Are you worried about your electronic devices getting fried due to voltage spikes? Well, worry no more! We have the answer for you – the surge protective device.
A surge protective device, or SPD, is a device that is designed to protect electrical equipment from voltage spikes or surges. These spikes can be caused by lightning strikes, power outages, or even just switching on or off high-powered equipment.
SPDs work by diverting excess voltage away from the equipment and towards ground. They do this by using metal oxide varistors, or MOVs, which are highly conductive materials that can absorb excess voltage and divert it away from the equipment. It means that your equipment is protected from potential damage, and you won’t have to worry about costly repairs or replacements.
So, if you want to protect your valuable electronics, invest in a surge protective device. They’re affordable, easy to install, and could save you a lot of money in the long run. Don’t let voltage spikes ruin your day – get an SPD today!
Maximum discharge current Imax The maximum discharge current Imax is defined according to the estimated exposure level relative to the building’s location. The value of the maximum discharge current (Imax) is determined by a risk analysis (see table in Figure 1). Fig. 1 – Recommended maximum discharge current Imax according to the exposure level Exposure […]
Surge Protection Devices (SPD) are used for electric power supply networks, telephone networks, and communication and automatic control buses. The Surge Protection Device (SPD) is a component of the electrical installation protection system. This device is connected in parallel on the power supply circuit of the loads that it has to protect (see Fig.1). It […]
Calculating the appropriate fuse or breaker size for a branch circuit is straightforward. For most applications, an overcurrent device should be sized about 125% of the load’s rated amperage. This way, your load will be protected from electrical short-circuit.
