Surge Protective Devices are designed to protect against transient surge conditions. Large single surge events, such as lightning, can reach hundreds of thousands of volts and can cause immediate or intermittent equipment failure.
A surge protection device (SPD) is connected in parallel with the load. The input supply is given to the load through the circuit breaker, and it is also given to the SPD in parallel. The main part that stands out is the ground or earth connection.
Surge Protective Devices (SPD) are used to protect the electrical installation, which consists of the consumer unit, wiring and accessories, from electrical power surges known as transient overvoltages.
A surge protector limits the voltage supplied to the electrical devices to a certain threshold, by short-circuiting current to ground or absorbing the spike when a transient occurs, thus avoiding damage to the devices connected to it.
Surge Protection Devices (SPDs) protect sensitive electronics like computers, TVs, and tablets from unwanted power surges or “spikes." As utility grids become more unstable due to increased demand and decaying infrastructure, surges are becoming more frequent.
All types of surge protectors guard against power surges and spikes, but there are differences. Find out which is the best one for your needs with this guide.
Powerful and dependable, ABB’s OVR Data Line Surge Protective Devices help protect critical loads from damaging electrical surges and high-energy disturbances.
Whether your need is for residential, commercial or industrial, our complete portfolio of surge devices offers a range of protection from 36kA to 1000kA and guarantees the highest form of electrical system safety with a unique cascading option during the installation process.
A surge protective device (SPD) is designed to protect electrical systems and equipment from surge events by limiting transient voltages and diverting surge currents. Surges can originate externally, most intensely by lightning, or internally by the switching of electrical loads.
Surge protective devices (SPDs) are items of equipment whose key components can be varistors, suppressor diodes, gas discharge tubes (GDTs), or spark gaps. Surge protective devices are used to protect other electrical equipment and electrical systems against impermissibly high transient overvoltages and transient currents.
