Surge protection devices with different voltage rating, current rating, configuration, etc. offering high level of protection to the whole house electrical grid to effectively stop the damaging surges in their tracks. Hook on to these units to secure your electric and electronic devices as surges can be detected only by precise surge suppressors that will block and discharge any voltage exceeding the threshold level to the ground.

The choice of SPD or surge protection devices should be in accordance as per relevant standard as well as the field of application otherwise these protection units itself blows off which is because of non-complying with relevant standards or can be due to not being an appropriate fix for the application. It works with components such as metal oxide varistors, Spark gaps or Gas discharge tubes of proper ratings which are used for manufacturing of these protection units. For defending the vulnerable devices against power surges of any magnitude, you need to choose SPD application specific SPD according to the current and the voltage rating and plug in these defending installation to the power outlets.
