Fuses

Within electrical electronics, a fuse is a device intended to disrupt the flow of electricity of a short circuit or overload condition in an electric circuit. The 0662.050ZRLL is an example of a fuse used for industrial applications, and has a maximum voltage of 400 V and a nominal current of 50 A. This fuse is a Ferrule type, meaning it is made up of a thin copper wire ferrule that is surrounded by a void space full of filler material and a ceramic body for insulation. This type of fuse was chosen to be used in higher current applications due to their resistance to inductive heating and more effective use of material.

Application Field

The 0662.050ZRLL is an industrial-grade fuse and is typically used in factory automation, railways, motor systems, oil & gas, automation, energy generation and distribution, motion control, and instrumentation and control systems. Due to its current capability and its relatively small size, the 0662.050ZRLL is often used in applications with relatively high current, such as motor starters, relays or other equipment draw large currents. It is also compatible with voltage transients due to the Ferrule design.

Working Principle

The 0662.050ZRLL is a low voltage, high current fuse that its purpose is to protect circuits and associated components from excessive current. Fuses work by using the property of heat and its associated properties to answer to an increase of current over time. After the fuse is inserted into the circuit, the wire will heat up because of its resistance of the flow of electric current; for an overcurrent situation, the wire experiences a sudden increase in temperature that raises faster than its insulation material or its housing can withstand and then melts, breaking the circuit protection.

The 0662.050ZRLL is equipped with a Built-In Meter, usually connected in series with the protected components. This Built-In Meter measures the current flowing through the fuse and if it exceeds the configured threshold or it\'s nominal rated current, this will trigger connection and power disruption. The fuse is designed to fail once the current reaches the specified current set point, interrupting the flow of electricity and preventing further damage.

Additional Characteristics

The 0662.050ZRLL has some additional characteristics that make it an advantageous choice for industrial applications. It has a broad temperature range of -40C to +125C meaning that it can be used in a variety of different conditions. It also has a high Voltage Transient Protection, meaning that it is well equipped to answer to sudden changes in voltage levels in the circuit. Moreover, the fuse has high Short-circuit protection with a minimum breaking capacity of 10000A (at 50V) and a nominal duration of 0.67s, making it an ideal option for safety applications.

Conclusion

The 0662.050ZRLL is a Ferrule type of fuse with a maximum voltage of 400 V and a nominal current of 50 A. It is usually used in factory automation, railways, motor systems, oil & gas, automation, energy generation and distribution, motion control, and instrumentation and control systems. It works by using the heat and its associated properties to answer to an increase of current over time, melting when the current reaches the specified current set point and preventing further damage. The 0662.050ZRLL has a broad temperature range, and a high Voltage Transient Protection and Short-circuit protection, making it an advantageous choice for industrial applications.
