What is a control circuit fuse?
What is a control circuit fuse?
Control circuit fuses have many different voltage ratings, ranging from 32Vac to 600Vac, and interrupting ratings up to 100kA. Adverse consequences typically result when a system fault occurs and an improperly sized fuse attempts to interrupt an overcurrent event.
Can fuses be connected in series?
Fuses are always connected in series with the component(s) to be protected from overcurrent, so that when the fuse blows (opens) it will open the entire circuit and stop current through the component(s).
Is a fuse a control device in a circuit?
Fuses, fuse elements, fusible links, and circuit breakers are used as circuit protection devices. Circuit protection devices are available in a variety of types, shapes, and specific current ratings. A fuse is the most common type of overcurrent protection device.
Where is fuse connected?
live wire
The fuse wire is always connected in the live wire of the electric circuit because if the fuse is somehow put in the neutral wire in the circuit, then due to excessive flow of electric current when the fuse burns, current will stop flowing in the circuit, but the appliance will still remain connected to the high …
What’s the voltage of a control circuit fuse?
Control circuit fuses have a variety of different voltage ratings, ranging from 32 V to 600 V, and interrupting ratings up to 100 kA. As the physical size of these fuses does not vary with voltage or interrupting rating, the most common cause of misapplication is due to improper voltage or interrupting rating selection.

How is the current rating of a fuse established?
The necessary voltage rating of a fuse link is established by its required operating voltage (taking into consideration the voltage drop of the fuse link). The current rating of a fuse link (I N Fuse) is established by the max.
How to choose a fuse for an overcurrent protective device?
Select the fuse type. Select from time-delay fuses for inductive loads or fast-acting fuses for resistive loads. Select the voltage rating required. The voltage rating must be equal to or greater than the circuit voltage for the proper application of an overcurrent protective device.

What is the function of a fuse in a circuit?
The fuses to be considered are current sensitive devices designed to serve as the intentional weak link in the electrical circuit. Their function is to provide protection of discrete components, or of complete circuits, by reliably melting under current overload conditions.
What do you need to know about fuses?
About this guide Fuses are current-sensitive devices that provide reliable protection for discrete components or circuits by melting under current overload conditions. Choosing the right fuse for your application can be an overwhelming, time-consuming process, even for a seasoned electronics design engineer.
What kind of fuses do power control transformers use?
POWR-PRO time-delay fuses such as the FLSR_ID, LLSRK_ ID, IDSR, or JTD_ID series have sufficient time-delay to permit transformers to perform when the fuses are properly selected in accordance with the NEC®. Fusing Control Transformers With one exception, control transformers are protected the same as regular transformers as discussed below.
