Introduction

The FRS-R-3/10 is an electrical specialty fuse designed to protect wires and electrical components from overheating due to current overloads or short circuits. It is a resettable fuse which combines the performance of a fuse with the convenience of a circuit breaker. The FRS-R-3/10 offers an efficient, convenient, and affordable way to safeguard electrical circuits.

Application Field

The FRS-R-3/10 can be used in a wide range of applications, including consumer electronics, vehicles, aircraft, communication systems, defense systems, household appliances, medical equipment, and industrial equipment. It can also be used in sensitive electronic applications with precision circuitry and microprocessors.

Design and Construction

The FRS-R-3/10 is a resettable fuse with a glass fusible link inside a plastic case. It is a compact, one-time-only fuse that does not require replacement after it trips. The fuse has a high current rating and is suitable for installations up to 250 V AC or 30 V DC. It is UL Recognized and RoHS Compliant and can be used in many environments, including humid or wet conditions.

Working Principle

The FRS-R-3/10 operates on the same principle as a normal fuse, with one key difference: instead of melting and needing replacement, it resets itself after an overload. When the current through the fuse exceeds its rating, a fusible link inside the fuse will melt, opening the circuit. This activates a resetable thermal switch that stops the current and disconnects the circuit until the switch is reset.To reset the switch, the fuse must be disconnected and then reconnected. The switch is designed to allow only a single reset operation, after which the fuse will need to be replaced. The fuse also includes an indicator light that will tell you if the fuse has been tripped.

Conclusion

The FRS-R-3/10 is an electrical specialty fuse designed to protect wires and components from overheating due to current overloads or short circuits. It combines the performance of a fuse with the convenience of a circuit breaker to offer an efficient, convenient, and affordable way to safeguard electrical circuits. It can be used in a wide range of applications and has a high current rating. The fuse is also easy to reset and includes an indicator light.
