Circuit protection is a prerequisite in designs that must be efficient due to the greater unpredictability of today's technologies. There are many different potential sources of damage, but how can we protect our circuits from such damage?
Many circuit protection techniques are often concerned with outside effects, but sometimes circuits need to be protected from themselves. Protection techniques of circuits include the devices such as Zener diodes, choke, decoupling capacitors, and protection diodes. One classic example of self-protection is short circuit protection by using a fuse.
Circuit Protection using a Fuse:
Though not all circuits suffer from this problem, some designs may incorporate circuitry that has the potential to draw overcurrent during fault conditions.
A push-pull amplifier, for example, may be able to connect to external devices, but it may also be reliant on those devices having a low impedance. The push-pull is at risk of getting short in this case. While the amplifier may be capable of handling the current, other circuit components may not. In this scenario, a fuse can be used in series with power supply, inputs, and outputs to guarantee that the circuit does not draw harmful current quantities.
Enrgtech offers a range of high-quality circuit protection kits from leading brands with different features and excellent designs. These designed kits have built-in adjustments of various protection tools for easy storage and transport. The kit also includes other essential parts and professional tools needed to carry out your job.
Features of Circuit Protection Kit (CPK):
These kits provide engineers with several overcurrent safety solutions in a range of rated currents and voltages for quick prototype testing. The kits include a variety of automotive-grade, high-current, high-voltage, and IEC-certified types in various footprints and current ranges.
Other fuses in the kit provide dependable overcurrent protection in three different surface-mountable footprints. Single-use thin film SMD fuses, for example, are explicitly intended for applications that require one-time acting fuses, which allow for a physical break in the circuit if a short circuit occurs, obviating the need for a circuit reset.
Another example of CPK from RS PRO Automotive is Surge Protection Fuse Kit.
This automotive fuse kit from RS PRO comprises 16 different fuses and two fuse holders. With a portable fuse tester, these are perfect for on-site and on-road testing. In addition, the boxed design keeps all automotive fuses neatly organized. The fuse kit complies with British and international requirements for electrostatic discharge prevention (ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007).
Applications and Benefits:
- Circuit protection kits are an indispensable part of home and office electrical systems.
- They can prevent electrical fires and shocks and damage to electronic components.
