ET 3.15-R a great choice for any power management system.
